The Presonus Eris® Studio 8 is a professional 8-inch, 2-way active studio monitor built for home studios and professional mixing rooms.
Featuring the next-generation EBM (Elliptical Boundary Modeled) waveguide, it offers 120° horizontal and 60° vertical dispersion for a broad sweet spot and minimized desk reflections.
The 8-inch woven composite woofer delivers tight, punchy bass, while the 1.25-inch ultra-light silk-dome tweeter ensures crisp and accurate high frequencies.
Powered by 140 watts of Class AB biamplification, the Eris Studio 8 delivers a clean, detailed response with excellent headroom.
Its 35Hz–20kHz frequency range allows deep low-end reproduction without a subwoofer.
With a front-firing acoustic port for enhanced bass and optimized internal bracing, resonance is minimized for transparent sound.
Balanced XLR and TRS inputs and an unbalanced RCA input make it compatible with nearly any audio interface or mixer.
Fine-tune your sound with HF, Mid, Acoustic Space, and High-Pass Filter controls to match any room.
