Do you guys think these subs would do the trick? I want to have 2 seperate actual subwoofers, 1x driver per, prefferably in the smallest box possible as i have space/placement limitations (NO WAF, just a very narrow theater room (11' wide x 20' long).

11 x 20 is not small by any means. These drivers really happening now.

Keep cranking,

Robert

I'm sorry, i didnt mean to imply the room itself was a small space to fill with sound. I meant that the way it is oriented i have very limited places to put speakers, specifically large subs.

Basically its about an 9' ceiling, 11' wide, and 20' long. I have a projector ceiling mounted about 17' from a 118" screen. The dimensions of the screen basically fill up all but about 18" to the left and right of it before you hit wall, and ceiling to floor is only about 13" on top or bottom of screen. So, with having to place my FL/FR speakers in the front, i dont really have any good placement options as far as getting the subs in the corners. In the rear of the theater there is only 1 corner which is where i have my HSU sitting, and next to that is the A/V equipment (htpc, receiver, etc) So, i could in theory put 1 sub there, and the other sub somewhere else that wouldnt be quite as ideal.

I can draw and upload a picture with the layout, if it would help.

I guess my main concern is would these perform in a reasonably sized sealed box? Maybe as a downfiring sub, or something along those lines? I could deal with a 21x21" footprint and height of maybe 28" at most. Would that be sufficient? Or would i risk bottoming out the sub, etc.

Also, how is the musicality / sound quality of these subs? One thing i particularly like about my HSU is how it sounds with music, although 80% of the HT is used for movies or TV shows.

I asked Josh after he tested the drive, and he told me my 3.6 cubic foot box would be ok, but I would have a little rolloff in the bottom and I might need a little EQ. One good point is the power handling will increase.

I just saw this. With smaller sealed box, you get protection from bottoming. Those measures are external with single panel sides?

This is where an AT screen really comes in handy. You have very similar dimensions to my room. I'm a very narrow 10' 8" x 24' x 9'. I had a problem with the corners as well so mine are going in between my center tower and mains in a vertical config.

I am now ready to order my duel SI 18D's but everytime I call the phone number listed on the SI website, it seems to be disconnected. Does anyone know how to go about ordering them?
post #997 of 2212
You order them directly through the website

http://stereointegrity.com/index.php?id=57

Looks like the D2's are sold out

Sheesh, thanks a lot PL. biggrin.gif

Good thing he's after D4's. Better jump on them.
post #999 of 2212
Just ordered 2 D4s here as well.
post #1000 of 2212
D4's are the s**t. They're too hot to handle. That's why no one got any.... can't handle the heat of those babies. biggrin.gif

Now me? I could... yup. cool.gif

Don't blame me...lol. It's all beasts fault!

I talked to Nick yesterday and he said they still have something like 50 of the 18" D4's and plenty of the the D2/D4 15's left.

Wonder when the D2's are going to be back in stock? I'll have to inquire when he drops off my D2's this weekend.

Don't you put this on me Ricky Bobby! I ain't do nothin'!!! Dang, two movie quotes in a row, I have to stop.
post #1004 of 2212
^^ Both of you crazy ba*rds are guilty of depleting the inventory.

Alright, maybe P-lock's trailer load killed it the hardest though. biggrin.gif
post #1005 of 2212
I think between the three of us we cleaned em up pretty good. Did anyone else get eight or more?
post #1006 of 2212
I got 8 and could use some input. Post #988 Bueller Bueller?
post #1007 of 2212
It's best not to over think the bracing. Way too often people over do it and it's really not necessary.

Go for window bracing or just cut one big circle out. It's really more important to tame the panel resonance(s) so spacing out and having wood "bracing" on the walls is all you really need.... yes, mostly. tongue.gif

Thx Scott
post #1009 of 2212
Yep yep, I will not be doing roundovers on my cabinet bracing. I think that is just a waste of time, but it looks good!

Depends what kind of output you are looking for, and budget.
The SI 15" sub is happy in 2.0-2.5 cubic feet, which is a pretty small box, ~ 18x18x18" cube. 2 of those to smooth room modes might be enough for your and meet your goals. Ported box tuned to 18 Hz ~5 cubes

Then again, an SI 18" could be used in a box as small as 4.25 cubic feet. Ported you are looking at 6-10 cubic feet.

Without EQ the VTF-15H will probably be louder at 20 Hz than a sealed SI 18.

Also, I am just getting the funds together for an 18D2 and NOW they are out of stock? I wonder how many months I'll have to wait now?

I just purchased a HT 18" D4. I will be posting up pics during my build process. I am going with a 4 cubic foot sealed box powered by a EP2500

It does, lol and I never mind seeing what kind of work people put into their bracing. Heheh. Often they are their own work of art. tongue.gif

Nice and all but it does nothing to help performance (99% of the time) and once that box is all sealed up it's hard to appreciate it anymore. More time spent on the outside would be best. I should take my own advice.... nah. Black paint. tongue.gif

Nice. Just one? If so, you can bridge that ep2500 and let loose on that baby!
post #1014 of 2212
The first time I put together a dual opposed, it became obvious to me that bracing is doing very little for most folks. 99% of what people perceive as 'box flex' is simple Newtonian physics at work - vibration caused by driver's physical piston movement, not by pressure changes in the box.

Yep just one. Was struggling to find a place to fit the box in the theater room.

We actually changed the phone number today. Didn't realize the old number was still up on the web site. eek.gif
post #1020 of 2212
Any idea when the D2's will be up?

Also, anyone ran a 2 ohm load on 1 channel of an EP4000 or EP2500.. ? Will it be happy?
