Quake 15 Sub 15" Steel Frame Subwoofer Driver (Pair) 8 Ohm
The Quake 15 Sub drivers are built for sound professionals who need reliable 15-inch subwoofer replacement drivers or want to build custom subwoofer cabinets. These raw drivers deliver the low-end foundation for PA systems, DJ rigs, and live sound setups.
Each driver handles 500 watts RMS and peaks at 1000 watts, providing the power handling needed for demanding live sound applications. The 30Hz to 2.5kHz frequency response ensures deep bass extension while maintaining clarity in the low-midrange frequencies that give kick drums and bass guitars their punch.
The pressed steel chassis provides structural integrity under high power loads, while the 70-ounce magnet and 3-inch voice coil work together to deliver controlled bass response. At 8 ohms impedance and 90dB sensitivity, these drivers pair well with most pro audio amplifiers and can be wired in various configurations to match your system requirements.
Use these drivers to rebuild blown subwoofers, upgrade existing cabinets, or construct custom sub enclosures for medium to large venues. They're suitable for clubs, outdoor events, and installations where deep, controlled bass is essential for music reproduction.
You'll receive two identical drivers ready for installation. Standard speaker wire connections make integration straightforward with any amplifier or powered mixer setup.
Seismic Audio backs these drivers with a one-year warranty. Each driver weighs 13 pounds, reflecting the robust construction needed for professional applications.

Frequently Asked Questions
What amplifier power do I need for these subwoofer drivers?
Match your amplifier to the 500-watt RMS rating for optimal performance. You can use amplifiers from 300-600 watts RMS at 8 ohms without damaging the drivers. Higher-powered amps provide more headroom, but avoid sustained operation beyond the RMS rating to prevent voice coil damage.
Can I wire these drivers together for different impedance loads?
Yes, you can wire the pair in series for 16 ohms total or parallel for 4 ohms total. Series wiring reduces power handling but works well with high-impedance amplifier outputs. Parallel wiring doubles the power handling but requires amplifiers stable at 4 ohms.
What size enclosure do these drivers need?
These drivers work best in ported or bandpass enclosures between 3-6 cubic feet internal volume. The specific tuning frequency and port design depend on your target frequency response. Sealed enclosures should be 2-4 cubic feet for tight, controlled bass response.
Will these work as replacements in my existing subwoofer cabinet?
These drivers will fit most standard 15-inch subwoofer cutouts, but verify your cabinet's internal volume and port tuning match these drivers' parameters. The mounting depth and magnet clearance should also be checked, as the 70-ounce magnet requires adequate rear clearance.
What venues can these drivers handle?
A pair of these drivers in properly designed enclosures can provide bass for venues up to 200-300 people, depending on music style and room acoustics. For larger venues or outdoor events, consider multiple subwoofer cabinets to maintain even bass coverage throughout the listening area.
