I scored a pair of these from goodwil today. I had ignored them for two weeks untill today I went to move them to look at an old AA5 radio and felt how heavy they were. I picked them up out of curiosity and pulled the grilles and hello-a planar ribbon tweeter! Hmm, I guess for $20 I should get them I thought. They are 5" kevlar woofers with the Linaeum tweeters. RCA, but made for radio shack as indicated by the RS model number 40-5037. What to do with these? Yes they have stunning imaging, but the rest of them don't sound much better than your average boombox speakers. I did stuff the ports with straws and threw a wash cloth in each for damping. I have a few options here: 1) flip the speakers on ebay, they seem to fetch up to ~$100 a pair. 2) flip the tweeters alone, maybe they would go for more or less, but shipping would be cheaper. 3) add an external x-over and custom make some little cabinets and add them on top of my RS Nova 6's (which suffer from poor imaging due to the paper tweeters.) Thoughts?
