Not sure what to say? Did you happen to come into these for free? Like a Storage Wars type scenario? Lol. That’s a different story. Not sure how they’d do in terms of resale or collectibility. But something tells me if you have a very large room, a large multi channel amp, good cables and a large center channel you could have a movie theater like experience...after that speaker is fixed... I guess? Then again, it is 26 year old equipment and for not a large amount of money you could buy a new 5.1 set up that would also kick butt and completely do the job and come warranties etc.

Hello - by 'voice coil separation' do you mean that the rubber or foam surround of the cone has disintegrated? If so, it's a fairly simple DIY repair to install new foam surrounds or you can have them repaired by any number of repair shops. Failing that, simply replacing the drivers should be easy - just unscrew them, disconnect the terminals at the back and fit the new units.
