Keep your JBL compression drivers running with the SA-DR6 replacement diaphragm. This 16-ohm titanium dome diaphragm restores performance to JBL 2420, 2425, 2426, and 2427 compression drivers when the original fails or degrades.

The SA-DR6 delivers the same frequency response and output as your original JBL diaphragm at a fraction of the replacement cost. The titanium dome construction provides durability and consistent high-frequency reproduction that compression drivers depend on for vocal clarity and instrument definition.

This diaphragm features a 2.95-inch diameter with a 1.75-inch voice coil, matching original JBL specifications exactly. The 16-ohm impedance ensures proper power handling and crossover compatibility. At just 0.06 pounds, installation is straightforward for any technician familiar with compression driver service.

Sound engineers use these diaphragms to maintain PA systems for touring bands, house of worship installations, and permanent venue sound systems. Whether you're servicing a club's monitor wedges or a theater's main arrays, having backup diaphragms prevents costly downtime when drivers fail during critical events.

The SA-DR6 works as a direct replacement — no rewiring or crossover modifications needed. Simply remove the failed diaphragm and install this unit using standard compression driver service procedures.

Backed by Seismic Audio's one-year warranty and fast shipping, the SA-DR6 keeps your JBL compression drivers operational without the premium price of factory parts.

Frequently Asked Questions

How do I know if my JBL compression driver needs a diaphragm replacement?

Common signs include distorted high frequencies, reduced output, crackling sounds, or complete failure of the high-frequency section. If your compression driver suddenly loses volume or produces harsh, distorted sound during normal operation, the diaphragm likely needs replacement. Testing with a known good signal source can confirm whether the issue is the driver or another component in your signal chain.

Will this diaphragm work in my JBL speaker cabinets?

The SA-DR6 is compatible with JBL compression drivers models 2420, 2425, 2426, and 2427. Check your driver model number, which is typically printed on the magnet assembly or driver housing. If you have JBL speakers but aren't sure which compression driver is installed, consult your speaker's manual or contact the manufacturer to verify compatibility before ordering.

Can I install this diaphragm myself or do I need professional service?

Diaphragm replacement requires disassembling the compression driver, which involves removing screws and carefully handling delicate components. While technically possible for experienced users, most compression driver manufacturers recommend professional service to avoid damaging the voice coil or magnet assembly. Improper installation can result in reduced performance or complete driver failure.

How does this compare to buying a new JBL compression driver?

The SA-DR6 costs significantly less than a new JBL compression driver while restoring full performance to your existing unit. However, if your compression driver has additional damage beyond the diaphragm — such as a damaged voice coil, cracked magnet assembly, or corroded connections — you'll need a complete driver replacement. This diaphragm is most cost-effective when the rest of your compression driver is in good condition.

What tools do I need to replace the diaphragm in my JBL compression driver?

Diaphragm replacement typically requires screwdrivers (Phillips and flathead), needle-nose pliers, and possibly a small wrench set depending on your specific JBL compression driver model. You'll also need a clean workspace and careful handling to avoid damaging the voice coil leads. Some technicians recommend having electrical contact cleaner and a soft brush available to clean connection points during reassembly.
