Around a 35hz tune

I would love to see something like this added as the higher end / reference "flat pack" ... maybe even tune it lower with some longer ports or via adding a second woofer (2 10's vs 2 15's) ... perhaps this is too much for most of the diy market to be reasonable ...

Do you have access to a webserver (your own, friend's, company's, etc.) that you can upload whatever audio or video file you wish "cast"?

If yes, PM me and the hand holding can commence ...

My first post here and excited to start my DIY home theater!!!

 

A couple of questions as i really would like to use the Alpha 8 Minions as surround speakers with the Fusion 15 Sentinel as my LCR. I currently am using a pioneer VSX 1122 receiver and it sounds great even though id does not eq the sub and i have "Best Buy" type Sony speakers.

 

I really would like to stay with the pioneer as the MCACC seems to work great and I am leery of upgrading to and Audissey XT32 based receiver for now. The lowest crossover setting on the pioneer is 50hz which i think would be great for the Sentinels but the Minions only go down to 55hz which I suspect is room dependent too. Really would like to run the Sentinels as low as possible for that mid bass slam i hope to get!!

 

1) Would the minions be able to handle the 50hz crossover ??

 

2) Could the B&C 8" speaker be upgraded to one with a lower F3 point??

 

3) If I ran the Sentinels full range, with the surrounds at 80hz, would this be a better setup than the single 50hz crossover setting for all speakers??

 

Just for info sakes, will be starting this diy project first with single 4 cubic foot flat pack subwoofer with UXL-18 driver and behringer nu6000dsp or ep4000 amp. My living room area is approx 25 x 14 x 9, open concept  with a kitchen/eating area of the same size next to it. If all goes well, I will finish the basement below my living room/kitchen into a dedicated home theater but i will start simple for now...

post #8707 of 9852
1. Not if you want them to keep up with the sentinels.

2. Not without a XO change. And the woofer would give up sensitivity to do it.

3. Yes. Much better idea.

What makes you think the sentinels should be crossed at 50hz? Have you measured your room? I guess I don't really understand this fascination with mid bass slam everyone craves. I think people get these monster subs with wicked house curves and wonder where the mid bass went. :shrug:
post #8708 of 9852

Has anyone used the EOS-6 in a build yet?

 

If so, will it cross nicely at 1kHz to1.2kHz with any of the DNA horns?

 

I haven't been able to find any builds with this horn.

 

THANKS!!!

post #8709 of 9852

Thanks for the info...

 

I figured that crossing at 50hz would be good as the Sentinel spec is from 40hz to 20khz, but yes i should have added that I will be ordering a umk-1 mike (possible mini dsp too...) and using REW shortly to run measurements before starting on this quest.

 

I want the UXL-18 mainly for ultra-low extension to 10hz if possible with the sentinels taking over around 40-80hz depending on room measurements. The total space with open concept is approx 6000 cubic feet which is quite large and it will be over an empty basement with hardwood floors!!! Not very acoustic friendly but the SEOS design hopefully will compensate.

Three sentinels should have better mid bass than 1 uxl-18 driver but will see once i measure the room.

 

Like i said, i will start off slowly and get the minions and the big 18 subwoofer before getting the Sentinels, so i can see how this SEOS design will play out in my room.

If i do get the Sentinels, I will want to power the LR with a crown xli/xls amp in full range of at least 500 watts rms in which case I will be concerned about excursion below 40 hz...

I think the minions will surprise you. Not with bass , but the overall sound.

2000hz Minimum Recommended Crossover Point

As stated on the other forum where you asked, you'll need a SEOS-12, maybe SEOS-10 to play that low. You may get away with lower with a smaller guide, but don't count it sounding good.
post #8712 of 9852
It might do 1khz with a ring radiator dome and SPL limits around 100db at 1m and will require modification and won't hold directivity that low wink.gif The DNA-150 won't go that low. It just won't extend that far. Most 1" CDs won't afaik.

I've crossed a lot of domes at 1khz using waveguides, but there's the limitations I mentioned. So it depends on your goals. What are you trying to achieve?

You know how thay say a little knowledge is a dangerous thing?

That's about where I'm at.

I've had conversations offline with a designer about modifying one of his designs that uses the RS28 to work with a compression driver and waveguide.

He mentioned the 1kHz crossover point, and I was surprised to hear the CD/waveguides didn't cross that low.

After reading up on the driver specs and reviewing some of the designs that are already out there, I'm realizing the 1kHz crossover point is lower than typical, even in a waveguide application.

Make sense?
post #8714 of 9852
I'm not sure I'd say 1khz is lower than typical. What's typical? If talking flat baffle domes, ya it's low. But if talking robust CDs with 15" waveguides, it's pretty standard. So depends.

You should design a speaker based on the performance criteria. Not some desired XO point. If you really want to use a small waveguide and cross over that low (for who knows why), try the SB29 ring radiator in about an 8" waveguide. It'll do it fairly well actually. But you won't have directivity by 1khz.

The shipping container is suppose to be in Cincinnati ready for delivery. I'm just waiting on US Customs to give the green light and release it for delivery.

I'll get photos of everything once it arrives.

Awesome!

Good luck

carp, were you able to confirm the CD in the 212?

Also, any idea what the mid-woofers are?

Thanks,

post #8718 of 9852
Having had my alpha minions for a few days now I find myself listening to music louder then before. I used to listen 80-90db's since that seemed to be the sweet spot of my speakers. Over 90 and it was hit or miss depending on the song. Now, my loud listening session of an hour or so the minions can push 90-105 dbs without straining. I am 10ft from the speakers and at the end of the intro for money for nothing the roar was 103db's for three seconds from a bookshelf speaker. Felt like I was at a concert. I know concerts are louder but seemed concert like.

Now I know at gtg with JTR and seaton speakers they push 120db's (can't imagine) but my question is how loud in db's with spl meter do you listen to music ? This is just a range question, not an exact number. Say 70-80, 80-90, 90-100, etc . Other times I put xmas tunes on at 60 db's so I am not listening super loud that often. Interested in hearing from people who frequent this thread. I know this type of question has been asked before but I am following a lot of build threads with diysoundgroup right now and just curious.

For movies with my wife we tend to watch at 85-95dbs with peaks hitting 105-110 . This is with C weighted spl meter. Again I am not looking for nuclear fission calibrated techtonic accuracy in measurements. Just ballpark. The thing that the clean loud minions have done for me is have confidence that I am not going to blow a tweeter or a woofer.

No, we always end up running out of time - both got into trouble for "playing" too long as is. smile.gif

I've thought about doing it but it makes me nervous to start taking the speakers apart. Yes I just said that in the DIY section. eek.gifsmile.gif

Oh, and sorry, no I don't know what the woofers are either. I am officially no help.

Customs fees, duties, customs entry fees, bond fees, more fees, extra fees.......$2,478.32 over the cost of shipping fees. rolleyes.gif

The container is indeed in Cincinnati but I just got that bill today. The broker, forwarder, or what ever is in California (91748). Tomorrow I'll do a 2 day FedEx on a cashiers check to get it there quicker. But I don't think they will get the payment until Friday, and for some reason, they'd rather not do wire transfers.

Obviously they won't release the container until they get the custom's payment, so now I'm doubting it will get delivered to my place this week. Bummer. I guess that might mean Monday on the 23rd, but they only leave the container for a day before charging a lot of money to "rent" it. So looks like Christmas Eve will be a busy day of unloading large boxes.....hundreds of them. biggrin.gif

"If they don't have enough mid bass (in your room) and they aren't running out of excursion, just eq it up."

it depends how your limited. if running out of amp, building it into the speaker through higher sensitivity in that region might be a solution. not sure if the under-damping is deleterious sq-wise.

Wish I was closer man, I'd love to help out.

Bummer that they tack those fees up so much, make sure we all pay our part when buying smile.gif

That's true LTD02. If someone wants that midbass kick (aka distortion wink.gif ) then perhaps a 80hz (or there abouts) tune in a large box would be a good idea. Or undersized sealed.

I wonder how many people are referring to midbass kick as those high passed PA systems and when they add their monster subs they end up thinking, where'd the midbass kick go. I think, maybe it's there, it's just flat now because their system extends way deeper. Or they've put a wicked house curve in cause they think that's what they want. If they took out that curve and put a frown in the response right at 100hz, maybe they'd get midbass kick... cool.gif

I tweak my minidsp all the time, my latest curve gets me the best chest kick so far for music (well, not really a "kick" at the volumes I usually listen to but even at these lower volumes you can feel the kick drum in your chest) while still sounding natural - meaning bass notes at different frequencies have the same "perceived" volume. However, I'm sure I'll tweak this response too.

The curve I had before I thought I was 100% happy with music and thought I wouldn't change it, but now I like this one better:







I keep meaning to start a thread that asks for people to post their responses for what sounds best to them for music, that way I can experiment with trying out curves that others like and see if I do too.

Haha, yep! This is what I use with most of "my" music which is metal. However, this is what I use for bands like Pink Floyd that record their bass levels much louder:







Again, 1/12th smoothing. It was harder to get a smooth line than it was with the house curve but I got close. Using 1/6th smoothing it's very straight. Sounds great for Floyd and anemic on most hard rock and metal.
post #8728 of 9852
For me the fun, excitement, and joy is catering my system to my listening needs. I wouldn't need a graph to know carp is bass heavy if i listened to his system. I honestly have no idea why one has 6, or 12, or 18 subwoofers. I may not understand why anyone would want to listen to sub 15hz material , but I can appreciate someone shooting for a goal and achieving it. I frankly have heard (well felt) strong sub 15hz but i don't enjoy it. It makes my stomach quesy. Just like going down a roller coaster which I never do either.

I am guessing here... but I think midbass kick for some goes back to a concert experience. I have only gone to about a dozen concerts but when I went to metallica , acdc, and even rush, I remember the chest thumping bass. I don't really remember (concerts where awhile ago now) deep down sub 30hz bass much. If we graphed the concert my guess is they are running 15-20db louder at 70-120hz then 25hz. Maybe someone here has worked the sound for a concert and can chime in.
