Also, what is your crossover set to on your sub (the knob physically on the sub)? It needs to be turned all the way up to it's max (100-150hz usually) to allow the crossover from your AVR to function without any "interference".
I'm betting you heard port noise (chuffing) from the sub. Best way around this is to turn down the gain on your sub (the physical knob again on the sub) until your audyssey shows you at 0.0 and your distance is set correctly (it took me 6 times to get it dialed in, so be ready for some work). This should keep your sub essentially from being turned up too loud to perform properly at that level. If it still does it, you may just have an underpowered, underperforming, and/or too small of a sub to handle what you are sending it.
95% that it isn't the 707, it's probably the sub, or a setting that isn't tuned correctly.
For proper sub performance, you set your sub to or above the crossover from your main speakers. For example, my speakers are all 80hz crossovers, so my knob on my sub is turned to 120hz, but the crossover in the AVR is just slightly above that of my speakers, so it's at 90hz (I have reasons for doing this). If your crossover on your speakers is 120hz, you leave your knob up as far as it can go, and set the avr to 120hz. You don't need to re-run audyssey if you change the crossover point, as it would just reset it on you anyway. You can change any of your speaker crossovers and distances at any time and it will maintain your multi-eq settings.

This is great advice and one of the simplest explanations I've read on this setting
My issue with Multi-eq is the sub level. My last calibration set my sub to -7db, which was within 3db of all other speakers (it always configures mine in the negative). However, to even achieve -7 my sub knob on the front was set between 1 and 2 (on a scale of 0-10). The crossover knob on the back of the sub was set to max (120Hz I believe).
I guess the issue is my 707 views the sub as over powerful. For the first few calibrations it always set it at -15db. The interesting thing is, with my old Onkyo TX SR573, my sub volume was controlled completed by the sub dial, at at volume 4 it sounded perfect.
All that to say its a bi*ch for me to calibrate/balance my sub so far!!
