After thinking for a while, well, a real long while, my mind settled upon the driver combo. WWMT config, 2x Dayton 7" aluminums for the low end, audax am130z2 mid, and vifa xt tweet. The daytons were chosen b/c of their ruggedness and their low frequency extension. I didn't need to be anywhere under 30 hz, b/c a sub will take care of that eventually. The audax, so I've heard, had nice mids, and wasn't nearly as expensive as a seas excel, nor as difficult to work with. The xt, well, I chose it for the $ and for the completely transparent highs that it produces.
