PreSonus Eris Sub 8BT

Adding a subwoofer to full-range speakers enables you to hear the low-frequency foundation of your mix more accurately so you can make better-informed decisions and create more translatable mixes. The surprisingly loud, 100 watt Eris® Sub 8BT drops down to a molar-rattling 30 Hz, so you'll hear the full sonic spectrum and produce better mixes. For EDM and hip-hop producers, in particular, a subwoofer is a must-have.

Although compatible with a variety of full-range studio monitors, the Eris Sub 8BT compact studio subwoofer was designed to complement the voicing and frequency response of the full range of compact Eris studio monitors, from the ultra-affordable Eris 3.5 to the Eris Studio 5.

The first PreSonus® studio subwoofer to offer Bluetooth® 5.0 wireless connectivity, the Eris Sub 8BT provides flexible wired connection options, as well, making it easy to add it to just about any monitoring setup. Onboard controls let you effortlessly create a 2.1 monitoring system and tune it to your room. Highpass filter and lowpass filter (crossover) controls ensure the Eris Sub 8BT starts working at the precise frequency where your main monitors stop, avoiding the flabby, smudged, low-end mess that occurs without a crossover.

Add a PreSonus Eris Sub 8BT subwoofer to your compact full-range system and hear, with precision accuracy, the powerful low-frequency sound you've been missing.

Built For Your Room.
Thanks to flexible configuration and I/O options, you can configure the Eris® Sub 8BT exactly to your mixing and listening needs. Connect existing monitors via ¼-inch TRS or RCA cables, set the input level to your liking, and even invert the polarity. Pair a mobile device via Bluetooth® 5.0 wireless technology to quickly listen to a reference mix.
