The PreSonus Eris Pro Sub 10 is an active studio subwoofer designed to extend the low-frequency range of full-range monitors, giving you deep, accurate bass down to 20 Hz.

Its 10″ glass-composite low-frequency driver is front-firing in a bass-reflex cabinet, delivering tight, responsive sub-bass — ideal for music production, mixing, film audio, gaming, or any setup where you want the full low-end spectrum. 

With 170 W RMS Class-AB amplification and flexible crossover/phase controls, the Sub 10 integrates smoothly into 2.1 or larger monitoring systems, giving you control and clarity over the low frequencies without muddying the rest of the mix.

Whether you’re building a professional mixing setup, a home studio, or a high-fidelity media rig — the Eris Pro Sub 10 offers a robust low-end foundation that complements near-field monitors while preserving precision.
