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

I have a fully treated dedicated theater room. I am running m60s and VP150 for front a centers. Audyssey set my fronts at about +1.5 with my center at -6.5. Does that sound right?

Seems rather odd that it calculated your center channel so much lower than your mains, although I could be way off.

Are your mains quite a bit closer to the listening position than your center channel? My center channel is right under my display, against the wall; thus 1-2 feet behind my M80's.

The room and placement of the speakers will definitely have a impact. The results still seem questionable. I would defintely re-run auddyseey or even a better option is to go out and purchase a SPL meter to calibrate your system with. Verifying what auddyssey did with a SPL meter will tell you if the auto-calibration is having fun at your expense with your system.

With the sensitivity rating difference, the M60s at 93DB and the VP150 at 95DB, plus the difference in in the impedance 6 vs 8 I can see the reason for the difference.

Is the centre sitting inside the entertainment cabinet by any chance?

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.

I would def. verify with an SPL meter if you have one.

You could try the Ultimate ears app on the iphone if u dont have an SPL meter but do have an iphone.

I thought maybe because of the dual centers .....W150 & W100, I got readings like that with Audyssey. And not as dramatic, but still surprising readings when using a SPL meter.

But it sounds good! Is your room small? (Mine is)

Thanks for the input guys. The room is 23x17 with all walls acoustically treated up to ear height. The front wall is fully (dead) treated. The M60s are about 2' from the side and front wall. I have a false fabric wall made out of acoustically transparent fabric. The L,C,R are all 14' from the center of the room and the first Audyssey position. I have ran it several times and keep getting pretty much the same reading. I do not have a SPL but may get one.

Any idea if I manually tweak the trim up a couple of points, does that effect audyssey? Right my L and R are at +2 and my center came in at -7.5 My four QS8s are all in the -3.0 range. I tried turning up the center to -5.5 and when doing level comparisons on my Onkyo 876, that to my ears sounds close.
