The Quake 15 Sub is a heavy-duty 15" subwoofer driver designed for DIY speaker builders, repair shops, and sound engineers replacing blown drivers in existing cabinets. This raw driver delivers the low-frequency foundation needed for live sound reinforcement, DJ setups, and permanent installations.

Built around a 70-ounce magnet and 3" voice coil, the Quake 15 Sub handles 500 watts RMS and peaks at 1000 watts, providing the power handling needed for demanding live sound applications. The 30Hz-2.5kHz frequency response extends deep into sub-bass territory while maintaining clarity through the critical low-mid range.

The pressed steel chassis provides structural integrity under high excursion, while the paper cone delivers natural-sounding bass reproduction. At 8 ohms impedance and 90dB sensitivity, this driver integrates easily into most cabinet designs and amplifier configurations. The robust construction handles the thermal and mechanical stress of extended high-volume use.

Perfect for building custom subwoofer cabinets for bands, DJs, or venues up to 500 people, or replacing damaged drivers in existing PA systems. The driver also works well in bass guitar cabinets and home audio subwoofer projects where deep, powerful bass is required.

No connections or cables required – this is a raw driver that mounts directly into your cabinet with standard hardware. Installation requires basic woodworking skills and appropriate cabinet design for optimal performance.

Backed by Seismic Audio's one-year warranty with fast shipping. Professional-grade driver construction at a price point that makes custom builds and repairs economically viable.

Frequently Asked Questions

What size cabinet do I need for the Quake 15 Sub?

Cabinet design depends on your intended application, but a typical sealed subwoofer enclosure requires 2-4 cubic feet internal volume, while ported designs need 3-6 cubic feet. The driver's Thiele-Small parameters work well in both sealed and ported configurations. Proper cabinet tuning is essential for optimal performance and driver protection.

Can I replace my existing 15" subwoofer driver with the Quake 15 Sub?

Yes, as long as your current driver is 15" with 8-ohm impedance and your amplifier provides 500 watts RMS or less. Check that your cabinet's mounting depth accommodates the Quake 15 Sub's magnet assembly. Most standard 15" subwoofer cabinets will accept this driver without modification.

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

The driver handles 500 watts RMS, so an amplifier rated between 300-500 watts RMS at 8 ohms provides optimal performance. Using less power is fine but may limit maximum output. Never exceed 500 watts RMS continuous power, though brief peaks up to 1000 watts are acceptable.

How low will the Quake 15 Sub play in a properly designed cabinet?

The 30Hz frequency response extends well into sub-bass territory, providing deep, powerful low-end suitable for electronic music, hip-hop, and modern rock. In a properly tuned ported enclosure, usable output extends to around 25-28Hz, while sealed cabinets typically roll off more gradually below 35Hz.

Is this driver suitable for bass guitar cabinets?

While designed primarily as a subwoofer driver, the Quake 15 Sub can work in bass guitar applications requiring deep, powerful low-end. However, its 2.5kHz high-frequency limit means you'll need a tweeter or midrange driver for full-range bass guitar reproduction. It excels as a dedicated low-frequency driver in multi-way bass systems.
