Brand New Genuine JBL D8R2421 Diaphragm for the JBL 2421A, 2421H Driver 8 ohms.
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
➡ Special-Order: Lead time is about one week.
