So I've got this little picture up at
with my proposed cabinet idea. I wussed out a little bit with some things, although I think it's a general step up from the recommended kit plans (box with no bracing). I figure it's roughly about 40 litres and it's tuned around 45Hz.
The speakers will always be x-overed at 80Hz, so my smaller than uni-box recommended port size (well by about .6cm) won't make any noise (doesn't pass the red line till 50Hz, at which point the x-over should have that down a good 9-10db), x-max looks scary as well as I exceed it at full power at 86Hz, but then again full power with these two drivers also equals around 120db (and I never get there), more normal listening levels show no problems either.
So how about the box construction, am I losing anything by not using 3/4" bracing. I went 1/2" in a few places to save some weight, although these things will probably be up in the 110-120lb ea. range when they're done anyways.
