PreSonus Eris Studio 8 Active Studio Monitor

With lows down to 35 Hz and an elliptical waveguide for controlled highs with a wide sweet spot, the Studio 8 builds on the PreSonus Eris series' reputation.

Building on the reputation of its award-winning predecessors, the Eris(R) Studio 8 is a substantial update that delivers richer low-end and more controlled high-frequency response, reproducing every detail in your recordings with a natural sound unparalleled in its class.

Get a closer look at the Eris Studio Series in this video from PreSonus:

The custom-designed EBM (Elliptical Boundary Modeled) waveguide provides superior high-frequency response and wide 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. An elegant enclosure design improves the waveguide performance so you'll hear the finest details in your mix.

The woven-composite low-frequency driver offers Eris' signature tight, clear bass, with plenty of punch. The ported enclosure and 140W of biamped power maximizes bass response and allows the Eris Studio 8 to reach down to an astonishing 35 Hz -- without a subwoofer. Designed for superior performance in both home studios and professional mix rooms, the Eris Studio 8 combines flexible connectivity with sonic accuracy that puts it a class all its own.
