Manufacturer's Description

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 studio-grade monitoring in even the smallest of spaces.

The custom-designed EBM (Elliptical Boundary Modeled) waveguide provides superior high-frequency response and wider 100-degree horizontal dispersion to create a broad sweet spot. Narrow vertical dispersion reduces reflections from your desk and a silk-dome tweeter ensures snappy, accurate transient reproduction.

The woven composite low-frequency driver offers Eris’ signature tight, clear bass with plenty of punch. The ported enclosure maximizes bass response and allows the Eris Studio 4 to reach down to a highly respectable 55 Hz – without a subwoofer!
