The PreSonus Eris Studio 4 sets a new standard for compact studio monitors. With its surprising amount of low-end and wide, well-controlled sweet spot, you can enjoy premium, accurate monitoring in even the smallest of mixing spaces.
Flexible Connectivity
The Eris Studio 4 drives up to 99 dB of crystal-clear, transparent sound with its 4.5-inch woven composite low-frequency driver and 1-inch silk-dome tweeter, powered by 50-watt Class AB bi-amplification. The ported enclosure creates a deep, tight low-end, while an EBM waveguide provides a wide, controlled sweet spot and detailed high-frequency reproduction. Designed for superior performance in home studios and small professional mix rooms, the Eris Studio 4 combines flexible connectivity with sonic accuracy that puts it in a class all its own.
Elegant Design
The custom-designed EBM (Elliptical Boundary Modeled) waveguide provides a superior high-frequency response that allows you to hear the finest details in your mix, while a wide 120-degree horizontal dispersion creates a broad sweet spot with lifelike stereo imaging. Narrow vertical dispersion reduces reflections from your desk, and a silk-dome tweeter ensures snappy, accurate transient reproduction.
Flexible Connectivity
The 4.5-inch, woven-composite, low-frequency driver produces tight, clear bass with plenty of punch that defies the Eris Studio 4's space-saving size. The ported enclosure and 50W of bi-amped power combine to maximize bass response and allow the Eris Studio 4 to reach down to an astonishing 55 Hz. Designed for superior performance in both home studio and small professional mix rooms, the Eris Studio 4 combines flexible connectivity with sonic accuracy that puts it in a class all its own.
