Presonus Eris Sub8BT

Ideally suited to complement compact media reference and studio reference monitors without overshadowing them, the Eris® Sub 8BT delivers smooth, low-frequency transients, robust tuning controls and the convenience of Bluetooth® wireless connectivity to make them the perfect companion for your compact monitoring system.

The Eris® Sub 8BT active subwoofer features an 8-inch, front-firing, glass-composite woofer; 100W power; built-in tuning controls to complement your full-range monitors; Bluetooth® wireless input; and stereo 1/4" TRS and RCA inputs and outputs. A variable lowpass filter enables a seamless crossover transition, and a switchable 80 Hz highpass filter is provided for optimizing performance with satellite speakers.

The best 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 ultra-affordable Eris 3.5 to the Eris Studio 5.
