PreSonus Eris Sub 8BT 8-inch Powered Bluetooth Studio Subwoofer

The PreSonus Eris Sub 8BT is a compact powered studio subwoofer built to extend the low-frequency response of desktop and nearfield monitoring systems. Its 8-inch front-firing woofer is driven by a built-in 100-watt amplifier, delivering tight and controlled bass that fills in the frequencies most small studio monitors cannot reproduce on their own. For home studios, podcast editing setups, and small mixing rooms, it provides the low-end foundation needed to make more confident decisions about bass content in your mixes.

Connectivity is a standout feature of the Sub 8BT, with RCA and 1/4-inch TRS inputs for wired integration alongside Bluetooth for wireless audio streaming. This dual-purpose design means the subwoofer can serve as part of a serious monitoring chain during production and double as a bass-enhanced speaker system for casual listening or reference playback. Its compact size allows it to tuck neatly under a desk or beside a pair of Eris monitors, making it a space-efficient addition to any small studio environment.
