Have you heard them? $600 is a bit much based on hearsay IMO.
Thanks guy's I appreciate all the feed back on these speakers. The cabinets on these are almost perfect, the glass tops are mint. The woofers have been refoamed at a pro. JBL auth. shop. All the drivers work perfectly. I am picking them up today. Thanks again for all your in put. Hinodit.
If not, you can redo them yourself. I find attaching surrounds from the rear easier to do than attaching them to the front of the cones.Check that they've had the foam applied to the rear of the cone as they were originally.

What are the major differences between the 077 and 075 (seem to be many around of the latter)? There also appear to be diaphragms available to repair them (both?). Are diaphragms interchangeable between these?Not with 077s in them.

After rebuilding a number of drivers I'm very hesitant to mixing and matching diaphragms, especially with what you have just mentioned.The 077 is the consumer version of the 2405, has a clear acrylic phase plug in a diffraction slot. The newer 2405H is a lot easier to come buy, and it and the regular 2405 have an aluminum phase plug that's much less prone to breaking when you change the diaphragm. Uses D16R2405 diaphragm.
The 075 is the consumer version of the 2402. It's a bullet shape instead of a slot. Uses D8R075 diaphragm.
As for diaphragms... Strictly speaking, there are different diaphragms for the 2 different drivers. Some guys use masking tape or broccoli bands (inside joke, he'll get it if he sees this) in an effort to shoehorn the wrong diaphragm into whatever tweeter they have. But it's really academic since virtually nobody but hardcore enthusiasts will pony up the $160/ea (last time I looked) for the actual JBL diaphragm. That leaves the $30 aftermarket replacements that by most accounts suck.
Here's an exchange with a guy who had some aftermarket diaphragms in a pair of 2404 tweeters and was puzzled about the performance.
It was replaced by the 122A in the L65A, then by the 129H-1 and every tech sheet suggests the 128H-1 as a replacement for all the above.What's the deal with the 126a woofer? Why is there little (nothing?) available on this driver? Was it short lived? No T/S stuff? Seems odd, unless it's old enough where T/S wasn't used or hadn't caught on yet?
