Hi John. Just finished that. Brent recommended the same thing. Still nothing. Took the woofer out and made sure all connections are good. Left it out and tried again. The woofer doesn't move at all. Anyway, Brent is checking with the engineers in the morning and will get back with me. Will let you know what the outcome is. At least it is still under warranty and Axiom is willing to make sure it is taken care of.
