The subwoofer you can get to put a little boom in your room, the surprisingly loud, 100 watt Eris Sub 8BT reaches down to a molar-rattling 30 Hz, so you'll hear the full sonic spectrum and produce better mixes. 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 a subwoofer 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, seamlessly extending the low-end of your monitoring setup. 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 all compact Eris studio monitors, from the affordable Eris 3.5 to the Eris Studio 5
