-s.k.'s right.  I used to always opt for a little larger than recommended box size;  to get those real low frequency notes, which always worked, but couldn't put as much power to them.  now, i really like to thump it hard sometimes, so i stick closer to mfgr's recommendations.  if it's not low enough, i just stuff it with some poly-fill, and that usually brings back the full sound.   also, if i am building  box for myself or a good friend (not just a job), i always line the box with several layers if fiberglass- hits so much harder.  that plywood might work good, too.  i have also built boxes with 1/2" mdf, then threw 3-4 layers of fiberglass on the inside, they were rock-solid.

Okay I got a question about the air space for speakers when it says that the air space recommened is .8 - 1.5 cubic feet for the speakers is it better to get a box that has .8 air space or something close to it or 1.5 air space.  Also how would you calculate the qct of a speaker box becasue I have two infinity kappa 12.1 in my truck with a box that has 1.4 cubic feet but they rated for 1.0 cubic feet should I down size my box to where the air space is closer the the recommended.

bigger the box the better low end response at the cost of power handling.

Smaller box the tighter the bass and higher power handling.

You can enter your box into WinISD and it will tell you what qtc it is
