PreSonus Eris Studio 4 4" Active Studio Monitor w/ EBM Waveguide

The Eris® Studio 4 sets a new standard for compact studio monitors. With its surprising amount of low-end and a wide, well-controlled sweet spot, you can enjoy premium, accurate monitoring in even the smallest of mixing spaces. Designed for superior performance in both home studios and small professional mix rooms, the Eris Studio 4 combines flexible connectivity with sonic accuracy that puts it a class all its own.

The custom-designed EBM (Elliptical Boundary Modeled) waveguide provides superior high-frequency response that allows you to hear the finest details in your mix, while a wide 100-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.

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 biamped power combine to maximize bass response and allow the Eris Studio 4 to reach down to an astonishing 55 Hz — without a subwoofer!

Flexible input options let you connect almost any line-level source, from mixers to audio interfaces and more. You'll have no problem hooking Eris speakers up to virtually anything.
