Audibax DSP15s - 15" 500W active subwoofer with DSP and presets (Music, Live, DJ, Speech)

The Audibax DSP15s is a professional 15" active subwoofer that integrates a high-performance Class D amplifier and an internal DSP to adapt the system's response to each application. Through its playback modes ( Music, Live, DJ, Speech ) and three-band equalization, you can optimize the bass quickly and precisely. Its 18mm MDF enclosure with a black acrylic lacquer finish ensures robustness, while the balanced connections allow for seamless integration into live sound, DJ, and installed systems.

With a frequency range of 26–800 Hz , 500 W RMS power, and sound pressure levels up to 130 dB (peak) , the DSP15s delivers punch and control on dance floors, stages, and multipurpose rooms. It features balanced L/R XLR inputs , a Jack/XLR line input , and balanced XLR outputs , with selectable output modes for Full Range or High-Pass operation directly from the subwoofer, depending on the system configuration.

Frequently Asked Questions

What presets does the DSP include?
Music, Live, DJ and Speech modes, plus three-band equalization, to adjust the system's response according to usage.

Can I filter the satellite outputs?
Yes. From the panel you can select the Full Range or High-Pass output mode on the XLR outputs, making it easier to connect to higher-end speakers without external processing.

How does it differ from the DSP15s G2?
There is a G2 version with different specifications (e.g., power and frequency response). This datasheet corresponds to the DSP15s (500 W, 26–800 Hz) .

Integration Notes

• Use balanced XLR cabling to minimize noise and hum over long runs.
• Adjust the DSP preset to the music program and working volume to maximize punch and clarity.
• For arrangements with multiple subs, position them symmetrically and check the polarity to sum in phase.
