I'm sure something like that could be worked out, but that would double the cost of the low pass network, and at least part of the high pass. I'm really just going to be looking at the CD's...

Very true. I'm about to find out if a 1.4" CD is going to be capable enough to make it work. A 15" is always an option if not. Right now I'm in for $270 on the WG/CD combo
