The 10" deltas use a 10.75"deep box but I think you need some space between the screen and speaker. I bet you could make a shallow box but make it taller to get the same volume.

What about opening up the wall as well to get more depth?

Tuxedocivic has an in-wall build, but I don't know if he has a thread specifically for the speakers. Here's a thread with some pictures, though: http://www.avsforum.com/t/1446510/help-with-room-treatment-with-diy-mentality

I've got a thread started on diysoundgroup and have measurements coming in a few days. I have 2 cross overs whipped up. One for me and one for the public biggrin.gif

In your case you could do what I'm doing even if it's not in the wall. Just build a 6" deep internal box as large as you can. Divide it into three for each speaker. Alternatively build it into the wall, but don't let it stick out more than I'd venture to say 1.5". Feel free to ask question.

Oh and it's VERY good biggrin.gif

I have not upgraded speakers in like 15 years, so I think it's time! If I go with acoustic screen (a woven screen), I'd like to not reduce the useable length of the room by more than 8-10 inches. That makes for a very shallow speaker box. I can, however, go way tall and wide on the boxes if necessary to get proper volume. I just thought a pair of 8's would be good for a shallow speaker depth.
If anyone has any experiences to share with SEOS project mounted on-wall and/or used with a woven screen, please share, thanks!



I just finished building an AT screen out of spandex, and I'll build 3x SEOS12 speakers sometimes soon, I hope. The center speaker would go behind the screen but my L&R would sit beside the screen. I love the look of the TD12M and like to look at the speakers while watching movies. LOL

The screen built was around $100. Not too shabby.

You might need to find a better selection of movies smile.gif

Is the finish choice on the SEOS important with an AT screen ? Will the glossy finish be a problem with an AT ?

I have gloss and can't see them.

Reason I am asking is that would like to move to an acoustically transparent projection screen, and I will have very little space between the screen and the front wall. I will need three very shallow cabinets, so I think anything >8 inch woofer might not be possible. The 4 woofer designs look nice, but just wondering if a 2 x 8 has been considered.

Note that the SEOS+CD is 6" deep; there is at least one 12" driver that I know that is less than that - JBL 2206 at 5" D.

I felt tempted to see how my Oneida wall measures after this discussion so I got off my butt and did it. Measures great. I'm not surprised since it sounded so good. Really happy. Will update my thread with details later.

Good to hear tux, looking forward to your measurements. I just ordered my omnimic, so I'm very excited to measure mine.

Oneida wall was supposed to be on wall. Auto correct got me tongue.gif

Nice bunny. Please post what you get.
post #6313 of 9854
Will do. This will be my first capture of in room response with the new speakers, so I get to see all those uncorrected dips and nulls. Can't wait! lol. Outside of improving my listening room, my main objective for this purchase will be to obtain the frd and zma data for my surround build. Should I invest in the DATS system? I'll be using PCD.
post #6314 of 9854
Thanks for all the feedback on the on-wall or behind woven screen. Sounds like I have a few options. brian6751, I could go in-wall, but I'd rather not, as it is an exterior wall, and there might need to be some re-wroking of studs to have clearance.

this morning i was scanning drivers and thought that a super budget sattelite could be built around the seos12 and a pair of aura ns6-255's.

they have a really smooth frequency response, are underhung, and are only $9 ea. the only problem that i see is the impedance would be 4 ohms for two.

http://www.parts-express.com/pe/showdetl.cfm?partnumber=299-030&utm_source=google&utm_medium=cpc&utm_campaign=pla&utm_term=%7Bkeyword%7D#

in 1 cubic foot sealed, a pair have q=0.8 and -3db at 80hz and 93db 1w1m sensitivity. this is what i was thinking:



then i noticed that they look quite similar to what cuzed employs here, but i don't know if they are the same or not.

There has been a lot of talk about those drivers. There was even talk about making it into a flat pack, but it died, because availability of those drivers is probably going to be limited. It does make for a nice budget design.

LTD02, there is a design for that called the Daniel. Cuzed2 is building a variant of it to get 8ohms down below 200hz or so at the expense of size and 2 more drivers.

To all, most of the SEOS designs are over on diysoundgroup. If they were all posted here it would be kind of pushy towards all the sub builds and other types of speaker builds. So if you're hunting for a specific design go to www.diysoundgroup.com/forum/ because even there are quite a few more than just the kits listed for sale on the site. Like the Daniel, my in wall delta max, I have an eminence alpha8a SEOS build that $150 including the entire enclosure or $120 with just the baffle, MTG-90 has the 2226 design there, and he has an 18sounds build I think. Plus some smaller things. You don't have to be a member to see them, so worth surfing around to see what there is.

Parts express has 1,737 of those drivers left. Thats enough to build 868 speakers if you were to use two speakers in each cabinet.

I stand corrected. I just remembered someone, thought it was Bill W. saying availability was the reason this was not considered as a flat pack, but I could be wrong there also. smile.gif

but a lot of (most?) designs use 4 per speaker. Most builders make pairs or triples , which would be about 200 builds total - for a number of different designs I'm aware of. Not to mention a lot of buyers who pick them up just because they are 9 bucks per for a quite good woofer. Last year at this time they had over 6 thousand. I'd be surprised if there were any left by April.
post #6321 of 9854
And they're also used for Stentorians, those are 6 per speaker. Tempted to stash a few away to build Stentorians one of these days.

Do it. Do it now. Don't listen to that voice in your other ear. Just do it. You know you want to and they will sound sooo good, too. So, go ahead and do it.
Hehehe.

"there is a design for that called the Daniel."

thanks. i didn't see it in the "seos speaker designs" area.

i really like how the designs are listed according to the drivers used and not a bunch of random names.

for example, i know exactly what "JBL 2226H + DNA-360/SEOS-12" means.

i'd have no idea what it was if it was called the argento or the scarto. :-)

I like the way you think PI - and of course you know your build was a good part of the desire to want to build them. Now if I can just have you talk to my wife and explain why I need more speakers than we have rooms in the house. rolleyes.gif When I start fantasizing about the next project, I suddenly picture Richard Dreyfus sculpting mashed potatoes - why is that...

That one's easy--just build more rooms! Like that crazy Winchester lady who kept adding rooms to her house, except if it's for more speakers, it's reasonable!

Wishing Everyone here a Belated Merry Christmas, and the best for the New Year.

I have also updated my Big Mal build thread. The latest is posted here (post#51)
http://www.avsforum.com/t/1440063/diy-seos-for-ht-upgrade/30#post_22729333

And I leave you with a question:
Should I put round-overs on the horizontal edges of Big Mal?
Here is a sample of some round-overs on a test box, what do you all think?
post #6329 of 9854
I round over all my edges, I like the way it looks, and it seems to be less likely to show any dings.
post #6330 of 9854
Hi all, been lurking for a while. I have 3 SEOS 12" with the 360s. Getting ready to order 2 Tempests. I' m planning on going with the original MAL for center. Have those been kitted up yet? With that small of an enclosure I might even be interested in a flat pack. Anyway my real Q is about cabinet making. I'd like to get the box looking good for SAF so am thinking of using BB and mitering the corners. Will that be strong enough? I might be able to biscuit joint the miters using the smallest biscuits. Also I'm thinking of finishing them in black stain (like some Polks I have). Anyone have any experience with that? Gel stain and a thin coat of water based poly?
