PreSonus Eris Sub 8 BT - 50W 8-inch Powered Studio Subwoofer with Bluetooth in Black Finish

The PreSonus Eris Sub 8 BT is a powerful and compact 8-inch powered studio subwoofer designed to enhance your full-range monitoring system by providing deep, precise low-frequency reproduction. Whether you're producing EDM, hip-hop, or any genre that requires accurate bass response, this subwoofer is a must-have tool. With 50W RMS of Class AB amplification, the Eris Sub 8 BT delivers a peak output of 100 dB SPL at 1 meter, allowing you to feel the full spectrum of sound from a molar-rattling 30 Hz all the way up to 200 Hz. By accurately reproducing these low frequencies, the Eris Sub 8 BT enables better-informed decisions in your mix, improving the translatability of your work across various listening systems.

Designed to integrate seamlessly with PreSonus' Eris-series studio monitors, the Eris Sub 8 BT complements the frequency response and voicing of the entire Eris lineup, from the ultra-compact Eris 3.5 to the more powerful Eris Studio 5. This synergy allows for a more balanced, cohesive sound when creating a 2.1 monitoring setup. Whether you're in a small bedroom studio or a larger space, the Eris Sub 8 BT provides the deep, punchy bass you need without overwhelming your monitors or your room.

The subwoofer features Bluetooth 5.0 wireless audio connectivity, the first of its kind for PreSonus studio subwoofers, allowing you to connect wirelessly to compatible devices and reduce cable clutter. Additionally, the Eris Sub 8 BT includes flexible wired connection options, including balanced 1/4-inch TRS and unbalanced RCA inputs, as well as passthrough outputs for connecting additional speakers. Onboard controls such as the continuously variable lowpass filter (50 Hz to 130 Hz) and defeatable highpass filter ensure that your main monitors and subwoofer work together in perfect harmony, avoiding any unwanted low-end distortion. The polarity invert switch provides additional fine-tuning, ensuring the phase alignment of your system for optimal sound performance.

Equipped with a robust set of protection features, including RF interference, output-current limiting, overtemperature protection, and a subsonic filter, the Eris Sub 8 BT ensures reliable, consistent performance throughout your work. Its Power Saver mode, which engages after 40 minutes of inactivity, helps conserve energy when not in use. This subwoofer is perfect for building a compact but powerful monitoring system that provides deep, accurate bass for critical listening, mixing, and production.
