8-Inch 2-Way Active Studio Monitors With EBM Waveguide With a smooth accurate frequency response; powerful amplification with tons of headroom; and Acoustic Tuning functions that ensure you get the best sound it s no wonder that Eris®-series studio monitors have been a runaway hit since their introduction. Building on the reputation of its award-winning predecessors the Eris 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. Designed for superior performance in both home studios and professional mix rooms the Eris Studio 8 features a custom-designed EBM (Elliptical Boundary Modeled) waveguide that provides superior high-frequency response and wide 120-degree horizontal dispersion to create a broader sweet spot. Narrow vertical dispersion reduces reflections from your desk and a 1.25-inch silk-dome tweeter ensures snappy accurate transient reproduction. An elegant new enclosure design improves the waveguide performance so you ll hear the finest details in your mix. The woven-composite 8-inch low-frequency driver offers Eris signature tight clear bass with plenty of punch. Its 140W of biamped power make the Eris Studio 8 more efficient than previous designs. The ported enclosure maximizes bass response and allows the Eris Studio 8 to reach down to an astonishing 35 Hz - with no 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 your Eris speakers up to virtually anything. Set Up Your Studio Monitors For Your Room. Eris® Studio 8 active monitors are equipped with Acoustic Tuning controls to ensure the flattest response in your mix environment.
