I had the same problem years ago. Turned out to be something in the amp. The mfg had to replace some parts. I agree with Tmsorosk, see if you can try a different amp to help isolate the problem.
Good luck, John

Help My Nautilus B&W 804's 'pop' at loud volumes.
When listening to loud volumes for long periods of time (around 2 hrs), my left speaker has begun to make a loud 'popping' sound during a stressful point on the speakers (example: Explosions near the end of 'The Dark Knight' Batman movie, or a tight bass hit during play of the new music Blu-ray version of Rush's 'Moving Pictures'. There's no evidence of a tear in the speakers dust caps, cone or their surrounds.
It doesn't seem to happen earlier during my listening experience. This leads me to believe it may be Amp or 'heat related'. But I'm still curious why it only happens to the left side speaker.
The speakers are driven by an Anthem AVM-20 pre/pro and MCA-50 amp. I'm using RSC Prime BiWire speaker cables by Tara Labs.
Thoughts?
