PreSonus Eris Sub8 Compact Studio Subwoofer

The PreSonus Eris Sub8 Compact Studio Subwoofer is designed to work with any set of studio monitors, especially the PreSonus Eris E3.5 or E4.5 full-range studio monitors.

A 100W Class-AB amplifier powers the front-firing 8" paper-composite woofer, which offers a frequency response of 200 Hz down to 30 Hz with a respectable 113 dB peak SPL. The rear panel features a pair of 1/4" and RCA inputs as well as 1/4" and RCA thru/outputs. A variable input gain knob (-30 to +6 dB) and a continuously variable lowpass filter (50 to 130 Hz) helps you dial in the volume and low-frequency sweet spot. Additionally, a defeatable highpass filter removes frequency content below 80 Hz from the full-range signal sent from the Eris Sub8 output to the main speakers.

Other notable features include a polarity-invert switch and protection circuits for RF interference, output-current limiting, over-temperature, turn on/off transient, subsonic filter, and an external mains fuse.
