Powerful 100-watt Subwoofer with Bluetooth

There’s standard bass-frequency monitoring, and then there’s the PreSonus Eris Sub 8BT powered Bluetooth studio subwoofer. Designed with versatile setup options and intuitive control parameters, this 100-watt subwoofer is an ideal solution for small studio monitoring and hi-fi audio playback. Its 8-inch low-frequency driver delivers powerful, controlled bass that lets you accurately track your low end. While it pairs perfectly with Eris Pro and Eris Studio series monitors, the Eris Sub 8BT is a valuable addition to virtually any monitoring setup, delivering clear and reliable low-frequency performance.

Seamless User Controls Produce a Signature Sound

Different studios demand different configurations, and the Eris Sub 8BT is built to integrate easily into smaller-scale workspaces. With RCA, 1/4-inch TRS, and Bluetooth connectivity, the rear panel offers flexible hookup options for a wide range of gear. Once connected, onboard high-pass and low-pass filter controls allow you to precisely shape the frequency range of your system. Fine-tuning your low end during critical monitoring situations is quick and effortless with the Eris Sub 8BT.

What PreSonus Says...

Adding a subwoofer to full-range speakers lets you hear the low-frequency foundation of your mix with greater accuracy, helping you make better-informed decisions and create mixes that translate consistently. The compact Eris® Sub 8BT delivers surprisingly powerful performance from its 100-watt design, reaching down to an impressive 30 Hz so you can hear the full sonic spectrum. This makes it an essential tool for producers working in bass-heavy genres such as EDM and hip-hop.

Compatible with a wide range of full-range studio monitors, the Eris Sub 8BT is specifically voiced to complement the entire lineup of compact Eris studio monitors, from the Eris 3.5 through the Eris Studio 5. Its compact, front-firing design makes it easy to integrate into smaller studio environments without sacrificing low-end impact.

As the first PreSonus® studio subwoofer to feature Bluetooth® 5.0 wireless connectivity, the Eris Sub 8BT also offers flexible wired connection options, making it simple to add to almost any monitoring setup. Onboard controls allow you to easily create and fine-tune a 2.1 monitoring system for your room. High-pass and low-pass filter controls ensure seamless integration with your main monitors, preventing muddy or uncontrolled low-end buildup.
