PreSonus has introduced the Eris Sub8 subwoofer, designed to add sub-lows to any set of small monitor speakers. It was especially designed to complement the voicing and frequency response of Eris-series media reference monitors.
Driven by an onboard 100 watt Class A/B amplifier, the Eris Sub8 delivers low end all the way down to 30 Hz—a full 50Hz below the Eris E3.5s.
It naturally extends the reach of Eris E3.5 or E4.5 monitors in a manner appropriate to smaller rooms.
Eris Sub8 can connect to full-range monitors via ¼” TRS or RCA, with an input level control and a polarity invert switch.
Its high pass filter switch and variable low pass filter/crossover control ensure the subwoofer starts working at the precise low-frequency point where some full-range monitors drop off.
