post #481 of 865
Just thought I'd post an updated picture. I've change out the TV to a 60" Sharp and de-coupled my L & R from the subs by placing them on some foam pads.




Sorry about the glare.

Are you having to run boundary compensation for that center channel?
post #483 of 865
Has anyone taken the non powered pedistals for the 8200 speaker and have added a sub to them....meaning to attach a driver and amp? I have a space problem and don't want to rebuy the pedistals.

Or better yet, does anyone have a pair of powered pedistals that they'd like to swap for non powered plus some cash.

I don't use the boundary compensation because I have Audyssey Pro. The TV is actually about 8" behind the center and the center is at the front edge of the cabinet it is on. With all that being said I do have a hump from the center at around 100 hz that Audyssey compensates for.

I've tried doing measurements with BGC both on and off and it doesn't seem to correct much at all where my uncorrected center hump is at so I just let Audyssey do it all.

Thoughts, and do I really need to get their best?

Thanks,

Just to clarify, the IWTS-30 LCR is an in-wall, not an on-wall. For a 5K+ cubic ft. room, you definitely want the "best" in-wall AT makes. You also want to use the IN-BOX 30 LCR backbox. The speakers are not THX certified without the backbox, and you'll lose significant SQ without them.
http://www.atlantictechnology.com/up...LCR_manual.pdf

Alternatively, I built backboxes to use with them, based on AT's recommendation of 1 cubic ft. internal volume, (which is approx. the internal volume of the IN-BOX-30 LCR.) This is fairly easy to do in new construction. It's harder in a retro-fit, but it can be done.

If you rreally want an on-wall speaker, AT makes this system, although it's not THX Ultra2 certified:
http://www.atlantictechnology.com/default.asp?NodeId=56
Even though AT rates them for Medium to Large rooms, (2,500 to 5,000 cubic ft.), I'm not sure they would have enough output for your room. However, in another thread, it was suggested that 2 sets could be used in a couple of different mounting arrangements:

That's a nice upgrade from the Peds I can only dream about a dedicated room with the 8200e's and three Submersives. That has to sound amazing.

There's a screaming deal on a demo set of 8200e LCR & Surr on audiogon that just went up today.
post #489 of 865
I'm getting the 8200e's for my HT. I will have a 7.1 setup.

Now I'm going through the "what amplifiers do I need" question. My HT equipment dealer has suggested the Denon 4810 AVR (145W per channel) with nine channels on board and bi-amping the front L/R channels. Opinions on this idea welcome.

I'm also intriqued with a Onkyo 5507 pre-pro with Emotiva amplifiers setup. Should I be looking at nine channels so I can bi-amp? Is there any kind of big gain with this setup? How many Emotiva watts per channel should I look at, equal watts for all channels or more for the fronts? Is this a substantially better setup then the Denon 4810 AVR?

Thank you.

I'm interetested in opinions on how the 8200e's and the 4310 might play together in my 16'X19'X9 1/2' room?

Thank you.

Your room is almost 6,000 cubic feet. I strongly suggest the most amplifier power you can afford. Receiver-based amplification will be marginal at best, especially if you intend to listen at anything close to "movie theater" levels. I'm driving my 8200e's with an Earthquake Cinenova amp, (~450 wpc into 6 Ohms.) My amp will also "double down", (or double it's output into half the impedance. My room is 3,800 cubic feet and highly damped with acoustic absorption. My amp will have 3 - 4 dB of headroom over the Emotiva 200 wpc amps, (which will have ~25- wpc into 6 Ohms, but will not "double down".)

Here is a calculator to help you figure how much you need:
http://myhometheater.homestead.com/splcalculator.html
Use 1 speaker and "Away from walls" to see what each speaker will do. Then use as many speakers as you'll have, (7) to see the effect of the addition of all the speakers.

Full Dolby Reference level is 105 dB from each speaker.

Craig

PS. Did you decide on sub(s)?

I have to agree with Craig.

Being a dealer for AT, DENON, ONKYO, Earthquake, W4S, ATI and such, I would also suggest the higher amperage and quality amps like the CineNova and Wyred 4 Sound. That is what I get my clients for speakers that love power, and the 8200's DO Love Power

The smaller and lower amperage 200wpc amps and especially the AVR amps will not be able to keep up in larger rooms.

Craig,

How did you get 6000 cubic feet? I get 2888 cubic feet (16X19X9.5) am I doing something wrong?

My dealer suggested a SVS PB-13 Ultra sub.

Thank you.

Sorry, you're right. I was using 16 x 19 x 19.5. I read it wrong. 2,900 cubic ft. is correct. Is it a sealed space, or are there openings to other spaces?

If the space is sealed, you may be OK with the receiver. Will your dealer let you try it out to see if it's enough?

In any event , the pre/pro with an outboard amp is a *better* solution, if the $$$ work, (IMO).

Yes my space is sealed.
post #495 of 865
Is bi-amping a good idea with the 8200e's?
post #496 of 865
Passive bi-amping? No. Little to no benefit.

Active bi-amping with external crossovers? Possibly, but it requires 3 amps per speaker, disconnection of the internal crossovers and, of course, the external crossovers. If you want to do that, just get Seaton Sound Catalysts. Mark Seaton has already done all the work and the cost would likely be similar:
* Internally powered, tri-amplified design.
* Three (3) ICEpower channels of amplification with 24-bit/96kHz DSP executing the crossover design and response contouring.
* 300W powering the coaxial 1" Neodymium compression tweeter
* 700W powering the 8" midrange (coaxial with tweeter)
* 1000W powering the pair of 12" sealed woofers.
* Galvonic isolation of XLR inputs.

How are you going to wire 3 subs so that sound arrival time will be in phase?

UPS delivered my new Atlantic Technology 727 in-walls today. I ordered 3 for the front L/C/R. L & R will be beside my screen. C will be behind. I got a great deal from Atlantic's B-Stock inventory. I'll be keeping my eyes open for a good deal on surrounds.

I read through the entire thread today and there seems to be quite a few of you with 8200s. Not sure how many AT in-wall members are out there. For those of you that did go in wall, I'd be interested to hear which surround you selected? Bipole for sides and back? Or bipoles on the sides with direct firing models in the back?

My back row is only 15" from the back wall so I'm not sure which would work best for rear surrounds. I'm leaning towards bipole for the sides (IWTS-14SR).

Glad to join the family. These sound awesome.

I went with AT IWTS-30's and matched them with the 8200e Surrounds (Di-Pole/Bi-pole). I have a 7.1 set-up and have put them all in di-pole mode. For 5.1 you would definitely want to go di-pole.

Anyone have any experience or thoughts on the Atlantic Technology FS-7.0 Soundbar and SB-800 Sub? They recently got a great review at Home Theater Mag and seem to be a reasonable compromise for rooms not configured ideally for separate speaker surround sound.

Here is the HT Review:
http://www.hometheatermag.com/compac...nd_sb-800_sub/

Our Panasonic TC-P65V10 is in a 19x24 open area great room with vaulted ceiling, a full window wall and hardwood floors. Not excited about running separate speakers either outside or inside the walls without a reasonable expectation of getting true surround sound. This Atlantic system seems like it might be a good compromise, especially since neither of us are true audiophiles. We do want to get crisp intelligible voice and reasonable surround effect with good bass and rumble effect for our movie watching.

Any experience with or input on this system is appreciate!

This pic will give you an idea of our room challenges for sound:

post #502 of 865
It's a fairly new product. Probably not many users yet. Try calling AT and asking for Tech Support, (ask for Steve if he's available.). They can tell you whether it will work well in that space.

I checked with the seller, and they are the older (non "e") versions (he's using the wrong stock photos). Still a decent deal, though.
post #504 of 865
The cool thing about thos 8200 (non e) SR's is that they are bigger and ha e bigger drivers than the 8200e SRs. If I were looking for surrounds to match an 8200e or 6200e front end I would inquire about just those surrounds.
post #505 of 865
I've owned AT's 350 THX for 12 years and still love them. I currently have them coupled with a Snell ICS24 THX Ultra2 sub and B&K 505 receiver (display = Sharp 12k PJ).

I will be moving in the next 5 months and am considering selling everything and starting anew (so I don't have to move said stuff ). Sadly, I obviously wouldn't be able to get much money at all for this system - virtually nothing when compared to what they're worth to me now performance-wise.

My question is, would the many thousands of dollars I would need to spend on an 8200e system really be worth the upgrade from the 350? Or would that money be better spent towards a new receiver and/or projector (and keep the 350s)? I briefly considered the 6200e but decided if I'm going to put any money towards speakers, it'll be the top dogs. I appreciate any insight from those who have experienced both the 350 and 8200e systems. TIA!
post #506 of 865
I've had the 350s, 450s and for the last several years, the 8200s.

In a large room (6,000 cubic feet) I think the 8200s is a good fit. I tried my 450s before upgrading and they just weren't enough in terms of sound quality in such a large room...and I don't typically play my system all that loud. I really am talking about sound quality and not spl.

Something else you may not have thought of us that if you do go with an 8200 system, you are also likely to need either a more powerful amp or receiver.

I think if it was me, it would depend on when in my life I would be doing this. If it was back when I had to be more careful with what I spent, I would at least try the 350s in the new home. As you said, you're not likely to get much for them. You may find that you'd rather just keep them than to sell them so cheaply. If its during the time of my life when I could more easily afford the 8200s, then I'd go ahead and sell the 350s for whatever I could get and be done with it.

I don't know if anyone else would agree with me on this point but when I got the the 8200s I went with front mains for side and back surrounds too. As you can imagine, that ran the cost up but I have no questions about having as close as possible to the same sound coming from all 7 speakers.
post #507 of 865
^ Excellent advice from JimP.

Jim, you have the 8200's, not the "e" version, correct? Do you have the 8200 Ped Sub's in each of the 7 speakers? If so, are you running all 7 channels as Full Range? Do you have LFE subs in addition to the sub "peds"?

Do you know anything about the room you'll have in the new house? I think that will be one of the biggest factors in the decision making process.

I have a room that is about 2900 cubic feet and I'm going with the 8200e's. Both my AT dealer and one of the senior technical people at Atlantic Technology told me they will be great great in my size room, hope they are right...Going to pair the speakers up with a Denon 4810 AVR and SVS PB13 Ultra sub woofer in a 9.1 set-up (adding Height speakers to 7.1), hope I'm doing the right thing? I had the AT 450's in my prior HT and they were great.

With those pieces, I don't see how you could be doing the wrong thing!

That system will rock your room!

I have no doubt the 8200e's will be terrific in your room. Are you planning any room treatments? Audyssey MultEQ XT can do a great job in many untreated rooms, but if you start with a well-treated room, Audyssey can do a spectacular job of optimizing the system to the acoustics.

The 4810 is not a THX receiver. That's not a problem, per se. However, I would check with Denon to ensure it uses crossover slopes that are compliant with THX spec's, (2nd order High Pass/4th Order Low Pass @ 80 Hz.) Your speakers are designed to work best with that crossover set up. Many receivers use it, even if they're not THX certified.

Good luck, and enjoy your new system!
