I disagree with the others. These are $4K/pair speakers. That's considered peasant fodder to many on this forum but that doesn't mean what you have is curbside junk.
If you have an interest in hi-fi, resurrecting these speakers could be a great bargain. All you need do is contact Paradigm and ask if you can buy a pair of matched (important) tweeters and crossovers, maybe some wiring too. Take a multi-meter to the current drivers you have. If the measured resistance mostly matches their individual impedance rating (within 15% or so), and you don't hear any rubbing when gently pressing on the cones, they're likely good.
I wouldn't be surprised if all the parts you need can be had for <$500 (most of the production cost of like speakers comes from the cabinets). If you think it better to just sell the parts you have now, join Audio Karma, start a thread on them, make a few posts, then list them for sale in their classifieds. That forum has a much larger population of DIYers.
