A couple of IDQ 10's should rock the house with that airspace.
I've already got two MB Quart shallow 10"s (RSH254) that the box was built for... for now I'll to stick with those.A couple of IDQ 10's should rock the house with that airspace.
I think to increase the volume, even by a little bit, I may build a couple of mdf rings on the outside of the box to mount the subs to.... raising them out of the box a bit.

You can also try mounting the sub face down with the back up in the air to see if it will play lower notes with more authority![]()
I think you'll be fine, but you could try using insulating fiberglass (loose) if polyester fiberfill isn't available. If you're concerned about bits breaking off can causing itching (or getting into the sub's motor), staple some jersey material or speaker grille cloth over it.As it turns out after filling the box with water to measure its volume, I ended up with approx. 27 litres... which is just under the 28.32 litres that make up a cubic foot.
You could try using some 1" dowels and an extra layer of glass to cross-brace and stiffen the enclosure. However, I suspect that there might still be noticeable vibration - and the volume of the box would be decreased.I think one of the major problems with the box currently is what Brian Steele is hinting at.... I could use a lot more glass to stiffen things up. Currently there is no bracing at all, complete fibreglass.
The divider will help to stiffen the enclosure even further.I know I asked this before but while i've got your attention, can you guys say if placing a divider or chamber separator down the middle of a sealed box is necessary or not? I'm thinking 'not' but will take a more educated opinion if it's out there.
Gee that's crazy.... I would not have thought there would be that much flex but I guess I'm basically building a sealed lung that's trying to huff and puff, so it does make sense. I think because of the strange size and limited space inside the box I may just go nuts on the fiberglass instead of adding dowels or bracing inside. I will take pics and update this post.You could try using some 1" dowels and an extra layer of glass to cross-brace and stiffen the enclosure.

I really appreciate all the advice and look forward to success because of it! Thanks!
You would be FAR better off building glass "spines" inside the box to brace it.. you'll need less overall glass and a few well placed spines can stiffen things considerably.. You can use a dowel rod if you like, hell, i've used pencils.. all you need is something to hold the shape.. you could use some masionite, and just cut it into 1" wide strips.. sit on edge and glass into place..Gee that's crazy....
