So wait, staggered studs are 6" on center or they are 2x6?

How about building a box below the screen that allows you to mount all four drivers in your room without cutting concrete? The box would be 5 sided with the opening against the wall. Then you would just have to open up the drywall behind box and seal the edges up.

So something like the attached images and nail it right to the concrete? That would relieve me of pounding out a notch in the concrete, but take up a lot more room in the back room. I guess it depends on how hard it is to pound out the concrete.

Re: Christmas Build

Hmm. actually I was thinking something different. Imagine a sealed box that sits just below your screen in the HT room with the 4 subs in an array just like you wanted it. That box would have only 5 sides and the open side would be attached to the wall and sealed. The gypsum board behind the box and also in the adjacent room would be removed and you would seal up the three sides within the wall to the footer. You wouldn't have to cut all the 2x4s either.

Another way to think about it is like you are building a manifold. Except instead of an "innie" (belly-button reference) you are building an "outie". And instead of opposing drivers you are doing a line array like you originally wanted.

Sorry, I'm not a a computer with sketching software...

Re: Christmas Build

For the miniDSP problem, I believe there is a jumper that can be moved to change input sensitivity.

Ah, I get it. You are talking about basically moving the line array further into the room to avoid the concrete and cutting of the wall. Interesting. Did not consider this, but it could really work.

Tried that and it only bumped output a few DBs across the spectrum, but that only helped a tiny bit. This was actually using the MiniDSP with my old sub using xlr connectors. I wonder if connecting it up to the Beringer will help fix that or if it is only an issue between the preamp and the MiniDSP. I am hoping I don't have to get a clean box or something like that. If so - any recommendations?

If I ditched the MiniDSP and did the 1124, does this issue disappear? The MiniDSP is soooooo nice and easy and quick and many other advantages, but 1124 does have some definite advantages over it. Such as the ability to load new filter settings at the without a computer. So I could have the late night setting and the setting for when the wife is home and when she is not.

Re: Christmas Build

I did get the drivers - 18" never looked bigger. Huge and heavy in person. Here are the unboxing Pics for FiCarAudio IB318. The last one is on my current subwoofer - makes it look girlish.

Re: Christmas Build

One box was damaged, but the driver was ok. They should look into beefing up their packing a bit.

Re: Christmas Build

For reference, here is the basic line array spacing.
