The Quake 6 is a 6-inch replacement woofer designed for DIY speaker builders and sound engineers repairing existing PA cabinets. This steel-frame driver handles the critical midrange frequencies that define vocal clarity and instrument presence in live sound applications.

Built around a 30-ounce magnet and 1.5-inch voice coil, the Quake 6 delivers 50 watts RMS power handling with 100-watt peak capacity. The paper cone construction provides natural midrange response, while the pressed steel chassis ensures consistent performance under demanding conditions.

Operating at 8-ohm impedance with 95 dB sensitivity, this driver covers 500Hz to 5kHz frequency response—the essential range for vocals and lead instruments. At 4 pounds, the Quake 6 fits standard 6-inch mounting patterns found in most PA speaker cabinets and monitor enclosures.

Perfect for building custom PA speakers, replacing blown drivers in existing cabinets, or constructing floor monitors for small venues and rehearsal spaces. This driver works well in 2-way systems paired with compression drivers or in monitor wedges for stages accommodating up to 150 people.

Installation requires standard speaker wire connections to amplifier outputs or passive crossover networks. No additional hardware included—mounting screws sold separately.

Seismic Audio backs the Quake 6 with a one-year warranty and fast shipping. Professional-grade components at a price point that makes sense for working musicians and sound technicians building reliable PA systems.

Frequently Asked Questions

What size venues can I use the Quake 6 in?

The Quake 6 works best in small to medium venues up to 150 people when used in properly designed cabinets. Its 50-watt RMS power handling and 95 dB sensitivity make it suitable for coffee shops, small clubs, rehearsal rooms, and house of worship spaces. For larger venues, consider multiple cabinets or higher-wattage drivers.

Can I replace any 6-inch speaker with the Quake 6?

The Quake 6 fits standard 6-inch mounting patterns, but check your cabinet's impedance requirements first. This is an 8-ohm driver, so verify your amplifier and crossover are designed for 8-ohm loads. The mounting depth and magnet clearance should also be confirmed before installation.

What cables do I need to connect the Quake 6?

You'll need standard speaker wire (16-gauge minimum recommended) to connect from your amplifier or crossover network to the driver terminals. The Quake 6 doesn't include mounting screws or wire—these are sold separately. Use appropriate gauge wire for your power levels and cabinet size.

Do I need a crossover with the Quake 6?

Yes, the Quake 6's 500Hz-5kHz response range means it's designed for use with a crossover in multi-way systems. Pair it with tweeters or compression drivers for full-range response, or use it as a dedicated midrange driver. Running it full-range without high-frequency protection may limit your system's vocal clarity.

How does the Quake 6 compare to larger woofers for PA use?

The Quake 6 excels at midrange reproduction but won't provide the low-end response of 10-inch or 12-inch woofers. It's ideal for monitor wedges, satellite speakers in PA systems with separate subwoofers, or as midrange drivers in 3-way designs. For full-range PA speakers, consider larger Seismic Audio drivers with extended low-frequency response.
