When your PA speaker blows a driver mid-gig, or you're building custom cabinets for your band's sound system, the Quake 15 gives you a solid replacement option that won't break the bank. This 15-inch woofer handles the low-end foundation you need for live sound — whether you're fixing a blown driver in your existing rig or putting together a custom PA setup from scratch.

The build quality hits the sweet spot for working musicians. That 50-ounce magnet and 2.5-inch voice coil can take 250 watts RMS without complaining, while the pressed steel frame survives the load-ins and tear-downs that kill cheaper drivers. The paper cone gives you natural midrange response alongside the bass punch, so vocals cut through without sounding harsh or artificial.

With 95 dB sensitivity and 8-ohm impedance, this driver plays nice with most PA amps you'll find in clubs and small venues. The 50Hz-5kHz frequency response covers the meat of your mix — kick drums, bass guitar, vocal fundamentals, and acoustic guitar body. It's not trying to be a full-range solution, which is honest. Pair it with a decent tweeter or horn for complete coverage.

This driver works for bands building their own PA, sound companies doing repairs, or venues upgrading older systems. You're looking at coverage for audiences up to 200 people when you've got appropriate amplification and cabinet design. It's not a stadium driver, but it'll handle your typical club, church, or outdoor festival booth without drama.

**Bottom line:** The Quake 15 is a dependable workhorse driver for PA repairs and custom builds — nothing fancy, but it does the job at a price point that makes sense for working musicians.

Frequently Asked Questions

Will this fit my blown PA speaker?

The Quake 15 uses standard 15-inch mounting dimensions that work with most PA cabinets designed for 15-inch drivers. Measure your cabinet's mounting holes and check the depth clearance before ordering. The 8-pound weight and steel frame work with typical PA enclosure designs, but every cabinet is different.

What kind of power do I need to drive this properly?

You'll want an amp pushing 200-400 watts RMS at 8 ohms for best results. The 250-watt RMS rating means most mid-range PA amplifiers will drive it safely without thermal damage, as long as your cabinet has decent ventilation. Don't underdrive it with a tiny amp — it needs some juice to come alive.

Can I use this driver by itself without a cabinet?

Absolutely not. Raw drivers need proper enclosures to work — the cabinet controls airflow and gives you actual bass response. Without a cabinet, you'll get almost no low end and the driver will sound thin and lifeless. If you need plug-and-play, buy a complete PA speaker instead.

How loud will this get for live shows?

In a properly designed cabinet with adequate amplification, you're looking at coverage for venues up to 200 people for background music or speech. For live bands or DJ work, you'll want multiple cabinets or add subwoofers for bigger crowds and higher volume requirements. One 15-inch driver has its limits.
