have you read and followed the detailed instructions for audyssey on the avs forum? I haven't. Maybe someday, but I'm waiting to get all of my speakers installed first. (When I find the time and am not too tired).

Atta boy, Ken C., Screw Audyssey!
No way the VP100 EVER produces 40 Hz, no matter where you put it. Like I've always said, Audyssey is error-prone.

Even if it's sitting flat on the entertainment center behind my TV? I need to re-run the calibration, I know; I was just wondering if anyone else had the experience of the sub being way too low. I remember from way back that it was advised to calibrate the sub 10dB higher than anything else.

i think there's a very good way to check the sub's level.
run the LOTR's first movie and go to around 19 mins, when the ring drops on the floor. run the scene over and over and increase level in the avr until you see/hear that the sound is right for what you see on the screen.
that's the easy way i could judge with certainty the level i should use on the sub: 3 db more than what Audyssey told my avr.

i can think of only one reason some say to up the sub's level by 10 dB: that must be for bass-heads.

I was listening to "Desert Rose" by Sting, which usually has some pretty good bass.

Hi Ken,
All joking aside, the VP100 measured in Axiom's anechoic chamber at 40 Hz is -20 dB "down" from its upper bass and midrange output levels. Even allowing for bass reinforcement from adjacent surfaces like your entertainment center, that would add 6 dB or perhaps a little more to its output at 40 Hz, leaving it -14 dB down. You might see the cones of the woofers move at 40 Hz, but I doubt you'd hear anything. More likely you'd hear the 2nd harmonic at 80 Hz and the VP100 would have significant audible output there.
As to subwoofer levels, it's also dictated by not just personal taste on the part of the mixing of the source material, but a matter of what is considered "realistic". If you were a devotee of disco-era music, the bass is usually mixed at a very loud level. I used to like some disco, on disc and in clubs, where the bass was incredibly loud. The latter was fundamental to the driving dance rhythms. In that sense, hugely powerful bass from disco music would be realistic.
In good concert halls, the reverberations of a big bass drum are certainly present, but they aren't overwhelming -- at Carnegie Hall and the Metropolitan Opera House, it's thrilling to hear them but they are not ultra-loud. When I play back well-recorded classical and opera works with bass drum, I tend to increase the subwoofer level, knowing full well that I'm playing it somewhat larger than life. I enjoy the surprise of a big drum hit in my living room. Am I a bass-head? Sometimes.

On the avsforum site, concerning Audyssey, I see about 99,999,999 messages on Audyssey that, so far, had nothing to do about how to properly perform the job. I'm definitely not going to weed through all that.
