PreSonus Eris Sub 8BT 8-Inch Bluetooth Subwoofer in Black

The PreSonus Eris Sub 8BT is an active studio subwoofer designed to extend the low-frequency response of a monitoring setup. It incorporates an 8-inch front-firing woofer made from woven composite material, powered by a 100-watt Class AB amplifier. This combination allows the unit to produce deep bass frequencies down to 30 Hz, providing a fuller representation of the audio spectrum for more accurate mixing and critical listening. The cabinet is constructed from vinyl-laminated medium-density fibreboard, which helps to reduce unwanted resonance. Key features include comprehensive connectivity with both balanced 1/4-inch TRS and unbalanced RCA inputs and outputs, alongside Bluetooth 5.0 for wireless streaming from mobile devices. The unit offers significant control over its integration into an existing system. It has a continuously variable low-pass filter (50-130 Hz) for setting the crossover point, a switchable 80 Hz high-pass filter for satellite speakers, polarity inversion, and an input level control with a range from -30 dB to +6 dB. This flexibility allows it to be tuned to suit different room acoustics and speaker combinations. This subwoofer is best suited for home studio producers, audio engineers, and enthusiasts looking to augment their nearfield monitor setup. It provides the necessary low-end extension to hear sub-bass elements clearly, which is crucial for mixing genres like electronic music, hip-hop, and film scoring. Its practical size and front-firing design make it suitable for placement under a desk or in a compact studio environment, helping users create more balanced and translation-friendly mixes by revealing the full sonic content of their work.
