I got my F12 today from Beach Audio, 3 days after ordering it..nice. I just set it up and am impressed with it so far. My wife doesn't like it though..

. I really did not get a chance to put it thru the ringer because it is late where I live, and the little ones are asleep.
I have it hooked up to a Denon 789, and I noticed Audyssey set the distance of the sub at 19 feet..where it was actually only 10 feet away from the calibration mic. Does anyone know why this might be? Maybe I did not set it up right? I had the phase set to zero, since it is right next to my right front speaker, and the subs crossover frequency control disabled.
I checked the Audyssey thread, and this is what it states...
"Many powered subwoofers do not provide the capability to defeat the built-in low-pass filter. These filters, by their nature, introduce additional delay in the signal and MultEQ finds that and reports it. The optimum solution is to turn the filters off (often called "LFE mode" in subwoofers). If that is not possible, set the low pass frequency to the highest possible setting and leave the distance reported as is. MultEQ will compensate for the added delay and time align the subwoofer to the satellite channels so that the optimum blend is achieved."
From how I read it..it seems to say to leave the crossover frequency knob on it's highest setting?..but the sub has a switch on it to disable the crossover frequency knob, and I selected that option when I set it up. I just want to make sure I did everything right as far as setup is concerned, and my distance with what Audyssey reports might be common with subs. Any info would be much appreciated.
