Step up your monitoring game with the PreSonus Eris Studio 8, the largest member of the Eris Studio line, delivering professional-grade sound with power and precision. Featuring an 8-inch woven composite woofer paired with a 1.25-inch silk-dome tweeter in a revolutionary EBM (Elliptical Boundary Modeled) waveguide, the Eris Studio 8 provides extended low-end response, silky smooth highs, and an exceptionally wide sweet spot for accurate stereo imaging. Its front-ported enclosure produces tight, controlled bass, while reducing smearing and distortion, making it perfect for modern production that demands clarity in the low frequencies. With 140 watts of Class AB bi-amplification, the Eris Studio 8 reaches up to 106 dB of maximum continuous output — more than enough power for project and professional studios alike. The built-in acoustic tuning controls, including mid- and high-frequency trims plus acoustic space compensation, let you adapt the monitor’s response to your specific room setup, whether in a corner, near a wall, or in an open mixing environment.
