I've had the switch on digital the whole time. Based on the manual, when its switched to digital the difference is that the crossover frequency is handled by the receiver so the dial on the sub has no impact, while when its in Pro Logic the crossover frequency is handled by the sub's dial.
I've tried running Audyssey a few times and I can't even get Audyssey to detect the sub unless I crank the gain on the sub at least halfway.
Also, I tried moving the sub last night and using my old Sony receiver. Same issues. I'm not very knowledgeable when it comes to diagnosing speaker problems, but from a layman's knowledge level I'd think there has to be something wrong with the sub's amp. It seems like its only operating at about 10% or so of the power it should be.
I watch a very LFE heavy scene last night from Casino Royale with the grill off and the woofer was barely moving during the entire scene with the gains on the sub and receiver cranked up all the way. I also tried turning the sub off to do a comparison of the bass using only the main speakers and they gave off considerably more bass than the sub when its on.
I placed a call to BIC last night and left a voicemail so I'm just waiting to hear back from them. The lady of the house contacted our dealer, SoundDistributor's, and they were not at all helpful. They basically insisted it was the receiver set-up, without ever really hearing the things we had tried to rectify the problem, and then just said to call the manufacturer if you think its the sub. I wouldn't normally have a problem with this, but when your repairs and returns policy says they'll handle the problem and they don't want any involvement that really ticks me off.
