Derek, if you're not in a rush, consider waiting for the concept speaker Magnepan is working on, the "Dual Dipole". It consists of a 1' W x 6' H midrange/tweeter panel coupled with a 1' x 3' H triangular OB/Dipole sub. Each sub contains 8-6.5" dynamic woofers, the woofers self-powered and DSP-treated.
The catch is, the Dual Dipole is currently only a prototype design being considered, and may never actually make it into production. Wendell Diller is on tour with the speaker right now, demoing the speaker at Magnepan dealers across the U.S. and Canada.
