The Quake 15" replacement speaker drivers are built for DIY cabinet builders and repair techs who need reliable 15-inch woofers that deliver professional sound without the premium price. Whether you're building custom PA cabinets or replacing blown drivers in existing speakers, these drivers provide the foundation for solid live sound performance.

Each driver handles 250 watts RMS with 500-watt peak power handling, giving you enough headroom for demanding gigs without distortion. The 50-ounce magnet and 2.5-inch voice coil work together to move serious air while maintaining control across the frequency spectrum.

The 8-ohm impedance makes these drivers compatible with most amplifiers and mixing board setups, while the 95 dB sensitivity means you'll get good volume without needing massive power. The frequency response spans 50Hz to 5kHz, covering the fundamental range where most music lives. The pressed steel chassis provides durability for road use, and the paper cone delivers natural tone reproduction that works well for both music and speech.

These drivers work well in medium to large PA cabinets for bands, DJs, and permanent installations handling crowds of 100-400 people. They're equally suited for floor monitor builds or as the low-frequency foundation in multi-way speaker systems.

Each driver weighs 11 pounds and comes ready to install with standard mounting hardware compatibility. You receive two identical drivers with a one-year warranty and fast shipping from Seismic Audio.

Frequently Asked Questions

What size venue can I cover with speakers built using these drivers?

PA cabinets built with these drivers typically handle venues of 100-400 people, depending on your cabinet design and amplifier power. For outdoor events or larger crowds, you'll want multiple cabinets or additional subwoofer support. The 95 dB sensitivity and 250-watt RMS power handling provide good efficiency for medium-sized gigs.

Can I use these drivers to replace blown speakers in my existing PA cabinets?

Yes, these are direct replacements for most 15-inch, 8-ohm woofers in PA speakers, floor monitors, and bass cabinets. Check your current driver's mounting hole pattern and depth clearance before ordering. The pressed steel frame and standard dimensions fit most common cabinet designs from the past 20 years.

What amplifier power do I need to drive these drivers properly?

These drivers work best with amplifiers rated between 200-400 watts per channel at 8 ohms. Running less power won't damage them but may limit your headroom, while significantly exceeding the 250-watt RMS rating risks driver damage. Most powered mixers and rack-mount amplifiers in this range will drive them effectively.

Do I need to add a tweeter or horn when building cabinets with these drivers?

For full-range PA applications, yes – these drivers roll off at 5kHz, so you'll want to add a horn or tweeter for vocal clarity and cymbal detail. For subwoofer or bass guitar applications, these drivers work well on their own. Plan for a crossover around 2-3kHz when adding high-frequency components.

How do these compare to OEM replacement drivers from major speaker manufacturers?

These drivers offer comparable power handling and frequency response to OEM replacements at a fraction of the cost. While they may not have exotic cone materials or premium finishes, the 50-ounce magnet and robust steel frame provide reliable performance for professional applications. The one-year warranty backs up the build quality.
