The Quake 15 is a replacement woofer driver designed for sound engineers, cabinet builders, and venues looking to repair or upgrade existing PA systems. This 15-inch driver delivers the low-frequency foundation needed for live sound reinforcement.

Built with a robust 50-ounce magnet and 2.5-inch voice coil, the Quake 15 handles 250 watts RMS and peaks at 500 watts. The pressed steel chassis provides durability for touring rigs and permanent installations, while the paper cone delivers natural midrange reproduction alongside solid bass response.

With 95 dB sensitivity and 8-ohm impedance, this driver works efficiently with most PA amplifiers and integrates easily into existing speaker systems. The 50-5K Hz frequency response covers the essential low and midrange content for vocals, instruments, and playback music. At 8 pounds, the Quake 15 offers substantial magnetic structure without excessive weight.

Use this driver for repairing blown PA speakers, building custom cabinets for bands and DJs, or upgrading older sound systems in churches and venues. The 8-ohm impedance matches standard PA configurations, making it suitable for systems serving audiences from small clubs to outdoor events up to 200 people when paired with appropriate amplification.

The driver comes ready to install with standard mounting hardware compatibility. Each Quake 15 includes a one-year warranty and ships with Seismic Audio's reliable customer support for technical questions.

Technical Specifications

Frequently Asked Questions

Will this driver fit my existing PA cabinet?

The Quake 15 uses standard 15-inch mounting dimensions that fit most PA cabinets designed for 15-inch drivers. Check your cabinet's mounting hole pattern and depth clearance before ordering. The 8-pound weight and pressed steel frame work with typical PA enclosure designs.

What size venue can this driver handle?

When properly amplified and housed in an appropriate cabinet, the Quake 15 can serve venues up to 200 people for background music or speech reinforcement. For live bands or DJ applications, pair multiple cabinets or add subwoofers for larger crowds and higher SPL requirements.

What amplifier power should I use with this driver?

Match this driver with amplifiers delivering 200-400 watts RMS at 8 ohms for optimal performance. The 250-watt RMS rating means you can safely drive it with most mid-range PA amplifiers without risk of thermal damage when properly ventilated in a cabinet.

Can I use this as a standalone speaker without a cabinet?

No, the Quake 15 requires installation in a properly designed speaker cabinet to perform correctly. Raw drivers need enclosures to control airflow, protect the cone, and achieve proper frequency response. The driver alone will produce very little bass output.

How does this compare to buying a complete PA speaker?

The Quake 15 costs less than complete speakers but requires cabinet construction or existing enclosure repair skills. Choose this driver for repairs, custom builds, or upgrades. Buy complete PA speakers if you need ready-to-use sound reinforcement without modification work.
