The Mini-Tremor powered 12" subwoofer brings serious low-end impact to compact live sound and DJ setups where space matters but bass can't be compromised. This active subwoofer delivers the deep foundation your PA system needs without overwhelming smaller venues or transport budgets.

Powered by a 350-watt RMS Class D amplifier pushing 700 watts peak, the Mini-Tremor drives its 12" woofer with a 2" voice coil and 50-oz magnet to produce clean, controlled bass down to 45 Hz. The built-in low-pass filter adjusts from 40-150 Hz, letting you dial in the perfect crossover point for your main speakers.

The ported cabinet design maximizes output while the 95 dB sensitivity rating ensures efficient power transfer. At 8 ohms impedance, it pairs well with most PA systems. The 5/8" plywood front panel and MDF construction provide the rigid enclosure needed for tight, punchy bass response.

Perfect for coffee house gigs, small wedding receptions, DJ sets in clubs up to 150 people, or as additional low-end support for larger systems. The compact 18.5" x 15.75" x 15.75" footprint and 43-pound weight make it easy to transport and position.

Connect via XLR combo inputs with XLR male outputs for daisy-chaining. The recessed pocket handles and pole mount compatibility add practical setup options.

Backed by Seismic Audio's one-year warranty and fast shipping. Professional-grade bass performance engineered for working musicians and mobile DJs.

Frequently Asked Questions

What size venue can the Mini-Tremor handle?

The Mini-Tremor works well for intimate venues up to 150 people, including coffee houses, small wedding receptions, acoustic performances, and DJ sets in smaller clubs. Its 700-watt peak output and efficient 12" driver provide enough low-end impact for these spaces without overwhelming the room. For larger venues, consider pairing two Mini-Tremors or stepping up to the 15" or 18" Tremor models.

What cables do I need to connect the Mini-Tremor to my mixer?

You'll need a standard XLR cable to connect from your mixer's subwoofer output or aux send to the Mini-Tremor's XLR combo input. The subwoofer includes male XLR outputs, so you can daisy-chain signal to your main speakers using another XLR cable. This eliminates the need for a separate crossover since the Mini-Tremor handles the low-pass filtering internally.

How do I set the crossover frequency on the Mini-Tremor?

The Mini-Tremor features a variable low-pass filter that adjusts from 40 Hz to 150 Hz, controlled by a knob on the rear panel. Start around 80-100 Hz for most full-range speakers, then adjust by ear to eliminate overlap and achieve smooth integration. Higher settings work better with smaller main speakers that roll off earlier, while lower settings suit larger mains with extended bass response.

Do I need a subwoofer if I already have 12" or 15" main speakers?

Even with 12" or 15" main speakers, a dedicated subwoofer like the Mini-Tremor adds focused low-end impact and takes bass duty off your mains. This improves overall clarity since your main speakers can focus on mids and highs while the subwoofer handles frequencies below 100 Hz. The result is tighter, more controlled bass and cleaner vocal reproduction from your main PA speakers.

How does the Mini-Tremor compare to passive subwoofers?

As an active subwoofer, the Mini-Tremor includes its own 350-watt RMS amplifier perfectly matched to the 12" driver, eliminating guesswork about power requirements. You also get built-in crossover control and signal processing that would require separate rack gear with passive subs. This makes setup simpler and often more cost-effective than buying a passive sub plus the amplifier and crossover needed to drive it properly.
