PreSonus Eris Sub 8BT — 8-inch Active Studio Subwoofer with Bluetooth for Multimedia, Gaming, Studio-Quality Music Production Black

Big sub-low end. 8-inch front-firing driver delivers smooth, accurate sub-low frequencies. Bluetooth 5.0 stereo input ensures outstanding wireless audio quality. Power to spare: 100W Class AB amplifier (50W RMS) delivers 100 dB SPL peak output (@ 1 meter) output with minimal distortion. That’s plenty loud! Deep low frequencies: 30 Hz to 200 Hz frequency response. Input gain control gives -30 dB to +6 dB of continuously variable output. Continuously variable lowpass filter keeps resonances in the 50 Hz to 130 Hz range. Defeatable highpass filter removes sub-80 Hz frequency content from the full-range signal sent to the main speakers for a perfect match. Left and right, balanced ¼-inch TRS and unbalanced RCA main inputs ensure easy wired connectivity — or go wireless with Bluetooth. Left and right balanced ¼-inch TRS and unbalanced RCA pass-through outputs onboard for connecting satellite speakers. Polarity invert switch corrects phase-cancellation issues.
