Quake 15 Sub 15" Steel Frame Subwoofer Driver - 8 Ohm

When your sub driver blows mid-gig or you're building custom cabinets for your PA rig, the Quake 15 Sub drivers give you serious low-end muscle without breaking the bank. These aren't boutique woofers with exotic materials — they're workhorses built for the kind of punishment live sound dishes out night after night.

Each driver handles 500 watts RMS with 1000-watt peaks, which means you can push them hard when that drop hits without worrying about voice coil damage. The 30Hz to 2.5kHz response gives you that chest-thumping sub bass while still handling the low-mid punch that makes kick drums cut through a dense mix. The pressed steel frame and 70-ounce magnet aren't glamorous, but they're what keeps these drivers moving air when you're running them at club volumes.

At 8 ohms and 90dB sensitivity, these play nice with most power amps and give you flexibility in wiring configurations. Whether you're replacing blown drivers in existing cabs or building new enclosures from scratch, the standard mounting pattern fits most 15-inch cutouts. These aren't high-end studio monitors — they're designed for the real world where consistent, controlled bass matters more than audiophile specs.

If you're running a mobile DJ setup, small-to-medium venue sound, or need reliable backup subs, a pair of these in the right cabinets will cover rooms up to a couple hundred people. They won't shake stadium foundations, but they'll give you the low-end foundation your mix needs without the premium price tag.

**Bottom line:** Solid replacement or build-your-own drivers for working musicians who need reliable sub-bass coverage without exotic pricing — they do the job and keep doing it.

Frequently Asked Questions

What amp power should I run with these drivers?

Aim for 300-600 watts RMS at 8 ohms — the 500-watt RMS rating is your sweet spot. More powerful amps give you headroom for transients, but don't sustain operation above the RMS rating unless you want to cook the voice coils. Under-powering is usually safer than over-driving.

Can I wire both drivers to change the impedance load?

Yes — series wiring gives you 16 ohms total, parallel gives you 4 ohms. Series reduces power handling but works with amps that prefer higher impedance loads. Parallel doubles your power handling but make sure your amp is stable at 4 ohms or you'll have bigger problems than blown drivers.

Will these fit my existing subwoofer cabinet?

They'll physically fit most 15-inch cutouts, but check your cabinet's internal volume and port tuning first. These drivers have specific enclosure requirements — wrong box volume or tuning frequency will kill your bass response. Also measure magnet clearance; that 70-ounce magnet needs rear space.

What size venues can a pair handle?

In properly designed enclosures, these will cover 200-300 people depending on the room and music style. Electronic music or hip-hop in a concrete room? You'll need more subs. Acoustic or folk in a carpeted space? These might be overkill. For larger outdoor gigs, plan on multiple cabinets for even coverage.
