The Quake 12" Steel Frame Speaker Driver delivers professional-grade replacement woofers for DIY cabinet builders and technicians repairing existing PA systems. These 16-ohm drivers handle the demanding midrange and low-frequency reproduction that live sound applications require.

Each driver delivers 150 watts RMS and 300 watts peak power handling through a robust 50oz magnet and 2.5" voice coil design. The pressed steel chassis provides the structural integrity needed for high-volume applications while maintaining consistent performance under stress.

The 55Hz to 5kHz frequency response covers the essential vocal and instrumental range with 97dB sensitivity, ensuring efficient power conversion whether you're running modest or high-powered amplifiers. The 16-ohm impedance makes these drivers suitable for series wiring configurations or specific cabinet designs that require higher impedance loads.

These drivers work well in floor monitors for bands, replacement woofers in church sound systems, or custom PA builds for mobile DJs working venues up to 200 people. The paper cone construction delivers the warm, punchy low-end that live sound engineers prefer for vocal intelligibility and instrument clarity.

Installation requires standard speaker wire connections - no special cables needed. Each driver weighs 10 pounds, so factor that into your cabinet design for proper bracing and handling.

Seismic Audio backs these drivers with a one-year warranty and ships them ready to install. Professional performance at a price point that makes sense for working musicians and sound technicians.

Frequently Asked Questions

What size venues can I cover with a pair of these 12" drivers?

A pair of Quake 12" drivers in properly designed cabinets can handle indoor venues up to 200 people or outdoor gatherings up to 150 people when paired with adequate amplification. For larger crowds, you'll want to add a subwoofer or use multiple cabinets to maintain sound quality and coverage.

Can I wire these 16-ohm drivers to work with my 8-ohm amplifier?

Yes, you can wire two 16-ohm drivers in parallel to create an 8-ohm load that matches most amplifiers perfectly. This parallel wiring also doubles your power handling to 300 watts RMS total. Make sure your cabinet design accounts for the acoustic interaction between drivers.

Do these drivers need a crossover network to sound good?

These drivers work best with a passive crossover that rolls off frequencies above 3-4kHz to prevent harsh highs and protect the paper cone. If you're building a full-range cabinet, plan to add a tweeter with an appropriate crossover network for frequencies above 5kHz.

How do these compare to the 8-ohm version of the same driver?

The 16-ohm version gives you more flexibility for series wiring and higher-impedance amplifier matching, but the 8-ohm version typically provides slightly more power transfer efficiency with standard amplifiers. Choose based on your specific amplifier impedance requirements and cabinet design goals.

What type of cabinet construction works best with these drivers?

These drivers perform well in sealed, ported, or bandpass enclosures between 2-4 cubic feet internal volume. The pressed steel chassis requires solid mounting with at least 8 screws and proper gasket sealing. Avoid overly lightweight cabinets that can't handle the 10-pound driver weight and power output.
