Talked to JBL and the tech said to take them back to speaker shop because it sounded scwoowy to him. So another trip is in order.

An addendum: I've got some Creative computer speakers that cost, maybe $15, and some Bose computer speakers from Best Buy that cost around $100. Neither has ever had a problem (years). Now I've got some $700 speakers that don't last 7 months.
