Brand New Genuine Authentic JBL D8R2421 Diaphragm used in 2460H Driver 8 ohm. LE85 and LE100S also use this diaphragm.
Please note: JBL changed the design of this diaphragm decades ago. It now has a “diamond edge” instead of the “spiral jiffy pop” edge that it used to. If you are looking for the old “jiffy pop” edge, you can use our aftermarket diaphragm: 2420-27 AM
