Technical Specifications

Frequently Asked Questions

Will this diaphragm work in my JBL EON15P speaker?

Yes, the SA-DR5 is compatible with JBL EON15P speakers that use the 2418 series drivers. It also works with JBL 2418, 2418H, 2418H-1, and EON G2 10-918 models. Check your driver model number to confirm compatibility before ordering.

How do I know if my diaphragm needs replacement?

Common signs include distorted high frequencies, crackling sounds, reduced output, or complete loss of high-end response from your speaker. If the driver produces no sound or sounds muffled compared to other speakers in your system, the diaphragm likely needs replacement.

What tools do I need to install this replacement diaphragm?

Installation requires basic hand tools to access the driver compartment and remove the horn assembly. The SA-DR5 features quick-disconnect spade connectors, so no soldering is required. Most technicians can complete the replacement in 15-20 minutes per driver.

Can I use this diaphragm in other brand speakers besides JBL?

The SA-DR5 is specifically engineered for JBL 2418 series drivers and their exact mounting and electrical specifications. Using it in other brand drivers may result in poor fit, impedance mismatch, or performance issues. Stick to JBL-compatible applications for best results.

Should I replace both diaphragms if only one failed in a stereo pair?

While you can replace just the failed diaphragm, replacing both ensures matched performance and prevents the remaining original from failing during your next event. Many sound technicians replace both diaphragms simultaneously to maintain consistent sound quality across their PA system.
