The Quake 10 steel frame speaker drivers are built for musicians, sound engineers, and DIY builders who need reliable replacement woofers or want to construct custom PA cabinets. These 4-ohm drivers deliver the midrange punch and low-end response that live sound applications demand.

Each 10-inch driver handles 125 watts RMS and peaks at 250 watts, giving you headroom for dynamic performances without distortion. The 50-ounce magnet with 2.5-inch voice coil provides the magnetic force needed for tight bass response and clear midrange reproduction.

The pressed steel chassis resists flexing under power, while the paper cone delivers natural-sounding midrange frequencies. With 98dB sensitivity, these drivers produce substantial volume from moderate amplifier power. The 65Hz to 5kHz frequency response covers the fundamental range where most instruments and vocals live, making them effective for guitar cabinets, floor monitors, and mid-range duties in larger PA systems.

These woofers work well in custom guitar cabinets for bands, replacement drivers for existing PA speakers, or mid-range elements in DIY sound systems for churches and small venues. A pair can handle intimate venues up to 150 people when properly amplified and housed.

Each driver weighs 9 pounds and connects via standard speaker wire to any amplifier or powered mixer. The package includes two matched drivers ready for installation.

Seismic Audio backs these drivers with a one-year warranty and ships them ready to drop into your next audio project.

Frequently Asked Questions

What impedance amplifier do I need for these 4-ohm drivers?

These 4-ohm drivers work with any amplifier that can handle 4-ohm loads. When wiring both drivers in parallel, the total impedance drops to 2 ohms, so ensure your amplifier is stable at 2 ohms if connecting both to one channel. For separate channels or individual cabinets, any amp rated for 4-ohm operation will work properly.

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

Yes, these work as direct replacements for most 10-inch PA speakers, provided your cabinet was designed for similar frequency response. Check that your original drivers were 4-ohm impedance and similar power handling. The 65Hz-5kHz range makes them suitable for mid-range duties but not full-range reproduction without additional tweeters.

What size venues can a pair of these drivers handle?

In properly designed cabinets with adequate amplification, a pair can cover intimate venues up to 150 people. For larger crowds or outdoor events, you'll want additional drivers or subwoofers to extend low-end response. These work best as part of a larger PA system rather than standalone full-range speakers.

Do these drivers need crossovers or can I run them full-range?

These drivers can run full-range from an amplifier, but their 65Hz-5kHz response means you'll miss deep bass and high treble. For full-range applications, pair them with subwoofers below 80Hz and tweeters above 3kHz using appropriate crossovers. For guitar cabinets or dedicated mid-range duty, they work well without crossovers.

What connections and mounting hardware do I need?

These drivers connect via standard positive and negative speaker wire terminals. You'll need speaker wire appropriate for your amplifier's power output and cabinet depth sufficient for the 9-pound driver weight. Mounting requires eight screws in a standard 10-inch driver pattern. Hardware is not included, so source screws appropriate for your cabinet material and thickness.
