The Shockwave-15 delivers professional-grade low-end for DJs, bands, churches, and venues that need serious bass extension without breaking the budget. This powered 15" subwoofer handles the foundation frequencies that separate amateur sound from professional live sound reinforcement.

Built around a heavy-duty 15" woofer with 70 oz magnet and 3" voice coil, the Shockwave-15 reproduces frequencies down to 40 Hz with authority. The integrated 500-watt RMS Class D amplifier (1000 watts peak) provides clean, efficient power with built-in protection circuits and fan cooling to maintain performance during extended use.

Key features include variable low-pass filtering from 40-250 Hz, allowing precise integration with your main speakers, plus a 100 Hz high-pass output for daisy-chaining full-range cabinets without bass overlap. The cabinet delivers 123 dB maximum SPL with 93 dB sensitivity, ensuring it cuts through mix without requiring excessive drive levels.

This subwoofer excels in clubs, bars, churches, wedding receptions, and outdoor events for crowds up to 300 people. The compact 23" x 19" x 21" cabinet fits easily in vehicles and tight stage areas while the ported design maximizes low-frequency output. Dual XLR inputs and outputs simplify system integration whether you're running stereo or mono configurations.

Setup requires standard XLR cables to connect from your mixer or powered speakers. The included pole mount accommodates standard speaker stands, and recessed handles ease transport. Backed by Seismic Audio's one-year warranty with fast shipping nationwide.

Frequently Asked Questions

What size venue can the Shockwave-15 handle?

The Shockwave-15 effectively covers venues up to 300 people, including clubs, wedding receptions, outdoor events, and medium-sized performance spaces. The 123 dB maximum SPL and efficient Class D amplifier provide sufficient bass reinforcement for dance floors and live music without requiring multiple subwoofers. For larger venues over 300 capacity, consider pairing two units or upgrading to an 18" model.

What cables do I need to connect the Shockwave-15?

You'll need standard XLR cables to connect the subwoofer to your mixer or powered speakers. The dual XLR inputs accept either mono or stereo signals, and the XLR outputs allow daisy-chaining to additional speakers. The high-pass output feature eliminates low frequencies to connected full-range speakers, preventing bass overlap and improving system clarity.

How does the Shockwave-15 compare to using full-range speakers alone?

Adding the Shockwave-15 extends your system's frequency response down to 40 Hz, well below what most full-range PA speakers can reproduce effectively. This dedicated subwoofer handles bass-heavy music genres, kick drums, and bass guitars with authority that full-range speakers simply cannot match. The variable crossover and high-pass outputs ensure seamless integration without muddy overlap frequencies.

Can I use multiple Shockwave-15 subwoofers together?

Yes, you can daisy-chain multiple Shockwave-15 units using the XLR outputs to create a larger bass array. For stereo applications, connect one subwoofer to each channel of your mixer. Multiple subwoofers increase overall SPL capability and provide more even bass coverage across larger venues, making this an effective scaling solution for growing sound systems.

What's the difference between the low-pass filter and crossover settings?

The variable low-pass filter (40-250 Hz) controls which frequencies the subwoofer reproduces, allowing you to dial in the perfect blend with your main speakers. The 150 Hz internal crossover point is fixed and optimized for the 15" driver. The 100 Hz high-pass output sends filtered signal to connected full-range speakers, removing bass frequencies they don't need to reproduce for cleaner overall sound.
