PreSonus Eris 3.5BT Studio Monitors (Pair)

The PreSonus Eris 3.5BT media reference monitors deliver studio-quality sound in a compact, versatile design suited for home studios, video production, gaming, and everyday music listening. With 25 watts per side of Class AB amplification, a 3.5-inch woven-composite woofer, and a 1-inch silk-dome tweeter, Eris 3.5BT provides clear, detailed audio with a strong low-end response.

Studio-Quality Sound in a Compact Design

The 3.5-inch woven-composite low-frequency transducer delivers articulate lows, while the ultra-low-mass silk-dome tweeter provides smooth, detailed high-frequency reproduction. Improved speaker voicing delivers richer lows and a smoother crossover transition for accurate transient response and comfortable extended listening.

Flexible Connectivity

Bluetooth 5.0 provides fast, reliable wireless stereo connectivity, while RCA, balanced 1/4-inch TRS, and front-panel 1/8-inch stereo Aux inputs accommodate a wide range of audio sources. An integrated headphone amplifier with a convenient front-panel output makes switching between speakers and headphones simple.

Easy Acoustic Adjustment

High- and low-frequency Acoustic Tuning controls allow you to fine-tune the speaker response for your listening environment. A front-panel volume control provides convenient access, while the rear-firing bass-reflex port helps extend low-frequency performance.
