I am having a few problems with the centre channel on my new system. The overall sound is superb but the centre just seems a little lightweight, and quiet. I turn up the volume loud to say -16 and i can hear it fine but then my room shudders when there is an explosion.I have tried increasing the db and increasing the distance and neither really seem to adjust the volume, just the tone really, it goes far too bright!! Cinema EX adjusts it slighlty but as an overall i feel the centre voice is too low compared to the rest of the track which is loud and superb. Any ideas?? Moving the sub nearer wont work cos its active , will it?
