blown tweeter?

[mopar dave]

i think i may have a blown tweeter on one of the cornwalls. it sounds fine at low to mid levels, but when i twist the volume up above that (100db) it distorts. i'v blown tweeters before and they quit working completely, this ones alittle different. i also tried swaping the amp tubes from one side to the other, rebiasing and had the same results. what do ya think, blown tweeter or another problem? dave

Try changing your Left and Right cables, see if it follows. If it were another amp problem, switching output tubes would have no effect.

Get Back. A tweeter can "go" but still work and sound fairly good until a certain volume is reached.

Make sure your tweeter cap is not shorted as a full range signal will be sent to your tweeter, which can definitely cause a tweeter to distort at high levels. You could switch the tweeters from one Cornwall to another to see if it is the tweeter or the crossover.

Andy, that does sound like a blown diapragm, BUT:

Double check the wiring first, because a bad or oxidized connection (xover-tweeter wire) also acts and sounds exactly the same way.

I had the same problem with my Forte's and found the voice coils in the horns blown. At the time when Klipsch owners were like Harley Owners, I was given a set of voice coils for free. Recently my wife fried the coils again and when I went to the local audio shop they were ready to charge me $30 each coil. If anyone knows a better source for where we Klipsch-aholics can get these coils cheaper I would appreciate a message.

thanks guys, i think klipchguy may have been right on this one. pulled the back off speaker and noticed that the caps had come loose from the crossover board, the glue did'nt hold. the soilder joints may have been touching on hard bass notes. changed the tweeter while back was off. problem went away. jammin again. dave
