The Quake 15 steel frame speaker drivers are built for musicians, sound engineers, and venue operators who need reliable replacement woofers or want to build custom speaker cabinets. These 16-ohm drivers deliver the low-frequency foundation your PA system depends on.

Each 15-inch woofer handles 200 watts RMS and peaks at 400 watts, giving you the headroom needed for live performance without distortion. The 50-ounce magnet and 2.5-inch voice coil provide the magnetic strength to move serious air and deliver punchy bass response.

The frequency response spans 50Hz to 5kHz with 95dB sensitivity, making these drivers efficient enough to work with most amplifiers while covering the critical low-mid range that gives vocals and instruments their body. The pressed steel chassis withstands the rigors of regular transport and setup, while the paper cone delivers natural tone without harshness.

These drivers work well in clubs, small theaters, and outdoor events for crowds up to 200-300 people when properly amplified. They're also popular for replacing blown drivers in existing cabinets or building custom monitor wedges. Each driver weighs 11 pounds and fits standard 15-inch mounting holes.

You receive both drivers ready to install – no additional components needed beyond your cabinet and amplifier. Standard speaker wire connects directly to the terminals.

Seismic Audio backs each pair with a one-year warranty and ships nationwide. Professional-grade components at a price that works for working musicians.

Frequently Asked Questions

What size venue can these 15-inch drivers handle?

When properly amplified and housed in appropriate cabinets, these drivers work well for indoor venues up to 200-300 people or smaller outdoor events. The 200-watt RMS power handling and 95dB sensitivity provide sufficient output for clubs, churches, school auditoriums, and mobile DJ setups. For larger venues, consider multiple cabinets or adding subwoofers for extended low-frequency coverage.

Can I use these drivers to replace blown woofers in my existing speakers?

Yes, these are designed as direct replacement drivers for most 15-inch PA speakers with 16-ohm impedance. Check your cabinet's impedance rating and mounting hole diameter before ordering. The pressed steel frame fits standard 15-inch mounting patterns, and the 50Hz-5kHz frequency response matches most PA applications. Weight is 11 pounds each, similar to most comparable drivers.

What amplifier power do I need to drive these speakers properly?

These 16-ohm drivers work best with amplifiers providing 100-200 watts RMS per channel. The 95dB sensitivity means they're efficient enough to get good volume from moderate power levels. You can safely use up to 400 watts peak power, but most applications work well with 150-watt amplifiers. Higher impedance means you can wire multiple drivers together more easily.

Do these drivers include crossovers or do I need to add them?

These are raw drivers only – no crossovers, cabinets, or mounting hardware included. You'll need to provide your own crossover network if building a multi-way system, or use them in cabinets that already have crossovers installed. For full-range PA use, many builders add a passive crossover around 3-4kHz to blend with compression drivers or tweeters.

What gauge speaker wire should I use with these 16-ohm drivers?

Use 14-gauge speaker wire for runs up to 50 feet, or 12-gauge for longer distances. The higher 16-ohm impedance is more forgiving of wire resistance than 8-ohm drivers, making them suitable for longer cable runs without significant power loss. Standard banana plugs or bare wire connections work with the terminal posts – no special connectors required.
