These 15-inch steel frame woofers are essential for DIY cabinet builders and sound engineers replacing blown drivers in PA systems. The Quake 15 pair delivers the low-end foundation that live sound applications demand.

Each driver handles 200 watts RMS with 400 watts peak power handling, providing the headroom needed for dynamic program material without distortion. The 50-ounce magnet structure with 2.5-inch voice coil ensures consistent performance under continuous use.

The 4-ohm impedance works efficiently with most professional amplifiers, while the 50Hz to 5KHz frequency response covers the critical midrange and upper bass frequencies where vocals and instruments sit in the mix. At 95dB sensitivity, these drivers convert amplifier power efficiently into acoustic output. The pressed steel chassis provides durability for touring applications, and the paper cone design offers natural tone characteristics favored in live sound reinforcement.

These woofers work well for building custom PA cabinets for bands, replacing drivers in existing 15-inch cabinets, or constructing floor monitors for stages up to medium venue sizes. Each driver weighs 11 pounds, reflecting the robust magnet structure needed for professional applications.

Installation requires standard speaker wire connections - no special cables needed. You receive two matched drivers ready for cabinet installation.

Seismic Audio backs these drivers with a one-year warranty and ships them ready to perform in your next sound system build.

Frequently Asked Questions

What size venues can I cover with a pair of these 15-inch drivers?

When properly housed in efficient cabinets and powered adequately, a pair of these Quake 15 drivers can handle small to medium venues up to 200-300 people. For larger crowds or outdoor events, you'll want to add subwoofers or additional cabinets to maintain proper coverage and headroom.

Can I replace existing drivers in my PA cabinets with these?

Yes, these are standard 15-inch replacement woofers that fit most PA cabinet cutouts. Verify your existing drivers are also 4-ohm impedance for proper amplifier matching. The mounting bolt pattern and magnet clearance work with typical 15-inch PA cabinet designs.

What amplifier power do I need to drive these speakers?

These drivers work well with amplifiers delivering 150-300 watts RMS per channel into 4 ohms. Running significantly under-powered risks clipping distortion, while excessive power can damage the voice coils. Match your amplifier's 4-ohm output rating to the 200-watt RMS handling for optimal performance.

Do I need a crossover network with these drivers?

Yes, you'll need a crossover to limit frequencies sent to these drivers since they roll off around 5KHz. Use an active crossover or passive network to send frequencies above 2-3KHz to compression drivers or tweeters for full-range PA applications.

How do these compare to 8-ohm versions of the same driver?

The 4-ohm impedance draws more current from your amplifier, potentially delivering more power if your amp can handle the load. Most professional amplifiers produce higher wattage into 4 ohms versus 8 ohms, making these drivers suitable for applications requiring maximum output from your existing amplifier.
