PreSonus Eris Sub8 BT – Active Studio Subwoofer with Bluetooth for 2.1 Monitoring If you want full control over the lowest frequencies in your mixes, you need a tool that reveals what standard studio monitors simply cannot reproduce. The PreSonus Eris Sub8 BT is a compact yet powerful studio subwoofer that lets you hear the full sonic spectrum – from deep bass to detailed low-end clarity. With it, your productions become more balanced, professional, and translate better across different playback systems.

Key Features This subwoofer is equipped with an 8-inch woven glass-fiber composite driver that delivers tight and accurate bass response. The built-in Class AB amplifier with 50W RMS provides solid power and control, while the frequency response reaching down to 30 Hz ensures you hear the deepest elements of your mix. Additionally, Bluetooth® 5.0 connectivity allows for wireless audio streaming, increasing flexibility in any studio setup.

Accurate Low-End Control for Any Studio Environment With adjustable high-pass and low-pass filters, you can perfectly match the subwoofer to your monitors and room acoustics. The continuously variable crossover (50–130 Hz) ensures seamless integration with your main speakers, eliminating muddy or undefined bass. The high-pass filter removes unwanted low frequencies from the signal sent to your monitors, improving overall clarity. A polarity switch further helps optimize phase alignment within your setup.

It performs exceptionally well in both home studios and professional production environments. When paired with PreSonus Eris monitors, it creates a complete and powerful 2.1 monitoring system.
