The Seismic Audio Quake 12" speaker drivers are built for musicians, sound engineers, and DIY builders who need reliable replacement woofers or want to construct custom speaker cabinets. These professional-grade drivers deliver the power and frequency response needed for live sound applications.

Each 12" woofer handles 150 watts RMS and 300 watts peak power, providing the headroom necessary for dynamic live performances without distortion. The paper cone design produces natural midrange reproduction while the pressed steel chassis ensures durability under demanding conditions.

The 55Hz to 5kHz frequency response covers the fundamental range for vocals and most instruments, while the 8-ohm impedance makes these drivers compatible with virtually any amplifier or powered mixer. The 50-ounce magnet and 2.5" voice coil deliver 97dB sensitivity, meaning you get strong output without requiring excessive amplifier power. At 10 pounds each, these drivers provide substantial build quality without being unwieldy during installation.

Use these drivers for replacing blown woofers in existing PA cabinets, building custom speaker boxes for bands or DJs, or upgrading older sound systems in churches or small venues. Each pair can handle audiences up to 200 people when properly powered and housed.

The drivers come ready to install with standard mounting dimensions for 12" cutouts. You'll receive two matched drivers with a one-year warranty, plus Seismic Audio's direct customer support and fast shipping on replacement parts when you need them.

Frequently Asked Questions

What cabinet size do I need for these 12" drivers?

These drivers work best in cabinets with 1.5 to 3 cubic feet of internal volume, depending on whether you want sealed or ported design. For most live sound applications, a ported cabinet around 2.5 cubic feet will give you the best balance of low-end extension and efficiency. Make sure your cabinet has a standard 11.125" cutout diameter for proper mounting.

Can these drivers handle a full band without a subwoofer?

While these drivers extend down to 55Hz, they work best when paired with a subwoofer for full-range music reproduction. The 55Hz-5kHz response covers vocals, guitars, and most instruments well, but you'll want to high-pass them around 80Hz if you're adding a sub. For speech-only applications like churches or meetings, they can work standalone.

What amplifier power do I need to drive these properly?

With 97dB sensitivity, these drivers are efficient enough to work with amplifiers from 50 watts up to their 150-watt RMS rating. For most live sound applications, a 100-150 watt amplifier per driver provides good headroom. Don't exceed the 300-watt peak rating, as this can damage the voice coil.

Are these direct replacements for other 12" woofers?

These drivers use standard 12" mounting dimensions and will physically fit most cabinets designed for 12" speakers. However, the frequency response and power handling may differ from your original drivers, which could change the sound characteristics. Check your cabinet's recommended specifications before replacing drivers from other manufacturers.

How do these compare to the drivers in Seismic Audio's powered speakers?

These are the same quality drivers used in many of Seismic Audio's passive PA speakers. They're designed for the same professional applications but give you the flexibility to build custom cabinets or replace damaged drivers. The main difference is that you'll need to provide your own amplification and crossover components.
