jbl LE100S w/ M5040 horn?

[rjtimmerman]

I have a Compression driver version LE100S 8 ohm-with a factory M5040 elbow type horn. What was the original application of this driver? I can not find any thing about it. It looks just like a LE175.

I think the 5040 was used in the Metregon and the LE100S was simply an OEM driver with a phenolic diaphragm. I'm not sure if it was the same as the 2460 or the 2470. If you know how much just the driver weighs then that will tell you. I have a weight of 12 pounds for the LE100S (but that could be wrong) and LE85/2420/2470, and weight of 8 pounds for the LE175/2410/2460. Or you could go by diameter. The LE85/2420/2470 is 5.75" while the LE175/2410/2460 is 4.5". I have no diameter for the LE100S.

Hi there,

The LE100S was a 2460 in disguise . Old "Goes INTO" sheets show the D162460 diaphragm as "going into the : LE100S, LE175HP, 2460 and the 5P350 ( Dukane part # ). The D16R2470 went into the 2461 ( improved diaphragm ), 2470, and the 5P355 ( Dukane ).

Just picked up a pair with mismatched diaphragms.
Does anyone have any links on information and how to replace diaphragms for this LE100s driver

Hmmm, I don't have any links ( to post ) that directly address replacing diaphragms in older JBL drivers ( maybe others do ) but,

all older small format ( alnico magnet type ) compression drivers had locating pins that centered the replacement diaphragm .

Sorry Vinny, I don't do private communications with forum members here or at other forums ( that's why my PM access is turned off ).

You had asked someone earlier to pm you while ago. So if you don't take pm or text can you help me out with two inquiries.
Whats the perfect model horn I could replace the current bent one 5040. How about the Short potato masher 2170-2290? The current 5040 I was told is limited and restrictive.

The diaphragms you mentioned in previous comments is confusing. Which 16 ohm diaphragm would be the most musical one to get and what's the model number and where on the net can I buy a pair. Thanks
