	woofer: foam surround crumbled

unfortunately, tweeters rarely show visible damage.

check the connections in back. are they secure? tighten the speaker wire or connectors if necessary.

if you've checked the above and you can't find the problem, some component may be loose inside the cabinet, or the problem is more serious. Time for the repair shop.

Many times, repair is as easy as reconnecting plugs and clips inside the cabinet because they've become loose from vibration. other times, the original manufacturer cut costs due to price competition and used inferior or underrated components that have blown during use.
