Anyone heard of JVC Victor SX-500 speakers?


A friend of mine aquired these and seems to like them a fair bit. Unfortunately one of the drivers is blown so it needs to be repaired. Any suggestions?
Any comments or information on these would also be appreciated.

Typically the Victor line is associated with the JVC better equipment, at least in the case of their Headphones. I have a pair of Victor HD 1000 headphones available only in Japan that compete with some of the best headphones available at any price.
