The Seismic Audio Quake 12 is built for musicians, sound engineers, and DIY builders who need a reliable replacement driver or want to build custom PA cabinets from scratch. This 12-inch woofer delivers the low-end punch and midrange clarity that live sound applications demand.

With 150 watts RMS power handling and 300 watts peak capacity, this driver provides the headroom needed for dynamic live performances without distortion. The 55Hz-5kHz frequency response covers the essential vocal and instrument range, while 97dB sensitivity ensures efficient power transfer from your amplifier.

The pressed steel chassis and 50-ounce magnet create a stable platform for the 2.5-inch voice coil, resulting in tight bass response and clear midrange reproduction. At 16 ohms impedance, this driver works well in series wiring configurations for multi-driver cabinets or as a direct replacement for blown speakers in existing PA systems.

Perfect for building custom floor monitors, replacing damaged drivers in band PA systems, or constructing specialized cabinets for churches and venues. The robust construction handles the rigors of mobile DJ setups and touring applications where reliability matters.

Installation requires standard speaker terminals and appropriate gauge speaker wire. Each driver weighs 10 pounds and ships ready to mount in your cabinet.

Backed by Seismic Audio's one-year warranty and fast shipping, the Quake 12 gives you professional-grade components at a price that makes sense for working musicians and sound professionals.

Technical Specifications

Frequently Asked Questions

What size cabinet do I need for this 12-inch driver?

Cabinet design depends on your intended use, but most PA applications work well with 1.5 to 2.5 cubic foot enclosures. For floor monitors, smaller sealed boxes around 1 cubic foot provide tight response. Always calculate port dimensions if building a ported design, as improper tuning can damage the driver.

Can I wire multiple Quake 12 drivers together in one cabinet?

Yes, the 16-ohm impedance makes series wiring straightforward. Two drivers in series give you 32 ohms total, while parallel wiring drops to 8 ohms. Most amplifiers handle 8-ohm loads well, but check your amp's minimum impedance rating before parallel wiring.

Will this driver work as a replacement in my existing PA speaker?

The Quake 12 can replace most 12-inch drivers if the mounting hole pattern matches and the impedance is compatible. Measure your cabinet's baffle cutout and bolt hole spacing before ordering. The 16-ohm impedance may change your cabinet's total load if replacing an 8-ohm driver.

What amplifier power do I need to drive this speaker effectively?

Aim for 75-150 watts RMS per driver for optimal performance. Under-powering can cause distortion at higher volumes, while exceeding 300 watts peak can damage the voice coil. A quality 100-watt amplifier provides plenty of clean headroom for most live sound applications.

How does this compare to the 8-ohm version of the same driver?

Both versions share identical power handling, frequency response, and construction. The 16-ohm model offers more flexibility for series wiring in multi-driver cabinets, while 8-ohm drivers are more common for single-driver applications. Choose based on your amplifier's impedance requirements.
