The SA-DR7 is designed for sound engineers, venue techs, and mobile performers who need to repair Peavey 14XT compression drivers without the cost of full driver replacement. This titanium diaphragm keeps your PA system running when high-frequency drivers fail during critical events.

This replacement diaphragm restores full high-frequency output to damaged compression drivers, delivering the same performance specifications as the original Peavey component. The titanium construction provides durability and consistent frequency response across the vocal range where clarity matters most.

Built to exact OEM specifications, the SA-DR7 features an 8-ohm impedance rating with a 71.35mm diameter and 34.4mm voice coil. Quick disconnect spade connectors ensure straightforward installation without soldering. The precision-matched dimensions guarantee proper fit and acoustic performance in compatible driver assemblies.

Use this diaphragm to repair drivers in Peavey PV-12M and PV-15M monitors, PR series mains, Impulse 100 systems, and TLS or SSE series speakers. Whether you're maintaining a church sound system, band PA, or venue installation, this replacement keeps your audio running instead of waiting for expensive driver replacements.

Installation requires basic tools and takes minutes with the spade connector design. Each diaphragm weighs just 0.06 pounds for easy handling during field repairs.

Seismic Audio backs the SA-DR7 with a one-year warranty and fast shipping. Keep spare diaphragms in your repair kit to minimize downtime when drivers fail.

Frequently Asked Questions

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

Common signs include distorted or missing high frequencies, crackling sounds during vocal passages, or complete loss of tweeter output. If your speaker sounds muffled or lacks presence, and the woofer still works normally, the compression driver diaphragm has likely failed. You can also gently remove the driver and visually inspect for torn or damaged diaphragm material.

Which Peavey speaker models use this SA-DR7 diaphragm?

The SA-DR7 is compatible with Peavey PV-12M and PV-15M floor monitors, PR-10, PR-12, and PR-15 mains, Impulse 100 systems, plus TLS and SSE series speakers. All these models use the same 14XT compression driver design. Check your speaker's model number or measure the existing diaphragm diameter to confirm compatibility before ordering.

Can I install this diaphragm myself or do I need a technician?

Most users can handle this repair with basic tools and mechanical skills. The quick disconnect spade connectors eliminate soldering requirements. You'll need to remove the compression driver from the cabinet, disassemble the driver housing, replace the diaphragm, and reassemble. Allow 30-45 minutes for the complete process if you're comfortable with speaker repair work.

How does replacing just the diaphragm compare to buying a new compression driver?

Diaphragm replacement costs significantly less than a new driver while delivering identical performance. The SA-DR7 uses the same titanium material and specifications as the original Peavey component. Unless the driver housing or magnet assembly is damaged, replacing just the diaphragm restores full functionality. Keep spare diaphragms on hand for quick field repairs during events.

Will this diaphragm handle the same power levels as the original Peavey part?

Yes, the SA-DR7 matches the original specifications exactly, including power handling and impedance ratings. The titanium construction provides the same durability and thermal characteristics as the OEM diaphragm. Your repaired driver will perform identically to a new Peavey unit, maintaining the same frequency response and maximum output levels in your PA system.
