I turned on my equipment today and realized that the tweeter in one of my RTi A7's isnt working. What should i do to test what is wrong? I tried hooking it up to 4 different amps and still no go. Everything else seems to work just fine though.

    Do you own A multimeter? If you do remove the tweeter and check to see if the voice coil is open.

    It sounds like its time to buy a replacement tweeter. You can contact polk to find out how much they cost and tell them you are a member here on this forum I believe it gets you some degree of discount when ordering replacement parts. Or you can try that auction site and see if any used ones are available.

    X.x called earlier, hopefully the other one doesn't go either.

    You more than likely sent a clipped signal from the amp that drives your fronts. Clipping will occur when the volume level spikes or is flat out too high and the amp doesn't have the power reserve to handle it. Looking at the specs for your amp I see it weighs 18 lbs., which means it doesn't have much of a power supply. Hell, I've got CD players that weigh more than that. The solution is to either keep the volume level lower or buy a beefer amp(s).
