This thread has got me thinking seriously about using 2 M2's in my system. I'm currently using 1 vertical M2. I need a little technical advice. I'm running a HK AVR 130 (55 watts/channel @ 8 ohms in stereo, 45 watt/channel in 5.1. What are the implications for this receiver when running 2 M2's at 4 ohms. Is it feasible? A bigger receiver is in my future plans, but not immediately. Thanks.

M22's, VP150, QS4's, HK 630, HSU VTF3-MKII
