Active Monitors PreSonus Eris 3.5 BT 50W

The PreSonus Eris 3.5 BT are compact active studio monitors that combine Bluetooth wireless playback with a 50W built-in amplification system. Each speaker houses a 3.5-inch Kevlar woofer and a 1-inch silk dome tweeter designed to deliver a balanced, flat frequency response for accurate listening and mixing in small rooms. Rear bass ports and onboard acoustic tuning allow adjustment to different room acoustics, while the compact footprint makes these monitors suitable for desktop setups and limited spaces.

Advantages

Bluetooth connectivity enables straightforward wireless streaming from smartphones, tablets, or laptops without sacrificing monitoring capabilities. The Kevlar woofer provides controlled low-frequency response with reduced distortion, and the silk dome tweeter produces clear high frequencies with a smooth top end. Integrated amplification simplifies setup by removing the need for external power amps, and the acoustic tuning controls and rear-firing ports help optimize bass and midrange behavior in varied listening environments.

Suitable for

• Small home studios and project studios for tracking and mixing
• Desktop computer audio for content creation and editing
• Multimedia playback in bedrooms, offices, or small listening areas
• Reference monitoring where a neutral, flat response is required

Key specifications

• Total amplification power: 50 watts

How to use

Position the monitors on stands or a desk at ear height, forming an equilateral triangle with the listening position for best stereo imaging. Connect a source via Bluetooth for wireless playback or use analog inputs for direct connection to audio interfaces, mixers, or computers. Adjust the acoustic tuning controls to compensate for room boundary effects or placement near walls; increase or decrease low-frequency and high-frequency settings until the tonal balance suits your environment. Allow a short warm-up period after power-on for consistent performance.

Usage recommendations

For accurate mixing, use the Eris 3.5 BT in a quiet listening environment with minimal reflective surfaces. Place the monitors symmetrically relative to room boundaries and avoid blocking the rear bass ports. When using Bluetooth, keep the source device within recommended range and disable any device-level equalizers for a neutral reference signal.
