PreSonus Eris Sub 8 8-inch Powered Studio Subwoofer

A Top-notch Studio Sub with Impressive Features
The PreSonus Eris Sub8 offers clean low-end reinforcement for your monitoring chain, thanks to a first-rate low-frequency driver and a state-of-the-art 100-watt Class AB amplifier. Continuously variable input gain and lowpass filter controls make tailoring this powered studio subwoofer to your room easy, while a defeatable highpass filter prevents sub-80Hz frequency content from reaching your main monitors. Easily connect it to the rest of your gear with a full complement of balanced and unbalanced I/O. You also get a polarity invert feature, plus solid protection against RF interference, extreme output current, excessive heat, and more. The bottom line: the PreSonus Eris Sub8 is a top-notch studio subwoofer that’s a must-have add-on for your Eris E3.5, E4.5, or other small-sized studio monitors.



First-rate driver and state-of-the-art amplifier
The Eris Sub8 delivers smooth low-frequency transients, thanks to its first-rate driver and state-of-the-art amplifier. The 8-inch, front-firing, paper-composite transducer includes a high-elasticity rubber surround for squeaky-clean low-frequency audio reproduction, while the 100-watt Class AB amplifier supplies robust output with minimal distortion. We’re impressed by the Eris Sub8’s performance here at Sweetwater — for the money, it’s an excellent powered studio subwoofer.






Customizable sound reproduction for any room
Tailoring the PreSonus Eris Sub8 to your room is a piece of cake, by virtue of its plentiful tuning controls. A gain knob enables -30dB to +6dB of continuously variable output, while a continuously variable lowpass filter cleans up unwanted resonances in the 50–130Hz frequency range. You also get a defeatable highpass filter that removes the sub-80Hz frequency content from the Eris Sub8’s full-range output before it reaches your main studio monitors. A polarity invert switch rounds out the Eris Sub8’s robust feature set.
