This should be a useful forum to sell the parts.
I, for example, am looking for a metal speaker grill for the KP-115... so, depending on price, I may be interested in a part of the damaged KP-115.
You should be able to sell the good speakers as a set to a performer or DJ or such. As such, you may want a local buyer, and while I have no experience with ???list and similar internet connection types, they are probably one of the best for local sales... as well as bulletin boards at local colleges and music venues.
