I was wondering if someone can suggest a clean way to match speakers from different manufacturers. I have a set of MB Quart QLS-series speakers (1030's in the front, a 330 in the CTR and and 530's as surrounds). I'm thinking about putting a plasma over the fireplace and this would mean the original fullsize 330 won't work for me. Instead, I need to get a wall-mounted center channel to go above the screen. MB Quart doesn't make a wall-mountable center channel so I'm pretty much forced to go with another manufacturer. Is there a clean way to do this besides test out several center channels? I've heard that if the sensitivity levels match that's helpful, but I haven't heard much else. Someone recommended an NHT L5 as a mountable center channel, but I have no idea whether it would work or not.
