Cerwin Vega AT-15 screeching problem

garnerac · 28th January 2005, 03:45 AM

I need to know where I can get a new crossover for one of these. I get a screech out of my tweeter when I just touch the 2 knobs that adjust the range. I also notice the tweeter only works on occasion and sometimes makes a wierd noise while listening to my HT system.
Ive checked the connections on the speakers and I dont see any visual problem on the back of the crossover.
Im not even sure "crossover" is the correct term. There are 2 knobs that control the mid & high range with a circuit board. The problem seems to be there.
Someone please help me!
Watching HDTV in 5.1 is really diminished when I hear that "screech" !!!!
Thanks, DG

Check with Cerwin Vega. They may still carry parts.

If your speakers are as old as mine (AT-12 from '89) were, they probably are nearing the foam rot stage and the woofers will need new surrounds....

It's a real crossover,BTW, with cheap small-cored inductors and decent mylar caps.....
