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

Would the fact that the m60s are 8ohm and my vp150/Qs8s are 6ohms make a difference?

I believe it would. The 6 ohm speaker at any given level on the volume will play louder. That's what I was referring to in my first post. Not only that but they both have a higher sensitivity rating which requires less power at any given volume.

As others have stated. Get an SPL meter. Then there will be no question that they're set correctly.
I picked up the cheap $50.00 unit and a tripod from Radio Shack and it has proven to me that the YPAO on my Yamaha doesn't always get it right.

Forget the numbers for a second.... does it sound right?

Is your 150 below, above, or at the same height as the m60 tweeters? If it is below/above, is it angled towards your ears. When running the Audyssey locations, how did you place the microphone, on a stand, on top of your seats? If there is any reflective material between the mic and the speaker it can skew the results. For ex, in my case I have 2 rows of theater seating, I have to recline my font row recliners flat when taking the rear seat measurements, otherwise, the front seats will affect the results. It is also possible your room is to "dead" with treatments. Bass traps and first reflection panels are a good thing, however, over treating is not a good thing.

Sot, you ask "Does that sound right", but Micah justifiably asks you how does it sound. As has been mentioned, there are many factors involving different speaker specs and/or placement that could result in that trim difference being justified. Have you been having unusual difficulty hearing dialog or other center channel sound? If you simply run the internal receiver calibration sounds, does it sound to your ears that there's a sharp drop(you report about a 9dB lower trim on the center)as the sounds travel from left main to center and then a big increase up to the right main? You don't have to necessarily use an SPL to check for this difference. I have an SPL and my level measurements with it differ slightly from the Audyssey results, but I'd be a bit naive to assume that my human error is less than any error of the automated setup.
