When your Seismic Audio titanium compression driver stops performing, these replacement diaphragms get your PA system back to full power without buying an entire new driver. Built for sound engineers, venue operators, and mobile performers who need reliable repairs that don't break the budget.

Each titanium diaphragm delivers the same 102 dB sensitivity and crisp high-frequency response (1.5kHz to 20kHz) as your original driver. The 8-ohm impedance matches your existing crossover setup, while the 100-watt RMS power handling (200 watts peak) maintains the headroom you need for live sound applications.

Installation takes minutes with no soldering required — simply remove the old diaphragm and drop in the replacement. The titanium construction provides the durability and heat dissipation necessary for demanding live sound environments, from club systems running nightly to outdoor festival rigs pushed to their limits.

Perfect for maintaining line arrays, monitor wedges, and main PA systems where driver failure would otherwise sideline your entire rig. Whether you're running sound for a 200-person venue or managing inventory for a rental company, having spare diaphragms on hand prevents costly downtime during critical events.

This two-pack includes everything needed to service one driver with a backup spare. Each diaphragm weighs just 0.05 pounds, making them easy to keep in your repair kit. Backed by Seismic Audio's one-year warranty and fast shipping to get your system operational again.

Frequently Asked Questions

How do I know if I need to replace my compression driver diaphragm?

Common signs include distorted high frequencies, reduced output, crackling sounds, or complete loss of high-end from your horn-loaded speakers. If your compression driver was working fine and suddenly lost output or sounds harsh, the diaphragm has likely failed and needs replacement.

Are these diaphragms compatible with other brand compression drivers?

These diaphragms are specifically designed for Seismic Audio T-Driver compression drivers and may not fit other manufacturers' units. The mounting dimensions, voice coil diameter, and electrical specifications are matched to Seismic Audio drivers for proper fit and performance.

What tools do I need to replace the diaphragm?

You'll typically need a screwdriver to remove the driver from the horn and access screws to separate the diaphragm assembly. No soldering is required — the diaphragm connects with push-on terminals. The entire replacement process usually takes 10-15 minutes per driver.

Can I use just one diaphragm if only one driver failed?

Yes, you can replace a single failed diaphragm and keep the second as a spare. However, if you're running a stereo PA system or line array, consider replacing both diaphragms simultaneously to ensure matched performance and prevent the second one from failing shortly after.

Will replacing the diaphragm restore my driver to original performance?

A properly installed new diaphragm will restore your compression driver to factory specifications, including the full 100-watt RMS power handling and 1.5kHz-20kHz frequency response. This repair typically costs a fraction of buying a new compression driver while delivering identical performance.
