Likewise - one of my M3s is in a bit of a corner where the closet "bumps out" and gets reinforcement from the walls there (-3dB on the levels to even it to the left main)... same with the left QS4 - it's got a wall/corner to reflect off of so it's also 4dB hotter than the the one on the right which is 10 feet from it's corner.

That's why those level controls are there... gotta use them... your ears aren't sensitive enough to do it by "ear".. though some people do "tweak" their levels out of even (bumping up the centre and almost everyone runs their sub hot).

Remember that if your center is on a shelf it needs to be at the very edge of the shelf and even protruding a bit for optimal sound. Somebody else had posted earlier that they weren't sure about their VP150 as they always needed to turn it way up to hear dialog, but then discovered that their placement was too far back on a shelf and once pulled forward to the edge of the shelf they were able to hear it just right without making it "hot".

I recently calibrated my system using the Avia Calibration DVD and was very surprised just how hot I was running the sub. I still tweak it up and down a bit, depending on the DVD or CD being played but nothing as high as I was running it before.

The disc along with a RS digital SPL meter really has the system sounding much better than what the 'auto calibrate' feature on the HK 635 did.
