10-Inch, Active, Front-Firing Studio Subwoofer Intended for serious personal studios and professional music-production environments, the Eris® Pro Sub 10 helps you take charge of the low-frequency foundation of your mix. An ideal companion to Eris Pro- and Eris Studio-series reference monitors, 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 20 Hz, 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-inch, glass-composite, low-frequency driver delivers tight, responsive sub-bass, thanks to its lightweight and rigid cone. This design provides lower distortion than other materials for sub-bass reproduction that's as coherent and clear as your full-range monitors.

Extensive user controls include input gain, continuously variable lowpass filter for creating a seamless crossover transition, and a switchable highpass filter that removes content below 80 Hz from the full-range signal sent to the monitors. A continuously variable lowpass filter (50 Hz to 130 Hz) allows you to create a seamless crossover transition between the full-range studio monitors and subwoofer for the most accurate listening environment possible.

Eris® Pro Sub 10 subwoofers provide the connections needed to act as the central hub for a basic monitoring setup, including left and right balanced XLR and ¼-inch TRS and unbalanced RCA main inputs. Connect full-range monitors with left and right balanced XLR or ¼-inch TRS outputs. An XLR subwoofer output lets you connect a second Pro Sub 10.

Seamless System Integration.

The Eris® Pro Sub 10 integrates seamlessly with your full-range monitors. A variable lowpass filter sets the upper (crossover) frequency reproduced by the subwoofer. A switchable highpass filter on the full-range outputs helps avoid frequency cancellation and reinforcement in the subwoofer’s upper range, while a polarity-invert function ensures your system is in phase. A momentary footswitch (included) makes it easy to compare your mix with or without sub-bass frequencies.
