Thanks for the feedback..I ended up picking up the m&k AND running it with the Martin Logan for a 2 sub system..the m&k seems to go lower but the Martin Logan adds a nice tight bass punch..sounds great with the M&K satellites! Now I'm considering a high power amp for the Satellites..they sound pretty damn good with my HK 120 watt amp receiver, but I'm wondering what would happen if I got a 250 watt per channel dedicated amp? Any thoughts? How's your system building going?
