Open Box PreSonus Eris Studio 8 Studio Monitor (2nd Gen) (Each) Level 1

The PreSonus Eris Studio 8 active reference monitor is a 2-way system consisting of an 8" woven-composite woofer and a 1.25" silk-dome high-frequency driver. Noted for its detail and transparency, the Studio 8 speaker brings superior sound quality to home and project studios. This offers producers and engineers the fidelity they need to make informed mixing and mastering decisions for music that sounds great on any playback system—most importantly, ensuring it translates to consumer devices. The second-generation Eris Studio 8 contains substantial updates to its predecessor, improving both low- and high-end frequency response for even greater accuracy from the already award-winning PreSonus speaker formula. With an ideal combination of physical size, low-end extension and total volume output, Eris Studio 8 monitors are an exceptional reference speaker for medium-size tracking and mixing rooms.

Accurate and Reliable Monitoring

The Studio 8 speaker pushes 140 bi-amped watts—a notable boost in efficiency over the previous generation’s design, which supports crystal-clear sound reproduction with a maximum level of 106dB SPL. An 8" driver and front-firing bass port help generate punchy lows down to an impressive 35Hz (without a subwoofer), while an ultralow-mass tweeter takes over at 3.5kHz and carries the rest of the spectrum up to 20kHz. PreSonus Eris Studio 8 monitors provide rich lows and controlled highs for organic, uncolored playback that’s both accurate and reliable. Whether the Studio 8 is your primary or secondary set of monitors, its trustworthiness is a pivotal step toward better mix decisions that are never lost in translation.

Elliptical Boundary Modeled (EBM) Waveguide

Eris Studio 8 monitors have a custom-designed waveguide surrounding the high-frequency driver to give it an ultrawide horizontal dispersion measurement of 120°. For listeners, this means a much broader sweet spot than you’d get without EBM technology, as well as a more pronounced stereo image that’s immersive in its scope. Meanwhile, narrow vertical dispersion (60°) prevents desktop reflections from smearing the frequencies you’re hearing, so audio is always as crisp as can be. On their own, the Eris Studio 8 silk-dome tweeters are snappy and responsive, capable of reproducing transients with absolute precision. Paired with the PreSonus EBM waveguide, their performance is naturally enhanced for even more width and detail.
