Audibax DSP12s - 12" Active Subwoofer (400 W RMS) with DSP and Class D Amplifier

Audibax DSP12s - 12" Active Subwoofer (400 W RMS) with DSP and Class D Amplifier

The Audibax DSP12s is a professional 12-inch active subwoofer that integrates a 400W RMS Class D amplifier and DSP processing to tailor its response to each application. Its design combines an 18mm MDF enclosure with a black acrylic lacquer finish and a 12" woofer with a 60oz magnet and 75mm voice coil, achieving powerful and controlled performance from 26Hz to 800Hz . The rear panel offers balanced XLR/Jack inputs and outputs, XLR signal pass-through, and Speakon connectors for easy integration into racks and modular systems. With a continuous SPL of 123dB and a peak SPL of 128dB , the DSP12s provides ample punch and headroom for rental, mobile DJs, venues, and PA reinforcement.

The internal DSP allows you to select preset modes (Music, Club/Live, DJ, Speech/Voice), adjust the phase (0°/180°) , and switch between Full Range and High-Pass , optimizing crossover with satellites and system intelligibility. Its universal 110–240 V power supply , compact dimensions ( 480 × 380 × 510 mm ), and weight of 22.5 kg facilitate daily transport and setup.

Frequently Asked Questions

• Can I use it with any satellite speaker? Yes, thanks to the Full Range/High-Pass switch and the balanced L/R output, it integrates with most active satellites; adjust the crossover and phase for the best summation.
• What do the DSP presets do? They adapt the equalization and dynamics to different uses: Music/Club for powerful bass, DJ for more punch, and Voice/Speech to prioritize clarity.
• Does it have phase control? Yes, a 0°/180° selector to align the sub with the satellites according to their location.
• How do I daisy-chain multiple units? Use the XLR L/R (thru) outputs to pass the signal to the next sub or to the tops, keeping the wiring balanced.

Good installation practices

• Location: Place the sub on the floor and close to walls for efficiency; avoid immediate obstructions to the port/speaker.
• Alignment: Try 0°/180° phase and High-Pass switching to maximize summation with the tops.
• Gain and protection: adjust the level to prevent the Limit indicator from lighting up continuously.
• Power supply: Use stable lines and grounding; do not share overloaded power strips with high-load equipment.

Notes and compatibility

This model corresponds to the DSP12s (400 W RMS) . A DSP12s G2 version exists with different specifications (e.g., power and dimensions); please verify the exact version when planning your system.
