I'm looking to build two boxes for a pro audio setup, 4 18" subs each. I'm trying to duplicate a design by a company called Electro-Voice. They used to make this box that was a 4th order bandpass with 4 18" subs...one of the best sounding, most efficient, cleanest boxes I've ever heard. The box looked fairly simpple, more or less a cube with the subs facing one left, one right, one up, one down, 4 ports one at each corner...well I want to build that same box but with some better subs, and I want to build it to the specs for those subs...so any ideas?
