Lol!  Speaker design is something that demands precision and knowledge.
Sounds like you have both!  I'd love to see pictures of this box :P  I need
to get a decent monitor system for my production studio.  Right now I'm
using a couple of small MA-8 satelite speakers (roland) with the bass rolled
off and a Samson sub in my turntable studio.  But I think it lacks mid-low -
For my main studio I would like to get as accurate as possible. . .  I've
really been eyeing up the Mackie 824's, but I won't have the dough for a
while.

Any ideas?
