The PreSonus Eris Studio 4 (2nd Gen) sets a new standard for compact studio monitors. With its surprising amount of low end and a wide, well-controlled sweet spot, you can enjoy studio-grade monitoring in even the smallest of spaces. The custom-designed EBM (Elliptical Boundary Modeled) waveguide provides a superior high-frequency response and wider 100-degree horizontal dispersion to create the aforementioned broad sweet spot. Narrow vertical dispersion reduces reflections from your desk and a silk-dome tweeter ensures snappy, accurate transient reproduction. The woven composite low-frequency driver offers Eris' signature tight, clear bass with plenty of punch. The ported enclosure maximizes bass response and allows the Eris Studio 4 to reach down to a highly respectable 55Hz—without a subwoofer.

Take charge of the low-frequency foundation of your mix with the Eris Pro Sub 10 (2nd Gen). The Eris Pro Sub 10 complements full-range monitors without overshadowing them and extends the reach of your full-range system's low end with a natural sound.

Powerful and musical, the PreSonus Eris Pro Sub 10 active, front-firing studio subwoofer is designed to deliver fast and accurate transient response, extending low frequencies down to 20Hz, allowing you to hear the full-spectrum range of your mix. Driven by 170W (RMS) Class-AB amplification, the Eris Pro Sub 10's 10", glass-composite, low-frequency driver delivers tight, responsive sub-bass, thanks to its lightweight and rigid cone.

Extensive user controls include a continuously variable lowpass filter for creating a seamless crossover transition between the full-range studio monitors and subwoofer for the most accurate listening environment possible. An onboard footswitch control lets you quickly A/B your mix with and without the subwoofer for easy referencing.
