I guy at work was giving away a pair of RTR300D towers. They are 3 way speakers with 2 10" woofers, a dome mid and a dome tweeter each. The cabinets are in pretty good shape, but the foam that attaches the cone to the basket on the woofers is brittle and a lot of it has cracked or fallen off. I'm also suspicious about the condition of the mid and tweeter since the woofers are so bad off. It sounds like RTR is long out of business and there is not much info about these speakers on the web. What options do I have for restoring these guys? re-foaming? speaker replacement? I'm pretty new to speaker building, so any advice would be appreciated.

cheers
Ben
