15" PA/DJ Raw SubWoofer/Speaker Replacement PRO Audio

When you're staring at a blown 15" driver in your sub cabinet an hour before load-in, you need a replacement that drops right in and gets you back to moving air. The Quake 15 Sub is exactly that — a heavy-duty raw driver built for the realities of live sound, DJ setups, and custom builds where you need real low-end extension without breaking the bank.

The numbers tell the story: 70-ounce magnet, 3" voice coil, and 500 watts RMS handling means this driver won't fold under pressure when your bassist is digging into those low B notes or the kick drum is pounding through a dense mix. That 30Hz-2.5kHz response gets you proper sub-bass reach while covering the critical low-mids that make bass guitar and kick drum cut through. The pressed steel chassis handles high excursion without flexing, and the paper cone gives you that natural bass reproduction that doesn't sound synthetic or overly processed.

At 8 ohms and 90dB sensitivity, it plays nice with most amplifiers and cabinet designs. Whether you're building a custom sub array for your band's PA, replacing a dead driver in an existing cabinet, or putting together a DJ system that needs to fill a dance floor, this driver delivers the foundation your mix needs. It's not trying to be a full-range solution — this is a dedicated low-frequency workhorse that does one job very well.

Bottom line: If you need deep, powerful bass reproduction for live sound applications and want a reliable driver that won't quit on you, the Quake 15 Sub delivers professional-grade low-end at a price that makes sense for working musicians.

Frequently Asked Questions

What cabinet size do I need for optimal performance?

For sealed enclosures, plan on 2-4 cubic feet internal volume. Ported designs typically need 3-6 cubic feet and proper port tuning to match the driver's parameters. The specific volume depends on whether you want tight, punchy bass (smaller sealed) or maximum low-end extension (larger ported). Most standard 15" subwoofer cabinets will work with this driver.

Can I drop this into my existing blown 15" sub cabinet?

Most likely, yes — as long as your current driver was 8-ohm and your amp puts out 500 watts RMS or less. Check the mounting depth to make sure that 70-ounce magnet assembly clears your cabinet's back wall. Standard 15" mounting holes and bolt patterns are universal, so installation is usually straightforward.

How much amplifier power do I actually need?

You'll get the best performance with 300-500 watts RMS at 8 ohms. Less power is fine but limits your maximum output — which might be perfect if you're not trying to rattle windows. Don't continuously push more than 500 watts RMS, though brief peaks up to 1000 watts won't hurt it.

Will this work for bass guitar cabinets?

It can, but with limitations. The 2.5kHz rolloff means you'll lose the midrange definition that makes bass guitar cut through a mix. It's excellent as the low-frequency component in a multi-way bass system, but you'd need a separate mid/high driver for full-range bass guitar reproduction. Great for that deep, fundamental low-end though.
