So has anyone had a chance to use the cardboard "rocket" to use as a stand for the audyssey mic? I'm guessing it's better than nothing, but not as good as a true mic stand.

- Sony HW50es

I have never seen variances much more than .5dB, which IMO is "close enough". Especially for the low frequencies, where the RS SPL can be somewhat inaccurate, the calibrated mic shows that the level set by Audyssey is quite accurate.

Something wrong here. Take a look at the numbers please. Since the left surround is closer to MLP it should have the negative trim, but in your case it's the other way around. Care to cross-check again?

On a second note, can you go up close to the left surround and listen closely? The tweeter may be broken so Audyssey had to boost the trim. Just a blind guess to be ruled out.

There's nothing unusual in the trims being fairly different between speakers. The room will influence how loud the speakers sound - if some are in corners for example, and some are not, they will need to be trimmed down. As Jerry says, and as my own experience confirms, level setting is something Audyssey does almost to perfection.

Trust Audyssey to have this right. And when you say that one speaker sounds louder than the other, even though the difference is only 2dB, I start to worry you are overthinking it and maybe hearing things that are not really there - we all do this sometimes. Is your head when listening, for example, in the exact same spot as the mic was in when you measured the first position? If it is 6 inches out, then it will sound different maybe.

At the end of the day, it is your system and your ears. If you are not happy with the balance of the sound between the two speakers, then adjust the trim on one of them until you are. You won’t affect the actual calibration in any way.

It is extremely unlikely you have a blown tweeter BTW.

You may verify the case by swapping the two speakers and running Audyssey again to see whether the trims follow the speakers or not while keeping the physical distance of each, of course. Up to you.
Hi sorry I didnt pay attention with the distance. So it means the problem is my speakers? Pls let me know what is the problem is thanks

Maybe it is just your opinion that it is a "ridiculous excuse". And maybe not confusing people is a good idea.

Chris Kyriakakis: Audyssey MultEQ uses Finite Impulse Response (FIR) filters. Audyssey uses a proprietary method in calculating the filter coefficients, and so we do not disclose the resolution as it would lead to confusing comparisons with traditional methods.

With all the reverse-engineers on the Net trying to combat that little "x" I think it was a wise decision of Audyssey, indeed.

It is not an opinion. It is a fact. And if you feel yourself confused may be you shouldn't design/build your HT and pass it to someone else who is less confused about acoustics and related subjects...

What is so complicated about 1/1500 sec or 0.67 msec? Dirac, for example, have no problem with disclosing their Dirac Live FIR filter resolution - it is limited to 10 msec of time-domain correction and contrary to Audyssey they really do non min-phase correction with this filter... What is really confusing are the Audyssey claims about time domain correction while their FIR filters only approximate min-phase behavior (the same as any PEQ).

Talking about setting speaker trim level, I think AVRs are only good for those speakers with mid/low sensitivity (95dB or lower) in a typical sized room, which is common for HiFi speakers. In the HT scene, more and more people are using the pro audio speakers (example JTR/Danley/JBLpro) with sensitivity of ~100dB. Audyssey chirps will definitely set the trim to the max -12dB. In this case, we need an SPL to further adjust the trim...and 0dB will be louder than reference.

Interesting point. I have no idea if it's right or not. My own speakers have a sensitivity of about 90dB and my trims come out at about -7dB or so typically. It will depend on room size of course (my room is small) and on whether the room is heavily treated or not (mine is).

If anyone is here and using Klipsch or similar, perhaps they'd comment on their trim levels and if they are maxed out.

I have speakers rated with a sensitivity of ~90 as well, and the trims for my mains are close to zero. I also have a treated room.
