Axiom Home Page Forums General Discussion Home Theater Do these trim levels sound correct?

It could be correct if the mains are farther away than the center from the measurement points. There could also be boundary effects that are boosting the center channel, as the others have mentioned, if it is inside an entertainment center or near some other object/wall etc. If you have an SPL meter I would double check with it and if you don't now is the time to go get one and double check the settings yourself.
