woofer called for in wo32 & wicked one:
DHM108B: Qts: .618, Fs: 40.8 Hz, Vas: 1.87 cu. ft., 90.5dB SPL
what ya have:
12W7: Qts: .0.482, Fs: 27.2 Hz, Vas: 12.33 cu. ft., 86.2 dB SPL
not too close
I think I'd "mod" it by trying to ebay the 12W7 and up-grading the driver to one with the right electrical/mechanical specs to start with, so the box will work as designed.
Then I wouldn't have to make it two inches taller & cut it in half front-to back & wonder why it didn't work... >:( :(
Then...
Didn't Steve say the wicked one worked better in vehicles than the wo32?
