Since my Tumult has been reduced to music only, i'm looking to a 13w7 to use as the main theater sub. I plan to run them both together (with the tumult at a lower level) while watching DVD's.
My only concern is that the enclosure will have to be somewhat larger than my current one, which is about 3.5 cu.ft. internal. The 13w7, at 6 cu. ft. internal (22.75 x 22.75 x 21.125), models virtually the same in response and output at 20 Hz as the Tumult does. A 24" cube (8 cu. ft.) is about the largest i'm willing to build, hence the Q problem.
The Tumult box has a Q of around .65 and sounds quite nice but for the 13w7 i'm looking to get down between .57 and .6 damping.
I used 1" foam lining and polyfill from wal-mart for the Tumult box and i'm wondering how much i will need to drop the Q from .65 to .57 for the JL box.
Thanks all. :T
