I am tasked with building a sub into the floor of my theater room. The room is 21 (l) x 15(w) x 9.5(h). The raised floor takes up the back seven feet of width, and is raised by a mere seven inches. I am wondering what sort of problems I might encounter.
Ideally, I would like to build a down-firing, vented enclosure with the vents aiming outward along the 'stair' face. I would then cut a decent sized rectangular slot to allow for driver air movement - also along the face of the stair.
There are several items of concern. The box shape will need to be _very_ shallow and long. A couch sits along this step face, and I would like the vents (two) to be just outside the couch edge of about 6 feet. If the enclosure would be too big, I could always make two of them, or vent it on just one side (and move it to one edge).
A five inch depth would give me about two inches of air in front of the driver. This should be enough, but is probably pushing it. I would also possibly need to recess the magnet into the box structure (IE router a section down a bit) to get extra depth.
I have looked at the new SB Acoustics SB29NRX75-6 10" driver. ~ 5 inches deep. A few dayton models will also fit. Any recommendations? I am really looking for quality/accuracy. I don't need to rattle my foundations - but that would be OK too.
Thanks,
Todd
