The Quake 8 steel frame drivers are built for DIY cabinet builders and sound engineers replacing worn woofers in existing PA systems. These pro audio drivers deliver reliable mid-bass performance for live sound applications where durability and consistent output matter.

Each 8-inch driver handles 100 watts RMS (200 watts peak) with 94 dB sensitivity, providing solid volume levels without requiring massive amplifier power. The 55-5000 Hz frequency response covers fundamental frequencies for vocals and instruments, making these drivers suitable for main PA speakers or floor monitors.

The pressed steel chassis and 35-ounce magnet structure ensure long-term reliability under demanding live performance conditions. The 2-inch voice coil and 8-ohm impedance make these drivers compatible with most pro audio amplifiers and crossover networks. At 8 pounds each, these drivers provide substantial magnetic force while remaining manageable for cabinet construction.

Use these drivers for building custom PA cabinets for bands, replacing blown drivers in existing monitor wedges, or constructing practice room speakers for rehearsal spaces. They work well in venues accommodating 50-150 people when properly powered and paired with appropriate high-frequency drivers.

The drivers connect via standard speaker wire terminated with spade connectors or bare wire to binding posts. Each purchase includes a matched pair for stereo applications or dual-driver cabinet designs.

Seismic Audio backs these replacement drivers with a one-year warranty and ships them ready for immediate installation in your cabinet projects.

Frequently Asked Questions

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

When properly powered and housed in appropriate cabinets with tweeters, these drivers work well for venues up to 150 people. For larger spaces or outdoor events, you'll want to consider multiple cabinets or larger drivers. They're particularly effective for small club gigs, church services, or school auditoriums.

Do I need tweeters with these 8-inch drivers?

Yes, these drivers only cover frequencies up to 5000 Hz, so you'll need separate tweeters or horn drivers for crisp highs above that range. Most PA applications require crossover networks to properly split the signal between these woofers and high-frequency drivers for full-range sound reproduction.

What amplifier power do I need to drive these effectively?

These drivers handle 100 watts RMS each, so plan for amplifiers providing 75-150 watts per channel at 8 ohms. Running them at their full power rating gives you the most headroom, but they'll perform well with smaller amplifiers in lower-volume applications like practice rooms or small acoustic performances.

Can I replace blown drivers in my existing PA speakers with these?

These work as replacements if your current speakers use 8-inch drivers with similar mounting dimensions and 8-ohm impedance. Check that your existing cabinets can accommodate the mounting depth and that the frequency response matches your crossover design. The steel frame construction makes them suitable replacements for most generic PA speakers.

What tools do I need to install these drivers in cabinets?

You'll need a screwdriver for the mounting screws and wire strippers for connecting speaker wire to the terminals. The drivers mount from the front of the cabinet using standard wood screws through the mounting holes in the steel frame. No special mounting hardware is required beyond basic cabinet construction tools.
