Is my amp clipping?


I'm having a problem with my tweeter at moderetly loud levels (95db at listening position). Whenever there is a somewhat dynamic song -- with decent base -- the tweeter crackles and pops.

Speakers are 850 Rockets (91.5 Efficiency) from AV123 driven by Belles 350A Reference. Could the amp actually be clipping at such moderate volume levels?

If not the amp, could it be my Oppo CD player?

Damage is done, your amp may or may not have clipped at one time but I bet your teeter is in need of replacement.

Hmm...the tweeters still sound find at low volume. Has anyone heard of a CD player doing this?

No way the amp is clipping. Could be the tweeter or the amp/preamp. I assume its in one tweeter only? If so switch the speaker wires to the speakers and see if thre crackle follows, if so its the tweeter probably (or tweeter crossover).

Could be the volume pot, or any number of shorts, parts, you didn't mention if you had a preamp. Sometimes the volume pot has crud in it at higher volume settings of the rotation that causes just such a problem, just (unplug for a while) and blast it with some contact cleaner.
