Not having any luck with the Bose site. Unable to find anything remotely helpful on their site, especially the customer support pages. :(
I like the sound from this speaker system but the physical configuration is sub par.
My situation is not unique. Many people have had their cubes separate after a cat pushed them off a self onto the floor. The fix was actually easier than this guy said.
Speakers are now fixed but I discovered that one of the tweeters was damaged (from a fall?) so now we have an excuse to get a new/better center channel for the home theater.
