PreSonus Eris Sub 8BT Compact 8-inch, front-firing studio subwoofer with Bluetooth® wireless

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 1/4-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.

Symmetric response.

The Eris Pro 8's coaxial design provide a symmetrical dispersion resulting in a crisper stereo image, greater soundstage depth, and superior separation between components in a complex mix.

Set up your studio monitors for your room.

Acoustic Tuning controls ensure you'll get the flattest frequency response possible in your mix environment. You get Low Cut, Mid, and High controls, as well as 3-way Acoustic Space tuning that allows you to easily compensate for the sonic consequences of speaker placement against a wall or in a corner.
