Presonus Eris Studio 8 Active Monitor

The Presonus Eris Studio 8 is an 8-inch active studio monitor designed for accurate mixing in home studios and small professional rooms. It features a woven-composite low-frequency driver and a 1.25-inch silk-dome tweeter powered by 140-watt Class AB bi-amplification. Acoustic tuning controls allow adjustment for the flattest response in your environment.

Suited for Nearfield Mixing Without Subwoofer

This monitor reaches 35 Hz low-end extension through its ported enclosure, removing the need for a separate subwoofer in many setups. The custom EBM waveguide provides 120-degree horizontal dispersion for a wide sweet spot. Buyers needing higher maximum output than 106 dB SPL or a smaller footprint for desktop use should consider other options.

Simple Powered Setup With Room Calibration

Installation requires only mains power and a line-level signal from an audio interface or mixer via balanced XLR, TRS or unbalanced RCA inputs. Rear-panel acoustic tuning switches compensate for boundary placement and room anomalies. The main issues are insufficient gain staging causing noise floor rise or incorrect boundary settings producing bass buildup.
