The Baby Tremor 15 delivers the deep bass foundation that DJs, bands, and venues need when main speakers alone can't handle the low end. This passive subwoofer pair extends your PA system's frequency response down to 35 Hz, adding the punch that makes music feel full and impactful.

Each 15-inch subwoofer handles 300 watts RMS (600 watts peak) with 96 dB sensitivity, providing substantial output for medium-sized venues. The ported enclosure design maximizes bass response while the 70-ounce magnet and 3-inch voice coil deliver controlled, tight low frequencies that cut through without muddiness.

Built with 5/8-inch plywood construction and black carpet covering, these subs handle the rigors of mobile performance while maintaining clean aesthetics. Recessed metal handles and protective corners make transport manageable despite the 58-pound weight per cabinet. The 8-ohm impedance works with most power amplifiers and can be daisy-chained for larger installations.

Perfect for DJ setups in clubs or wedding venues up to 300 people, live bands needing bass reinforcement, or permanent installations in churches and community centers. The dual 1/4-inch and dual Speakon connectors provide flexible connection options for professional amplifiers.

Connect directly to your power amplifier using speaker cables (sold separately) or daisy-chain multiple units for expanded coverage. Each pair includes two complete subwoofer cabinets ready for immediate use.

Backed by Seismic Audio's one-year warranty with direct manufacturer support and fast shipping to get your system running quickly.

Frequently Asked Questions

What size venue can these subwoofers handle?

The Baby Tremor 15 pair works well for venues up to 300 people, including wedding receptions, small clubs, church sanctuaries, and outdoor gatherings. For larger venues or outdoor festivals, consider adding more subwoofers or stepping up to our 18-inch models. The 300 watts RMS per cabinet provides sufficient headroom for most DJ and live band applications in medium-sized spaces.

What cables and amplifier do I need with these passive subwoofers?

You'll need a dedicated power amplifier and speaker cables to run these passive subs. Use Speakon or 1/4-inch speaker cables (not instrument cables) rated for your amplifier's output. A stereo amplifier delivering 300-600 watts per channel at 8 ohms works well, or you can bridge a larger amp for more power. The dual connectors on each cabinet allow daisy-chaining to additional subwoofers.

Can I use these subwoofers with my existing PA speakers?

Yes, these subs are designed to extend the low-end response of full-range PA speakers. You'll typically run your main speakers full-range and add these subs for frequencies below 80-100 Hz. Many powered mixers have dedicated subwoofer outputs with built-in crossovers, or you can use an external crossover to split the signal appropriately between your mains and subs.

How do these compare to powered subwoofers?

Passive subwoofers like the Baby Tremor 15 offer more flexibility in amplifier choice and are often more reliable since there's no built-in amp to fail. However, you need to provide external amplification and potentially a crossover. Powered subs are more convenient for plug-and-play setups but limit you to the manufacturer's amplifier choice and add more potential failure points.

Do these subwoofers work for both DJ and live band applications?

Absolutely. The 35 Hz - 800 Hz frequency response handles both electronic music's deep bass and live instruments like kick drums and bass guitars. The ported design provides the extended low-end response DJs need for hip-hop and EDM, while the controlled output works well for live bands without overwhelming vocal frequencies. The 96 dB sensitivity ensures efficient performance with most professional amplifiers.
