I have noticed some of you discussing a small electronic protection unit used in the Polk SDA 1.2's, and I believe I may be having an issue with these. I have the regular 1.2's and not the TL. I did uprade the tweeters, recently, with the dome ones from Nakamichi, I, of course, did all 8. Now that I have the newer tweeters, do I still need this level of protection? The reason I ask, when I am giving these speakers some heavy wattage, the tweeters will go dead. Almost every time it is both channels doing it, and only once has only one speaker had the tweeters go dead. I turn volume down, and they kick back on. There is zero distortion or amp clipping going on when the tweeter protector diaphrams(?) kick in. Should I get new ones, or are they working properly by protecting these expensive tweeters.

    You need some new polyswitches, you can get them from Polk CS, if you send then an email they will probably send em' your way for free..

    Sorry...I didn't mean to put Nakamichi in there...however, I am as big a fan of Nakamichi as I am of Polk Audio. I will get the new poly-switcheroo's and put them in. They are getting worse every day...tonight my treble is kicking off far before they are turned up loud.
