Overview
Expand the frequency range of your music production studio with thePreSonus Eris Sub 8BT, a front-firing 8″ active subwoofer that’s designed to complement full-range monitors like the Eris Studio 3.5 or Studio 5. Adding a subwoofer to your monitor setup enables you to hear the low-frequency foundation of your mix more accurately, allowing you to make better-informed decisions and create more translatable mixes.
The Eris Sub 8BT utilizes a 50W RMS Class-AB amplifier to power the 8″ composite woofer, which offers a frequency response of 30 to 200 Hz and a max SPL of 103 dB. The rear panel has a comprehensive set of controls to fine-tune the subwoofer’s performance including input gain, continuously variable low-pass filter for creating a seamless crossover transition, and a switchable high-pass filter that removes content below 80 Hz from the full-range signal sent to the monitors.
