Need some advice for a 115H-1

[DMMD]

First off: This is my first post. Great wealth of information here. TO be honest, I only discovered this site last week. Anway- thanks. I'll do my best to add to the quality already present.

Anyway- I've got a couple of pairs of 4406's in service and I recently got a hold of another. One of the 115H-1's has some resonance in it- sounds as if the voice coil was lifted/overdriven. Not sure if it is fixable, and since no kits are available, I may never know.

JBL Pro's techs offered up their "closest" replacement- which I was told was the 6" that's in the 4206... it's a 506G-2S stamped alum something or other...:bs: That's impossible right? This driver doesn't look anything like the 115H-1... and it's a different size, has a different range... but maybe I'm missing something.

Advice? HELP? Anyone with a 115H-1? Anyone that want's to offer up some help in diagnosing the failing 115H-1 would be much appreciated.:banghead:

Start calling recone centers.

Several of us bought up a few of the 115H-1 kits that appeared on eBay awhile back. Another might show up at some point.

In addition to the 4406, be aware that the 115H-1 was also used in the 18Ti, L20T, L20t3, XPL200, and XPL200A.

I may be able to "non-destructively" disassemble the driver, and repair the cone assembly. Been able to do this for a number of other drivers with "irreplaceable" cones... recover the original cone, but replace the voice coil and spider.

PM me...

Regards,
Gordon.

Follow-up: Learned from JBL that the 506G-2S is based on the 115H-1, but with a shield on the magnet and an aquaplas cone instead of the polyfil.

Catch: The circum of the frame mount holes is 5mm too small though, so the 506G-2S simply doesn't fit. Otherwise, it specs out as nearly identical according to JBL's computers. There should now be a note that it doesn't really fit- thanks to a little trial and error.

I guess if you wanted to DIY a small monitor or are looking for a current production mid , the 506G-2S might be a slightly less expensive option than the Performance 6.5 driver...
