A little recap: noticed a "buzz" in left sl2000 tweeter a couple of days ago. Assumed it was a bad tweeter. Ordered RD0-194s from Polk; they came in today. Threw them in the speakers, buzz is still there. This leads me to think it's either the internal wiring or the crossover. How do you suggest I locate the problem and fix it?
The buzz is most noticeable when playing piano music (ex: George Winston).
