Presonus Eris Sub 8BT

The PreSonus Eris Sub 8BT is a compact, front-firing 8-inch studio subwoofer that brings the missing low end into your monitoring environment - wirelessly and with precision. With Bluetooth 5.0 connectivity and a wide range of wired input options, this subwoofer integrates easily with virtually any studio setup. It's designed to complement the entire line of compact Eris studio monitors, delivering a clean, tight bass response down to 30 Hz - perfect for EDM, hip-hop, and any genre that relies on powerful low-frequency content.

Powered by a 50W RMS Class AB amplifier, the Eris Sub 8BT delivers up to 100 dB SPL and features a variable lowpass filter (50"130 Hz) to precisely match your main monitors' crossover point. It also includes a defeatable highpass filter for routing cleaner signals to your satellites, plus controls for gain, polarity inversion, and ground lift. Rear-panel TRS and RCA inputs and outputs allow for flexible routing to full-range monitors, and the sub automatically enters power-saving mode after 40 minutes of inactivity.

Whether you're mixing, producing, or just enjoying your music, the Eris Sub 8BT offers an effortless upgrade to your sound with deeper bass, cleaner transitions, and wireless convenience - all housed in a compact, MDF cabinet that fits neatly into your home or project studio.
