PreSonus Eris Studio 8" Active Studio Monitor

The PreSonus Eris Studio 8 is a biamplified nearfield studio monitor built around an 8-inch woven-composite woofer and a 1.25-inch silk-dome tweeter, delivering a frequency response from 35 Hz to 20 kHz. The custom-tuned EBM waveguide provides 120-degree horizontal by 60-degree vertical dispersion, creating a wide and consistent sweet spot that benefits collaborative mixing sessions and reduces the need for precise head positioning. With 140 watts of Class AB amplification split between the high and low-frequency drivers, the Eris Studio 8 produces a peak SPL of 105 dB at one meter — more than enough output for nearfield monitoring in small to mid-sized control rooms.

Where this monitor distinguishes itself from competitors in its price range is the depth of its acoustic tuning controls. The rear panel features a highpass filter for integrating with a subwoofer, HF and midrange adjustment knobs for tailoring the tonal balance to your room and preferences, and a three-position Acoustic Space switch that reduces low-frequency output when the monitor must be placed near walls or in corners. Input options include balanced XLR, balanced 1/4-inch TRS, and unbalanced RCA, covering connections from professional audio interfaces to consumer playback devices. Built-in protection circuitry — including RF shielding, current limiting, over-temperature shutdown, and a soft-start power-on sequence — safeguards both the amplifier and drivers during extended sessions, adding confidence that these monitors will deliver reliable performance over the long term.
