I have been talking to Chris about changing my sub from an A5-350 to an A7S-450 with the 1,300 watt amp. Has anybody hear listened to the A7S-450 and compared it to the A5-350? I would like to hear what your thoughts are on this sub and how the two compare. Thanks.

Is it available yet?

Unfortunately outside of the company, no one has heard one. :)

Wait, I take that back, we had an open house in June of this year, and we had some customers listen to it.

The product isnt even listed on the website as an item yet. While its online, its not listed on the frontpage yet, and doesnt have a product picture.

I do have one in my living room. ;)

Just thought ide throw that in.

I'll put it this way.
It'll be better than the A5-350.
While the 350 isn't bad, there is no replacement for displacement. :)
If you can afford it, get the A7.

The A7S-450 is a sealed unit.

While there is no replacement for displacement, they are both different beasts. :)

Since both of these are ED products, I should get an unbiased opinion from you. How do the two compare music wise and HT wise?

ok, so do you not plan on answering the questions of the op?

I talked at length with Alex just last week concerning the two and when I asked what he would place in his home for the best combo of HT and music, he didn't hesitate to recommend the A7-450. The 1300 watt amp will give you a better low end and only sacrifice 1 or 2 db overall. Definitely said you can feel it in his livingroom.

Should be a great HT sub for the money. We spoke specifically about how Master and Commander sounded. In a word, awesome he said. This is the sub that has me geeked about ED. I had almost made up my mind to get an Epik Caliber or Castle until my conversation with Alex.

Thank you tvckmiller. Due to some space constraints, I am looking at a modified A7S-450. My wife will be happier if I place the new sub in the built-in (where old sub is currently) rather than out in the room. This will place my front speakers, tv and sub all in the same plane.

Changed order to A7S-450 with 1,300 amp. Looking forward to my new sub. WAF should be higher on this sub (compared to A5-350) since it will be hidden behind French doors when not in use. Looking forward to hearing this sub. If anyone gets this sub before mine comes in please post your thoughts.

Just when all the talk about it gets started, it's not on the website. Is the hype hurting A5-350 sales? The sealed 18 sounds like the better choice to me due to the size vs. performance factor alone. By the way Alex, if I jumped out there with a quote from you too soon, then I apologize! It's just easy to get pumped about a sub like this when the market is begining to really take off in the < $1000 sub range.

Up until recently, a 12" driver and 350 watts was all you could expect from that price range. The new ED and Epik subs have got some serious market consideration lately which makes me wonder when and if we might see a 15" HSU model soon. Simply put, I have had my fill of the smaller drivers and am really interested in 15 and 18" displacement now.

I hope you guys make this sub or at least high power single 15 or 18 sealed. Again, if it's not too expensive, I bet most people on this thread would prefer the smaller footprint and bigger displacement for WAF if nothing else.

Interested to her about this.

what are the dimesions/weight of this unit?

It was on their site, but it is gone now. You used to be able to find it when you selected "Show All" under powered subwoofers.

what are the dimesions/weight of this unit?

Front firing 18" speaker (190v.2) in a sealed cabinet 22.25" x 22.25" x 22.25" not including spiked feet. I can't remember the exact weight, but some where around 130 pounds.

When it's right they'll repost it.

If it weighs more that is a plus to me.:)

The sealed 18 sounds like the better choice to me due to the size vs. performance factor alone.


the sealed version is going to be less efficient. using the thiele-small parameters for the 15" and optimizing enclosure for sealed (qtc=.7) as well as for ported, the sealed enclosure is 3.4 ft^3 and the ported is 5.4 ft^3. the sealed gives up 6dB from 20-30Hz. so it would take 4X the amp to bring the sealed SPL up to ported SPL across this key frequency region.

if the max SPL of the ported version for sale is driver limited, then even with 4X the amp, the theoretical sealed version won't match it. it will have other advantages, but not in SPL performance.

Anyone figure out why it's not on the website any longer?

I am guessing it is not ready for sale and they don't want to take a million questions on something that has incomplete information.

I know of one that is currently in the woodshop. :)

Anyone figure out why it's not on the website any longer?

We want to get the one sitting in the corner to get finished so we can have real pictures online before we start selling them.

The product was added to the site and I forgot to set it up to not appear when I was entering things.

Even the small pictures for product features were wrong, they were from the A5-350.

Does the A7S-450 use an off the shelf 190v.2 or a variant of the 190 platform?

That is a good question. I asumed that the A7-900 used the 190v.2 and the driver used in the A7-450 and A7S-450 would be the same, but I notice that the A7-900 states built on Ov.2 platform not 190v.2. Is there a difference?

wow, so much cool stuff coming out

where were all these awesome subwoofers back in 95 :(

:)

I am currently completing the build-out of a basement HT/audio room 26ft.x22ftx8ft = 4,576 ft3 with an open stairwell at one end. I have 7.0 surround at this time and a 7x200wpc amp, 70” rptv.

As of last week, I was planning on going with 2 x eD A7S-450’s. I am new to subwoofage, and would appreciate your opinions on what the following combinations of eD subwoofers would provide (pros and cons of each setup). My preference is toward musical accuracy, but would like low-end "ooph" during HT. I have plenty of room for any of the combinations and the HT/audio room has also been deemed “the mancave”, so WAF is not a factor. Best guess is 70% music and 30%HT usage.

a) 2 x A7S-450’s
b) 2 x A7-450’s (ported)
c) 1 x A7-900

Thanks,
Steve

I think all three of those are good choices and I do not think you could go wrong with any of them, but with your 70% music I would go with the sealed sub.

Duals should gain you a more even frequency response with proper placement and probably treatments, but even a single sealed or ported sub will probably be enough (certainly the ported). The A7-900 or either combination of duals will pressurize your room with ease. For musical SQ questions, I'd ask Alex. He's got the only sealed proto out there currently.

Steve you almost sound like me. Musical accuracy is my primary requirement. However, my room is much smaller than yours (~2000 ft.^3) and I do watch a lot of movies. Punchiness, tightness, well-defined, bass line with vast distintness between notes is what I am after. Further, my sub needs to be accurate and handle transients superbly. I really dont need a sub that plays all the way down to 20 Hz and beyond. Like you I do not have to deal w/a WAF at all. Just have to please the most important person in my life-which, of course, is me...:p:p.

Hello Ron may I ask who is Alex? I would like to ask him some questions as well regarding the A7-900. I prefer the sealed version of the 450 myself.

Alex lincoln @ ED..I'm sure he has posted in this discussion.

Did I miss an e-mail from you?

If ya could, could you go ahead and send me a prototype of anything, im not picky. :P haha jk.

Does the A7S-450 use an off the shelf 190v.2 or a variant of the 190 platform?

It uses the 190v.2 driver. The same driver that is in the A7-900 that Craig has as the number one sub for music or HT. I confirmed this with Elemental Designs. If the A7-900 is a good musical sub then the A7S-450 should be also.

Sealed enclosures typically use less airspace than a properly designed low tuned enclosure.

I do like the unit a lot. Its just that I PERSONALLY prefer the vented cabinets. I come from a car audio background. :)

I will do neither of those. The A7S-450 is actually Casey, the warehouse managers', He is living with my wife and I. I have an A7-600 at the house, waiting to get an amp and subs.

No eQ.2 is being used right now, and I am more than happy with it.

I dont have an LMS at home to get measurements, and dont have a hand held mic at this time to take measurements.

I would add another A5-350, still a lot of output for $600 and adding another will help with your output and even out room nodes a little.


so then the ported sounds better than the sealed

Not better, but different. As ive said before, its personal preference.

I typically watch tv or movies with a subwoofer, so the vented units work great and sound plenty good for my music listening, as Chris mentioned once, with the crazy stuff he listens to, any of our vented units can hold their own. :)

Alex, My A7S-450 went in the paint room Monday. Does that mean it will be shipped out this week?

Excuse me Danke. I did not mean to offend you. Was actually kinda joking but I see you took me wrong. To answer your question regarding eD I will say no I don't. But, am seriously considering it. Do plan on getting the eQ.2 once it is available. Why do you ask?

The eQ.2 is already available for sale on ED's site. It is listed under eD processors on their main page.

Where did you find that picture? It looks like that is a picture of my sub. I had the height cut down so that it would fit in my cabinet. The width and depth were increased to make up for the loss in height. I found the picture on ICIX, Ben Milne, 10-30-07 pic # 5253. Thanks Ribbit.

Would it make any sense to get one A7S-450 and one A7-450 to get the best of both worlds? Or would they not play well together? My setup will do about 70/30 HT/Music if that helps any.

I'd love to just go with an A7-900 and call it a day but I already have a coffee table... :p

If you combine an A7S-450 with an A7-450 you are talking about the same external size box as an A7-900.

True, but at least I would have a little more flexibility when it comes to placement. I'm not as concerned with size, (No WAF here yet :cool:) but it is a factor. I am more concerend with SQ and output.

You would be better off with two A7-450's. Sealed subs do not sound any better than ported subs.

2 subs is already not the easiest thing in the world to pull off well.

2 subs that have a completely different frequency response would be a nightmare.

Hey Chris I have replied back to you several times. Did you NOT get it? Or, just have you been too busy to get back to me? I am sure you have been very busy. Let me know if you did not get my reply. Take care.

It looks like a world beater for the money. I can't wait till they get numbers posted and someone does a listening test.

How do you post a picture if you have your picture stored only on your computer (iphoto)?

I like the sub. After I slid it into my built-in it did not look like a huge sub. Sub sounds very clean. Bass is very distinct (not muddy) even at low volume it has very good punch. I have a large room (a little over 11,000 CF) and you can feel this sub pressurizing the room. With this sub you are drawn into the movie a whole lot more. It is what my system was missing with my other smaller sub. I have not had a chance to try any music with it yet. Music will have to wait until Saturday. Very happy with the first A7S-450.

I still need to work on calibration, but my SPL meter got left at the office. I just did a quick set up using audessey.

Very nice mjg!!!!!!!!!!!!!! Looks like it was meant to be there. Congrats my friend. Be sure to let us know how it does with music. Have a great day.

Nice setup mjg... I have been deliberating between this and the A5-350. Would you know the dimensions on the A7S-450? Since the unit is not on the website, I am unable to determine size.

that's because MJG's A7S-450 is custom sized :)

Front firing 18" speaker (190v.2) in a sealed cabinet 22.25" x 22.25" x 22.25" not including spiked feet. The grille will add one inch to the depth also. Choice of 550 watt or 1300 watt amp.

I started to go with an A5-350 and then I saw the A7S-450. I knew that my wife would be happier with it built in. She has only seen it in place and it does not look that big when you can only see the front of it. If I pulled it out I think she would be shocked. For HT this sub is a huge (10x) improvement over the 10" ported NHT sub that I was using. Now you feel like you are involved with the action.

I calibrated the sub and it does a good job with music as well as HT. Blends well with my RBH signature speakers. Nice tight clean distinct bass. This sub is a good choice for music and the 18" driver even in a sealed cabinet moves a lot of air giving it a lot of punch for HT. I feel like my money was well spent. I will be interested in what other have to say about this sub.

I put in Independence Day and turned the sub up a little bit. I let my little boy watch some of it and he said that the sound from the sub scared him. I asked him if he wanted me to turn the sub down and he kept saying no.:)

haha, that reminds me of my son today. I played the pods emerging scene for him and although he was a bit scared, he wanted to watch the rest of the movie (he thought it was just too cool).. He's only 4 though so i told him he could watch the incredibles instead (hey there is plenty of bass there also).

Awesome sub though. Definitely a good bang for the buck sub.

This is why I believe an 18" sub w/1300 watts rms of power would have the police out here constantly knocking on my door. :eek::eek: No pun intended. Truthfully, I would love a sub with that kind of capability but cant afford to get evicted either. You know I thought I may have heard your sub up here in Henderson County yesterday.........LOL!!!! :p:p

I only have one house beside me and it is a second home (vacation home). The people that own it are only down three or four times a year. Also the walls of my family room are very thick 1/2" drywall, 2x6 studs, 1/2" OSB, 1" insulation board, 1" air space and 5" of stone for a total thickness of 13-1/2". I have turned my system up to 110 db and gone outside to see how loud it is. I discovered that you can hardly hear it outside. The wall between the family room and the rest of the house is 10” thick. I like to play my movies loud. :)

You truly are one lucky guy. I think you have made the right choice. So, was it your sub I heard up here yesterday........LOL!!!!! :p:p

Mike,

That looks awesome.

I'll have to get on JJ about getting your grill finished so you don't have to see the giant silver disc below the TV :)

Also, you somehow made an 18" driver look tiny, congrats.

That looks great Mike.

:)

As for the sub being too loud outside. Having an A7S-450 at my place, and putting it through its paces, I can go outside, and be 10-15ft out the door and it becomes none existent, in an 80+ year old home. Unless you live in a cardboard box, the insulation, and walls should do a decent job to keep the bass in.

I've neighbors within 20' on each side of me (dang tract housing) despite being on a 1/3 acre lot.

Having placed an order for an A7S-450 this morning (LT1300 upgrade as well) I'll have the opportunity to test this also. Of course, having such an incredible sub may limit my listening times to before the kids go to bed, but this sub will offer real bass extension at lower volumes than the sub I'm replacing.

And for the price point that this unit is selling at.... unbelievable. Not to mention free shipping!!! How much did the unit weigh in at mjg100?

The drive and amp alone would have cost me as much as the whole unit if I were to have purchased elsewhere. How these internet direct dealers accomplish this pricing is unbelievable.

MJG100,
Are you using anything to equalize your sub to the room? I have ordered my two AEP25S-900 (dual sealed 18"s with a EP2500 amp). I am looking forward to see how they perform without any tuning in the beginning. Any regrets going with the sealed sub vs ported? I am looking to really pressurize the room with lots of bass that you can feel in your chest.

I am looking to really pressurize the room with lots of bass that you can feel in your chest.

From looking at the pictures above you can see one of the reasons that I went with a sealed sub. A big ported sub would not fit. This sub keeps the wife happy and it is powerful enough to make me happy as well as clean output distinct. I have a huge room (11,000 + CF) and you can feel it pressurize the room. As I said above my 7 year old said that it scared him and he is used to listening to movies loud with my old sub. I think if you are going to get a sealed sub you should get one with a large driver with lots of watts so that it can move some air. I would definitely recommend this sub if you are in the market for a sealed unit.

Right now I am trying the sub using Audessy on my Onkyo 805 and it sounds good. I may add parametric equalizing later using the DSP1124 or EQv.2 by ED.

I ordered an eq2 when I placed my order mjg as I am nearly certain I'll have placement / room issues to contend with. WAF requires a very specific location for an all black sub and therefore, I suspect I'll be contending with some hard peaks.

They aren't in production yet though so it'll be 2 months before that arrives, so I should have 4-6 weeks to enjoy the a7s first.

looking forward to having a sealed sub once more. I've never experienced a single ported sub that performs with the same musical ability as a sealed. Granted it takes more guts to perform to similar spl's, but if 1300 won't do it in my room... well, I guess I'm deaf :p

Cheers,

michael

I hope others that get the A7S-450 come back and post in this thread. I would like to hear what they have to say. I also hope Craig tests one. If others post about their A7S-450's We canl change the thread title to the Official A7S-450. :)

I suppose I will be alright then :) I will pick up the eq2 when they are ready to ship. I have ordered basically the same sub as you, except there are 4 of their 18 inch drivers, with two of the Behringer EP2500 amps. eD has been great to deal with, I am looking forward to getting my subs.

Are you getting four A7S-450 subs or two subs that have two 18" drivers in each box? An A7-900 but with more power. What size is the room you are going to be using them in?

mjg100,
Basically they are two of the A7-900's but sealed with more power :). The room is roughly 4500 cubic feet, open to the rest of the house. I am going to put french doors in at some point to close it off to the rest of the house.

With a little room gain and a little eq, you should be flat to <10hz. ;)

Waiting for woodshop with my A7S-450(1300) as of this afternoon.

From what I recall, from here it'll be 2-2.5weeks to receipt based on a conversation last week with the sales guys.

Depending on how it sounds, if I decide I need more bass later it'll be a second 7S-450. Although I may order it custom without any finish and add some veneer to it for more placement options (given that this one has to be essentially hidden). Perhaps some walnut burl or some wenge veneer. hrm... We'll see once I run some room tests after receiving the eq2 and playing with it a bit.

You will be able to blow the roof off of that room. If you place one near field it will vibrate you out of your seat.:)

I'll bet he breaks glass within a week. :)

Yeah, Whats up with the "giant shiny silver discs"? Why can't we have them with black cones? We finally got TC Sounds turned around with black cones and then they up and close shop!

Seriously, I bet more people would be attracted to them if you had a black cone option. I know the grill covers them up, but some of us like to let it all hang out. :D

Dr V

I just finished the new drywall, I have the floor to do and the trim work. The french doors are actually an exterior french door that has one side fixed. I am going to convert that to dual inward swinging interior doors to help with sound isolation. The room has 8 36"x54" windows plus the two french doors, so there is a ton of glass that has to be covered up with heavy curtains.

I should probably get the grill covers with the sub, uncovered it could be a bit distracting during a movie :)

I am hoping that I will be able to scare some friends with some heavy bass on movies :)

Scaring friends?? I think its more like you will be scaring your neighbors with movie bass....

where did you guys get online info from eD about sealed subs???? I don't see any info on their website about sealed subs.

Chrislee,
Just shoot them an email or give them a call, eD would be able to help you out about their sealed subs. They are not on their website yet.

Ben @ eD posted on the icix forum this morning that orders not received by end of business today will not be delivered by X-Mas. Sounds like these guys have their work cut out for em for the next few weeks. I like to worry with the best of them, so even though my order was placed last week, I needed a little reassurance that it would still get to me by Christmas (confirmed by eD this afternoon that wont be a problem :)

My room has the following windows and doors:
One 7' x 16' french gliding door
Two 6' x 12'-6" windows
Two 2' x 6' windows
Four 3'-6" x 3'-6" windows
One 5'-4" x 8'-6" French door

I turned my sub up some and I really did get worried that I might break a window.

mjg100,

Is it possible to break a window with bass? I could see them rattling, but enough bass to actually break them?

How are you enjoying your sub so far?

As far as breaking windows. I do not know if my sub could do that, but as big as my windows are I do not want to find out.

http://i243.photobucket.com/albums/ff112/mjg100photo/P1000506.jpg

It would take an astronomical amount of bass to break the windows, and when I say that, I mean either the seals holding the window in place or framing work around it, and when i say break, i mean crack. ;)

You have vehicles producing bass in the 150+ db range not breaking glass.

I've broken a window before w/ my sub...

of course, it wasn't installed and was leaning somewhere it shouldn't have :) Just fell and smashed...

However, "window rattle" can certainly affect your sound quality and over all enjoyability of the room and movie :)

Uhm......not quite my friend.

you don't need pressurization at 30-50hz to break or crack windows.....if your sub is capable of producing enough output at 15-20hz (120dB in room, etc), you can easily crack some windows.....Believe me, I speak from experience!! ;)

try 16hz tones at reference mode with a pair of low tuned large EBS subs, and you WILL be taking trips to home depot to replace the windows before the wife gets home!!!

I've done 141.2 at 17Hz in a hatchback..air will begin chuffing out the defrost vents before anything else. Even when I sealed those, air would still find ways out of my car, like through the door handles.

Granted, home glass is different, and covers much larger spans so I could see it cracking from flexing too far, but at only 120dB? How big was the window?

I do not know what my subs are going to test out SPL wise, but its nice to know that the windows I spent my summer putting in have a lifetime warranty on glass breakage (just in case :) )

apples and oranges there Chris....I've had 4 JL w7's pumping with 4000W, doing easily close to 145dB @ 18hz in an e46 330ci, and as you said, it didn't even flinch.

different scenario here

Granted, home glass is different, and covers much larger spans so I could see it cracking from flexing too far, but at only 120dB? How big was the window?
window on the far right there:

and these two puppies pumped the wavelengths:
http://i44.photobucket.com/albums/f38/ssabripo/DIY%20Ava18%20subs/ava18subs001.jpg

My windows are 6' wide and my sub faces the window shown. I have a second window just like the one shown above on the side wall. When the sub put out a strong low burst the glass in the windows would flex.

Ahhh...with the distances involved there I could see it.

Did you get a chance to see how far you got your window flexing before cracks?

Maybe you should install tempered glass windows :)

Oh it flexed alright! ;) I didn't actually go and measure the flexing, as I wasn't expecting the darn thing to crack, but it wobbled like Jermaine Taylor being hit by Kelly Pavlik! :D

Tempered glass was indeed the option I went with.....you think wisely Chris!

woot, my A7S-450 is in final assembly... won't be long now :)

michael

How do you check the stage it's in?
I just ordered one over the phone,yoohoo!

Orders placed on the web require an account and once placed, are trackable. I'm not sure if that is the same for phone numbers unless you had an account created online before purchase?

You'll have to check w/ the online sales team and they can hook you up. Chris and the team are excellent.

See, I told you they were on top of their game ;)

Any word on tighter estimates for the eq/2 yet Chris?

michael

ordered a pair of A7s-450's. I specifically requested black subs :) Thanks Chris for answering all my newbish questions. Of course, I just ordered and so am still in the "awaiting woodshop" phase.

question: I have an brand new Onix RDES for bass eq. Should I use that or perhaps get the Eq/2?

I am anxious to hear what other A7S-450 owners have to say about their sub. I am very happy with mine.

mjg how big is your tv in the picture?

My tv is a 50" and I have a 106" screen that drops down in front of the tv when using my projector.

Great idea. I was dual for a while, but couldn't figure out how to permanently install the screen without making it look pretty rough.

MJG100, did you place rubber feet under your sub? I was chatting w/ Chris today about my sub (just getting the grill painted now, but it's ready to rock otherwise :)) and he mentioned that your original design called for shock absorbing feet underneath due to the ultra low clearances?

The reason I ask is that yours was a bit unique in that it has no feet where they normally are and as a result you had a custom grill and a few other unique properties :) So, the unit I'm receiving is just a <lil'bit> different from yours. Mine got stuck in a couple spots due to it being the first production run (no custom parts) A7S-450 out of the factory... I must say I'm looking forward to receiving this and putting it through its paces. I'll take a host of pics when I receive mine, although I think that eD may do that for me as the poster child for the website.

Man, this bass-less movie experience has sucked the last few weeks. I'm SO looking forward to having a good sub once more (and a significantly upgraded one at that.)

michael

I'm looking forward to mine even though it wont be here at least for a month..

Mine is isolated from the floor with 1/8" thick felt.

Ah, is the isolation sufficient for your room? That is reassuring if so as the bracing and rigidity of the box must be impressive.

Also, for anyone else, the 2 A7's are now officially on the website for real now.... really :)

michael

No pictures though..

Mine is the first official production unit and I think that the grill paint is drying, lol.

I don't know if they'll take pics of mine before shipping or not though. Apparently the CNC programming and such for the Grills (yours too MJG) is done and was run through it's paces earlier and has gone through paint now. If they don't post pics, I'll take a few extra (that I wouldn't normally) for the forum.

michael

Oh, we'll get pics before it leaves.

Yes..we will.

There we have it :)

No. I am still waiting. So far my kids have not bothered it. When I get it I will take a few pics with tv and some with projector screen.

MichaelTS, did u get your sub. Any thoughts so far?

When I saw this thread revived I thought that another A7S-450 had been received. I have been waiting to hear what other owners think of this sub. I really like mine but I am still waiting for my grill to be delivered. Grill did not come with the sub. I was told that it would be shipped separately. I placed my sub order on 10-13-07. I received my sub, less grill a month and a half ago. Three months have almost gone by and I am still waiting for my grill.

I did not get my sub due to a loss at Fedex (how you lose a 140lb box that is 3'x3'x3' is beyond me though). eD did do a rush replacement build on it though and it's in final assembly and should be shipped Monday according to what Chris told me.

You still don't have your grill Mike? Have you touched base with them to see if somehow it got misplaced or ????

Michael

Mine should be going out Monday as well.

I have touched base several times and I keep getting promises. Over the last month I have sent several emails, online chat and made phone calls. The last time I talked to Chris I was told that it would go out Monday 12-31-07 or Wed. 1-02-08. Since I have not received a UPS tracking number I doubt that it has been shipped. :(

I wonder if technically my warranty can even start since I have not received what I paid for.

roughly, how many days from "in paintroom" till delivery? my pair of A7s were ordered on 11/30 and went from awaiting woodshop to box under construction on 12/27. on 01/02 they went into the paintroom. I still have "final assembly and testing" then shipping.

so any guesses? i'm hoping they will be done and shipped this week. Chris thought maybe by 1/3 but that day has come and gone (yes, just an estimate, not a promise)

mjg100: is your A7S the first? Chris told me my two are the first pair ordered and they are numbers 4 and 5. now that you've had it for a month+, and the honeymoon is over, any more thoughts / impressions about your sub?

Yes mine was the first. I like the sub very much. It is a good sub for music and HT. I use mine 90% + for HT. I have my sub set up at the front of my room near the middle. The speaker plate on my sub is in the same plane as my other front speakers. There are some pictures of my set up, with projector screen up, on page four of this thread. The projector screen pulls down in front of my TV. I have been waiting & waiting & waiting on my grill to post some screen shots.

As far as delivery from the time sub enters paint room, mine was around three weeks. My sub had to go back to paint room again after final assembly. I went back and checked. I ordered on 10-13-07 and received my sub on 11-16-07.

Just a heads up though, there was no tracking number on the grill when I got mine (yeah, have grill... no sub though).

It's quite possible that the grill did indeed ship and you'll simply be surprised when it arrives :)

I had the 1st production unit, but the 2nd actual A7s... but now someone at FedEx has it I bet. Ah well, still eager to get a sub back in the theater... without any bass life sucks!

wait. it took an additional three weeks AFTER "in paintroom" for it to be delivered? oh, how my hopes are dashed...

anyway, should be still well worth it.

My sub had to go back to paint room do to damage that occurred during final assembly and there is also the time for shipping.
