I spent two hours yesterday at Best Buys auditioning JBL speakers and picking the brains of various salespeople with various degrees of knowledge. The "department manager" advised that he would not buy the JBL sub because of problems with the sub. He indicated they are seeing 50-60% failure rate on JBL's. He also said that the problem may be with older units mfd. before January 1, 2002, but he was surprised that JBL did not do a recall on the subs. He advised either the Sony WM-40 or the Cerwin Vega 12" (don't remember the number), and further suggested the Sony would probably not hold up for too long under hard use because of the paper used for the woofer. Any experience or opinions??
