The SA-DR2 titanium diaphragm gives sound engineers, venue technicians, and touring professionals a direct replacement for blown JBL 2412 drivers without the downtime of shipping speakers for factory repair. When your horn driver fails mid-show or between gigs, this 8-ohm diaphragm gets your PA system back online fast.

This titanium diaphragm delivers the same performance specifications as the original JBL component, maintaining the frequency response and power handling your system was designed for. The precision-engineered construction ensures seamless integration with existing crossover networks and amplifier settings.

Built with an 85mm gasket diameter and 1-inch voice coil, the SA-DR2 fits dozens of popular JBL models including the JRX series (JRX100, JRX112, JRX115), EON series (EON1500, Power10), and TR series (TR-125, TR-225). The 8-ohm impedance matches factory specifications, so your amplifier load calculations remain unchanged. Quick-disconnect spade connectors simplify installation without soldering.

Churches running permanent installations, mobile DJs working multiple venues per week, and bands on tour rely on the SA-DR2 to minimize equipment downtime. Venue sound systems serving 200-500 people often run multiple JBL boxes where a single driver failure can compromise coverage for an entire section.

Installation requires basic hand tools and takes under 10 minutes per driver. The diaphragm connects via standard spade terminals to your existing crossover wiring.

Seismic Audio backs the SA-DR2 with a one-year warranty and ships replacement parts fast, keeping your pro audio investment working when it matters most.

Technical Specifications

Frequently Asked Questions

How do I know if this diaphragm will fit my JBL speaker?

Check your speaker model number against the compatibility list or remove the horn and measure the existing diaphragm gasket diameter. The SA-DR2 fits JBL drivers with 85mm gaskets and works with JRX, EON, TR, MPro, and Sound Factor series speakers. If your model isn't listed, measure the gasket diameter and voice coil size to confirm compatibility.

What tools do I need to install this replacement diaphragm?

You'll need a screwdriver to remove the horn from the cabinet and access the driver assembly. The diaphragm connects via spade terminals that push on by hand - no soldering required. Most installations take 5-10 minutes once you have the horn assembly accessible.

Will this diaphragm sound the same as my original JBL part?

Yes, the SA-DR2 uses the same titanium construction and specifications as the original JBL 2412 diaphragm. The 8-ohm impedance and frequency response characteristics match factory specs, so your crossover settings and amplifier load calculations remain unchanged.

Can I use this diaphragm for outdoor events and high-volume applications?

The titanium construction handles the same power levels as the original JBL component, making it suitable for outdoor festivals, large venue sound reinforcement, and high-SPL applications. Churches, concert venues, and mobile DJ rigs serving 200-500 people regularly use these replacement diaphragms in demanding environments.

How long will this replacement diaphragm last compared to the original?

The SA-DR2 uses the same materials and manufacturing tolerances as OEM JBL parts, providing equivalent lifespan under normal operating conditions. Proper amplifier matching and avoiding overdrive distortion will maximize diaphragm life, typically lasting several years in professional touring and installation applications.
