PreSonus Eris Studio 8

The Eris Studio 8 is a professional-grade active studio monitor engineered for accurate, flat-response mixing and mastering. Its substantial yet balanced construction sits comfortably in mid-field monitoring setups, delivering the detail and clarity needed for critical listening without fatigue. Built for engineers and producers who demand transparent, dependable sound in the studio.

Design & Build Quality

The cabinet features internally braced MDF construction with black vinyl veneer, weighing just over 10kg at a height of 419mm. Rounded cabinet edges and a front-exiting reflex port minimize diffraction artifacts, contributing to cleaner frequency response and more accurate stereo imaging across the listening field.

Audio Performance & Control

A 140-watt bi-amped configuration — 75W for lows and 65W for highs crossing at 3.5kHz — delivers extended dynamic range with a frequency response of 35Hz–20kHz and peak output of 106dB SPL at one meter. Comprehensive on-board controls include a 12dB/octave low-cut filter (selectable at 80Hz or 100Hz), an acoustic space adjustment offering 2dB or 4dB shelving below 800Hz, and two parametric EQ bands providing ±6dB adjustment at 1kHz and 10kHz, allowing precise tailoring to room acoustics and personal preference.
