I've noticed over the last couple of days that my VP 150 is making some 'squawking' noises when certain frequencies are present. I can duplicate it by backing up the movie, Tivo or whatever. It's kinda like a vibration or short humming sound. I've isolated the speaker to eliminate room vibrations and still get the noise. Does this sound like a blown speaker? I never push the system past moderate levels. The system is two years old this month.

Any thoughts? I guess I'll try calling Axiom later this morning too.

Thanks.
