Title: JBL 066 tweeter for L166
Post by: Slim-Shaddy on January 28, 2010, 12:22:19 PM
I picked up a pair of l116s from Tom yesterday and one of the tweets are bad. I thought I had it working, but as it turns out I was just losing my mind. The speakers sound great outside of the bad tweeter. I know it's a shot in the dark, but do any of you have a 066 replacement?
Thanks

Ok.... Not going crazy it did it again.........
What does it mean when a tweeter plays barely audible, but when you throw power at it it kind of "pops" back up to the loudness it should be?
Also, it's not the crossover or L-pad. This happens while running directly from the amp.

New problem... One of the 122a woofers' voicecoils is getting a little too into the music. He's bumpin' and grindin. Anyway... it's not terrible. I can push and pull the woofer with no rubbing, but certain bass notes cause it to grind. Is this something that can be fixed easily or will I need a whole new re-cone? If it's a pain in the ass I'll just buy a replacement.

Those woofers were re-foamed by JBL. They may not have centered the VC proper. I can re-foam it again and do it proper.  JBL woofers are a bit tricky sometimes.

Ok...I really hope that's what's going on with them. Those woofers aren't cheap, and recone jobs are even more expensive

That's exactly what it is. I pushed at the surround all along the circumference and it rubbed at the top and left, and had free play at the bottom.

Try flipping it in the cabinet, gravity may be enough to stop the rub until Tom can re-foam it.

WRT the tweeter, you say you've got it connected directly to an amp !!??  Full range !!??

I just had it connected for a second at low volume until it kicked on. Bear in mind I thought it was bad... As for the woofer, I already have it out and devoid of foam.
