The Quake 15 Sub is a robust 15-inch replacement driver designed for DIY subwoofer builds and speaker repairs. This steel-frame woofer delivers the low-frequency foundation that live sound systems and DJ setups demand.

Built around a 70-ounce magnet with a 3-inch voice coil, this driver handles 500 watts RMS (1000 watts peak) while maintaining clean bass response down to 30 Hz. The pressed steel chassis provides the structural integrity needed for high-output applications, while the paper cone delivers punchy low-end without muddy overtones.

The 4-ohm impedance matches most pro audio amplifiers and powered subwoofer plates. At 90 dB sensitivity, it converts amplifier power efficiently into sound pressure. The frequency response extends from 30 Hz to 2.5 kHz, making it suitable for dedicated subwoofer applications where a crossover handles frequency division.

Perfect for building custom subwoofer enclosures for bands, mobile DJs, or permanent installations in churches and venues handling up to 200 people. Also serves as a direct replacement for blown drivers in existing subwoofer cabinets. Works with any amplifier or powered plate that can deliver 4-ohm loads.

Standard push terminals accept bare wire or spade connectors. One driver included per purchase.

Seismic Audio backs the Quake 15 Sub with a one-year warranty. At 13 pounds, this driver ships fast and installs easily in properly designed enclosures.

Technical Specifications

Frequently Asked Questions

What amplifier power do I need for the Quake 15 Sub?

This driver handles 500 watts RMS, so an amplifier delivering 300-600 watts into 4 ohms will work well. Using less power won't damage the driver but may limit your maximum output. Amplifiers significantly over 600 watts require careful gain management to prevent damage.

What size venue will this subwoofer driver cover?

In a properly designed enclosure, the Quake 15 Sub can provide bass reinforcement for venues up to 200 people. For outdoor events or larger spaces, you'll want multiple drivers or supplemental subwoofers to maintain adequate low-frequency coverage.

Can I use this to replace a blown driver in my existing subwoofer?

Yes, if your current subwoofer uses a 15-inch, 4-ohm driver with similar power handling. Check your cabinet's original specifications to ensure the Quake 15 Sub matches the impedance and power requirements. The mounting depth and magnet clearance should also be verified before installation.

What type of enclosure works best with this driver?

The Quake 15 Sub works well in vented (ported) enclosures designed for subwoofer applications. Sealed enclosures will also work but may require more power for the same output. Follow established subwoofer design principles or use speaker design software to calculate the optimal box dimensions for your application.

Do I need a crossover with this driver?

Yes, this driver's frequency response extends to 2.5 kHz, but for subwoofer use, you'll want to cross it over between 80-120 Hz using an active crossover or the crossover in your powered mixer. This prevents the driver from reproducing midrange frequencies and ensures clean bass reproduction.
