Description
The Eris Sub 8BT is a compact 8-inch front-firing studio subwoofer designed to extend the low-frequency range of compact studio monitors and reveal the bass foundation of your mixes. It pairs easily with small desktop monitors to create a controlled 2.1 monitoring system. The unit emphasizes accurate bass reproduction down to 30 Hz to help you make informed mixing decisions.
Key features include an 8-inch woven glass fiber composite low-frequency driver, Bluetooth 5.0 wireless stereo input, and a Class AB amplifier delivering 50W RMS and 100 dB peak output. The subwoofer provides a continuously variable lowpass filter from 50 Hz to 130 Hz and an input gain control from -30 dB to +6 dB. A defeatable highpass filter removes content below 80 Hz from the satellite outputs, allowing seamless integration with full-range monitors.
Performance-spec highlights are a frequency response that extends from 30 Hz to 200 Hz and a peak SPL of 100 dB measured at 1 meter. The onboard crossover controls let you set the lowpass frequency where the sub begins to take over from the main speakers, reducing low-end smearing and preserving mix clarity. Protection circuitry covers RF interference, output-current limiting, over-temperature, turn-on/off transients, and subsonic filtering.
Connectivity is comprehensive for compact studio systems: left/right balanced 1/4-inch TRS and unbalanced RCA inputs plus matched pass-through outputs for connecting satellite speakers. The Eris Sub 8BT also supports Bluetooth 5.0 wireless audio for quick source playback and monitoring checks. An IEC power connection and a Power Saver mode that engages after 40 minutes help manage energy use in the studio.
This subwoofer is suited to electronic music producers, hip-hop and beat makers, and project-studio engineers who need a compact footprint without sacrificing low-frequency insight. It enhances translation on systems ranging from nearfield desktop setups to small control rooms by providing a solid bass reference. The unit’s crossover flexibility makes it suitable for pairing with the Eris line of compact monitors as well as many other small full-range speakers.
Installation and setup are straightforward thanks to clearly labeled controls and simple pass-through wiring for satellites. The cabinet is constructed from vinyl-laminated medium-density fiberboard for acoustic stability and consistent performance. Controls for polarity inversion and ground lift aid in handling room and wiring issues during setup.
Overall, the Eris Sub 8BT provides a compact, controllable low-frequency extension that improves mix decisions and playback realism. Bluetooth 5.0 adds convenience for reference listening while the analog I/O and tuning controls ensure professional integration into studio monitoring systems. The combination of accurate bass response and user-focused controls delivers measurable value for critical listening environments.
