2x6 - Congrats on the order! The worst part was stripping 40 wire ends. You also have to pay close attention to making sure you follow from DSP - Interconnect to amp - speaker wire to proper input. I did it one at a time all the way through - the last thing you need is to hook the woofer output to the tweeter on the speaker.

Mojo - the speakers are 31 inches from the back wall and 24 inches from the side walls. The rear baffle's angle is out.
