Description
The PreSonus Eris Sub 8BT is a compact 8″ studio subwoofer that takes a pair of desktop monitors down to 30 Hz and adds a Bluetooth 5.0 input to the system. PreSonus voiced it to match its compact Eris monitors, from the Eris 3.5 to the Eris Studio 5, for producers who want to hear the low end clearly while they mix.
Highlights
- Front-firing 8″ woven glass-fiber composite driver: 30–200 Hz, 100 dB peak SPL at 1 m.
- Class AB amplifier rated at 50 W RMS in PreSonus's specification table.
- Continuously variable low-pass filter from 50 to 130 Hz to blend with the main speakers.
- Switchable 80 Hz high-pass filter (12 dB/octave) on the signal passed on to the satellites.
- Balanced TRS and unbalanced RCA inputs with matching pass-through outputs, plus Bluetooth 5.0.
- Polarity switch (0°/180°), ground lift and a Power Saver mode that engages after 40 minutes.
In your setup
Connect your audio interface or DJ controller to the subwoofer's inputs, then run the pass-through outputs on to your monitors. With the high-pass filter on, the monitors no longer have to reproduce the deepest bass, and the low-pass knob sets where the sub takes over. If the bass sounds thin at your listening position, try the polarity switch; if you hear hum, use the ground lift. The vinyl-laminated MDF cabinet measures 250 × 299 × 323 mm and runs on 100–240 VAC through an IEC cable.
