The Shockwave-12 pair delivers serious low-end punch for DJs, bands, and venues that need deep bass without massive cabinets. These powered 12" subwoofers handle medium-sized clubs, bars, and outdoor events up to 300 people with authority.

Each cabinet pushes 400 watts RMS through a custom 12" woofer with 2.5" voice coil, extending your system's frequency response down to 40 Hz. The built-in Class D amplifier delivers 800 watts peak power while staying cool with active fan protection.

The 93 dB sensitivity and 121 dB max SPL mean these subs cut through without strain, while the variable low-pass filter (40-250 Hz) lets you dial in the perfect crossover point for your mains. At 50.7 pounds each, they're portable enough for mobile setups but built with 5/8" plywood and MDF construction for durability. The 100 Hz high-pass outputs let you daisy-chain to your powered mains, cleaning up their low end while the subs handle the foundation.

Connect via XLR inputs and outputs for clean signal chain integration. Each cabinet includes pole mount hardware for elevated main speakers. Recessed handles and metal corner protection handle the rigors of regular transport.

Seismic Audio backs each pair with a one-year warranty and ships from our warehouse. Professional-grade bass reproduction at a price point that makes sense for working musicians and mobile entertainers.

Frequently Asked Questions

What size venue can the Shockwave-12 pair handle?

These subwoofers work well for indoor venues up to 300 people or outdoor events up to 200 people, depending on music style and crowd expectations. They're ideal for clubs, bars, wedding receptions, and small to medium concert venues. For larger spaces, consider adding a second pair or moving up to 15" subwoofers.

What cables do I need to connect these subwoofers?

You'll need XLR cables to connect from your mixer to the first subwoofer, then XLR cables from the subwoofer outputs to your main speakers. The high-pass outputs clean up your mains by removing low frequencies below 100 Hz. Standard XLR microphone cables work fine for these connections.

Do I really need subwoofers if I have full-range speakers?

Yes, subwoofers make a significant difference even with full-range mains. They handle the demanding low frequencies that stress smaller drivers, letting your main speakers focus on mids and highs where they perform best. The result is cleaner overall sound, more headroom, and better bass extension than mains alone can provide.

How do I set the crossover frequency on these subs?

The variable low-pass filter knob lets you adjust the crossover point from 40-250 Hz to match your main speakers. Start around 80-100 Hz for most full-range speakers, then adjust by ear. The goal is seamless blending where you can't tell where the subwoofer stops and the mains begin.

Can I use just one Shockwave-12 instead of buying the pair?

While one subwoofer will add low end to your system, the pair provides better coverage and power distribution across your venue. Bass frequencies are omnidirectional, but having two subs reduces dead spots and provides redundancy. For smaller gigs, one might work, but the pair gives you the full impact these cabinets were designed to deliver.
