Power protection circuit?

[telext]

I own a pair of BIC America floor speakers and play them pretty loud. Last night the woofer on the left one stopped putting out. I know its the power protection circuit but i do not know how to reset it. I would appreciate some help. Thank you....

Look for a little protruding red button that can be pushed back in, or a cooked line fuse. If you have to play them loudly for them to sound good, maybe it is time for you to get better speakers?
