The Quake 8 replacement driver serves musicians, sound engineers, and DIY builders who need a reliable 8-inch woofer for custom PA builds or speaker repairs. This steel-frame driver handles the demanding midrange and low-frequency reproduction that forms the backbone of live sound systems.

Built around a robust pressed steel chassis, the Quake 8 delivers 100 watts RMS power handling with peaks up to 200 watts. The 35-ounce magnet and 2-inch voice coil provide the magnetic strength needed for consistent performance under stage volume demands.

The 55Hz to 5kHz frequency response covers the critical vocal and instrument range that cuts through a mix, while the 94dB sensitivity ensures efficient power conversion from your amplifier. At 8 ohms impedance, this driver integrates easily with most PA amplifiers and crossover networks. The paper cone construction delivers natural midrange reproduction without the harshness of some synthetic materials.

Whether you're building a custom monitor wedge for your band, repairing a blown driver in your church's PA system, or constructing a multi-way speaker cabinet for mobile DJ work, the Quake 8 handles small to medium venues up to 200 people. The driver works well in ported or sealed enclosures depending on your application.

Installation requires standard speaker wire connections to your amplifier or crossover network. Each driver ships ready to install with mounting hardware included. Seismic Audio backs the Quake 8 with a one-year warranty and fast shipping to get your sound system back online quickly.

Frequently Asked Questions

What size venues can the Quake 8 handle?

The Quake 8 works well for small to medium venues up to 200 people when properly amplified and housed in an appropriate cabinet. For larger venues, consider multiple drivers or higher-powered models. The 100-watt RMS handling and 94dB sensitivity provide adequate output for coffee shops, small clubs, churches, and outdoor gatherings.

Can I use this driver to replace a blown speaker in my existing PA cabinet?

Yes, as long as your cabinet was designed for an 8-inch driver with 8-ohm impedance. Check your original speaker's mounting hole pattern and depth clearance before ordering. The Quake 8 fits standard 8-inch mounting configurations and works with most passive crossover networks designed for similar frequency ranges.

What type of amplifier and cables do I need?

The Quake 8 requires an external amplifier capable of delivering up to 100 watts RMS into 8 ohms. Connect using standard 12 or 14-gauge speaker wire with banana plugs, spade connectors, or bare wire depending on your amplifier's outputs. The driver has standard positive and negative terminals for easy hookup.

Do I need a tweeter with this driver for full-range sound?

For full-range PA applications, yes. The Quake 8's 5kHz upper limit means you'll want to add a tweeter or compression driver for frequencies above 5kHz to maintain vocal clarity and instrument presence. For bass-heavy applications or subwoofer use, the Quake 8 can work alone with appropriate crossover filtering.

How does this compare to the next size up?

Compared to 10-inch or 12-inch drivers, the Quake 8 offers faster transient response and fits in more compact cabinets, making it ideal for monitor wedges and portable systems. Larger drivers typically provide more bass extension and higher output levels for bigger venues, but the 8-inch size excels in near-field monitoring and tight spaces.
