...and now I can listen to my music at a normal volume!
Ever since I have had my SDA 2A, if I played them too loud (which wasn't very loud), the left tweeter would cut out. I final got frustrated at a listening party tonight and just eliminated the polyswitch. Not only do the speakers sound great, but they dont cut out! I was putting some heafty power to them tonight and they are fine without the polyswitch (a 600wpc Carver amp). I really am suprised how much power SDAs can take. I was driving them with a 200wpc Audiometric amp, but the power of the Carver really makes them come alive.
One odd thing though. The polyswitch on the left speaker was blue, and on the right speaker it was yellow. My guess is that someone replaced one at one point but the other worked fine enough to leave it.
Moral of the story is: If you are having an issue with your polyswitches, just get rid of them.
