The sub and four satellites work great. The center channel contains two small speakers, one of which started buzzing so I disconnected it. My guess is a single replacement speaker to put back in the center channel casing would be pretty inexpensive. I haven't bothered since I'm not using the speakers.
Full disclosure: these speakers are probably 20 years old, and I paid $1000 at the time of purchase. That said, they sound excellent and I wouldn't be looking for replacements if I was setting up a home theater system. For the price I'm selling them, it's worth it for the subwoofer alone.
If you're reading this ad on Craigslist, it is still available.
