The Shockwave-12 is a powered 12" subwoofer designed for DJs, bands, and live sound engineers who need serious low-end reinforcement for medium-sized venues. This compact sub delivers professional bass response that far exceeds what you'd expect from its footprint.

Built around a 12" woofer with a 60 oz magnet and 2.5" voice coil, the Shockwave-12 produces deep, punchy bass from 40 Hz to 200 Hz. The built-in Class D amplifier delivers 400 watts RMS and 800 watts peak power, pushing maximum SPL to 121 dB while maintaining less than 0.1% total harmonic distortion.

The adjustable low-pass filter ranges from 40 Hz to 250 Hz, letting you dial in the perfect crossover point for your main speakers. A 100 Hz high-pass output feeds your full-range speakers while filtering out the low frequencies that the subwoofer handles, preventing overlap and improving system clarity.

Perfect for clubs, bars, wedding receptions, and outdoor events serving 100-300 people, the Shockwave-12 pairs well with 12" or 15" main speakers. The ported cabinet design maximizes output while keeping weight to 50.7 pounds for easy transport.

Dual XLR inputs and outputs provide flexible connectivity with your mixer or powered speakers. The included pole mount lets you position main speakers on top for a compact, integrated PA system.

Seismic Audio backs the Shockwave-12 with a one-year warranty and fast shipping, delivering professional-grade bass performance at a price that works for working musicians.

Frequently Asked Questions

What size venue can the Shockwave-12 handle?

The Shockwave-12 is designed for medium-sized venues serving 100-300 people, including clubs, bars, wedding receptions, and outdoor events. Its 121 dB maximum output and 40 Hz low-frequency extension provide solid bass reinforcement for dance floors and live music without overwhelming smaller spaces. For larger venues over 300 people, consider pairing multiple units or stepping up to the 15" model.

What cables do I need to connect the Shockwave-12?

You'll need XLR cables to connect the subwoofer. Run an XLR from your mixer's subwoofer output (or main output) to the Shockwave-12's input, then use another XLR cable from the sub's high-pass output to your main speakers. This daisy-chain setup filters low frequencies from your mains while sending full-range signal to the subwoofer.

Do I need a subwoofer with 12" or 15" main speakers?

Yes, adding the Shockwave-12 significantly improves your system's low-end response and overall headroom. Most 12" and 15" full-range speakers start rolling off around 50-60 Hz, while the Shockwave-12 reaches down to 40 Hz. This gives you the deep bass needed for electronic music, hip-hop, and modern rock, while letting your main speakers focus on mids and highs where they perform best.

Can I adjust the crossover frequency on this subwoofer?

The Shockwave-12 has a fixed 150 Hz crossover point for its internal filtering, but features an adjustable low-pass filter from 40-250 Hz that controls how much of the frequency spectrum the subwoofer reproduces. The high-pass output to your main speakers is fixed at 100 Hz, which works well with most full-range PA speakers by removing low frequencies that can cause distortion and reduce clarity.

How does the Shockwave-12 compare to passive subwoofers?

The powered Shockwave-12 includes a built-in 400-watt RMS Class D amplifier, eliminating the need for a separate subwoofer amplifier and reducing your gear load. The integrated amp is perfectly matched to the driver, includes protection circuits, and provides level control and signal processing. This makes setup faster and more reliable than passive subs that require external amplification and additional cables.
