PreSonus Eris Pro Sub 10 — 10-inch Active, Front-Firing Studio Subwoofer

Intended for serious personal studios and professional music-production environments, the Eris Pro Sub 10 helps you take charge of the low-frequency foundation of your mix, complementing full-range monitors without overshadowing them and extending the reach of your full-range system’s low end with a more musical and natural approach.

• Big sub-low end. 10-inch, front-firing, glass-composite, low-frequency transducer.
• Front-firing, bass-reflex acoustic port.
• Continuously variable lowpass filter (50 Hz to 130 Hz) sets the upper frequency reproduced by the subwoofer.
• Switchable highpass filter removes frequency content below 80 Hz from the full-range subwoofer outputs to the main monitors.
• Momentary footswitch (included) bypasses the subwoofer, highpass filter, and Sub Out.
• Input gain control (-30 dB to +6 dB, continuously variable), polarity invert switch, and ground-lift switch.
• Power to spare: 170 watt (RMS), Class AB amplification for up to 113 dB SPL, with a frequency response of 20 to 200 Hz.
• Left and right, balanced XLR and ¼-inch TRS and unbalanced RCA main inputs.
• Left and right balanced XLR and ¼-inch TRS pass-through outputs and XLR subwoofer output for connecting a second Eris Pro Sub 10.
