Presonus Eris Studio 8

The PreSonus Eris Studio 8 is a premium active studio monitor designed for audio engineers, producers, and musicians who demand high-precision audio and a broad stereo image. Thanks to the custom-designed EBM (Elliptical Boundary Modeled) waveguide, the monitor delivers an expansive sweet spot, making it ideal for both home studios and professional mix rooms.

With 140W Class-AB amplification, the 8-inch woven composite woofer and 1.25-inch silk dome tweeter provide an extended frequency response from 35 Hz to 20 kHz and a powerful output of 105 dB SPL. The rear panel features comprehensive acoustic tuning controls, including high and mid-frequency adjustments, a low-cut filter for subwoofer integration, and a three-position Acoustic Space switch to address boundary reflections.
