i tried to build it exactly like the plans, every piece of wood was in there, not perfect, but as close as i could. i dont own router, so i mounted the subs to a 'removeable' baffle (like in the plans, its easy when you actually do it) and then i cut the hole in front of the subs just a little bigger so they poked thru.theres some other weird bits of wood here and there that require some thinking and make no sense, till you hear it.
ive als built several dbs (10 and 12) wedge, wo, hwk, etc etc, but the wo32 is
SOMETHING ELSE. its sooooooooooooooooooooooooo flat, 20 hz is exactly the same volume as 80, its really weird when you listen to music you know really well and when the low notes come, they are right there, solid as a rock, with zero loss of output all the way down to the lowest notes
get your wo32 finished, as close to the plans as you can, you will love it more than any subwoofer you have ever built.
house only, not in a vehicle.
that pic ^ is just a pic of a sub i thught youd like

i used 'dayton series 2' 10" subs in my wo32.
i too am a speaker freak
