It's a long story, but in my room Audyssey wrongly applied 13db of boost at 10Hz compared to Audysset off and Monoliths don't like being overdriven below port frequency (18Hz IIRC). Some DVDs contain strong below 10Hz signals and that plus the boost did for my speaker.

I've just picked up a BFD this afternoon to help control the very low end from being overdriven.

Sorry for the OT, the XLS200 shouldn't be effected by this as it's sealed and will just naturally roll off these very low signals.
