PreSonus Eris Studio 8 8-inch Powered Studio Monitor (Open Box)

The PreSonus Eris Studio 8 is an 8-inch powered studio monitor designed for accurate audio reproduction in home studios and professional mixing environments. These active speakers combine a custom-designed elliptical boundary modelled waveguide with a woven composite low-frequency driver to deliver detailed sound with controlled dispersion. The system provides 140 watts of bi-amped power through a class AB amplifier configuration, enabling the monitors to reproduce frequencies down to 35Hz despite their relatively compact dimensions. Key features include comprehensive acoustic tuning controls that allow users to adjust the speaker's response to their specific room environment. The front panel provides continuously variable controls for high frequency (±6 dB at 10 kHz), mid frequency (±6 dB at 1 kHz), and three-position acoustic space tuning to compensate for boundary effects when placed near walls. The 1.25-inch silk-dome tweeter works in conjunction with the proprietary waveguide to create a wide 120-degree horizontal dispersion pattern while minimizing vertical reflections from desk surfaces. Connectivity options include balanced XLR and ¼" TRS inputs alongside unbalanced RCA connections, making the monitors compatible with a wide range of audio interfaces, mixers, and playback devices. The Eris Studio 8 monitors are particularly well-suited for music producers, recording engineers, and content creators who require accurate monitoring in smaller spaces. Their combination of detailed high-frequency reproduction, substantial low-end extension, and flexible room correction makes them practical for critical listening applications where translation to other playback systems is essential. The vinyl-laminated medium-density fibreboard cabinet construction provides both acoustic stability and durability for long-term studio use.
