Asking for assistance with a Bose product is asking for trouble.

The Wave system (which I've heard) is a profoundly mediocre product sold at
a premium price. This failure would be a good opportunity to listen around
for something better. You should be able to find a $200 "executive" system
at Costco with substantially better sound. It won't be a "single-piece"
system, but a single-piece system that delivered really good sound would be
large and unwieldy.
