JBL LE14H-1
Surviving documentation on the JBL LE14H-1 is thin. Here is what the record shows. It was a 14-inch (38 cm) woofer with an 8-ohm impedance, built around a polypropylene cone with a rubber surround and a butyl rubber dust cap. The voice coil was aluminum on a high-temperature former, rated to handle up to 200 watts RMS. That's the whole verified spec sheet. No production years, no frequency response figures, no sensitivity data and no original price have turned up in the sources available to the Archive.
What we do know with confidence is where this driver was used: the JBL 240ti and 250ti loudspeakers. The LE14H-1 was the dedicated low-frequency driver in those systems, and it is still the correct replacement woofer for them.
The aftermarket is well stocked. Refoam kits, recone kits and complete repair services for the LE14H-1 are all readily available. One German supplier offers surround kits specifically for this driver, and a Russian recone kit from Upland Loudspeaker was listed at 64,690 rubles. A repair shop in Eastern Europe described having to fabricate custom diaphragms to preserve the original electro-mechanical parameters. One forum commenter noted that JBL's own complete recone kit, while still obtainable, is pricey, and that the original surround doesn't hold up as well as aftermarket alternatives.
On the used market, the LE14H-1 shows up in two conditions. Working examples, often pulled from 240ti or 250ti cabinets, command prices in the $250-$1,075 range. Cosmetically challenged units needing repair have been listed as low as $250, sold strictly "as is" with no returns. One Danish owner of a pair of 240tis was bothered enough by the cream-colored cones to paint the drivers black, and reported being "super tilfreds" - very satisfied - with the result.
If you own an LE14H-1 or have come across period literature mentioning it, the Archive would welcome the details. For now, this page is a placeholder for a driver that is better known through the speakers it powered than through its own documentation.
