Presonus Eris 3.5 BT 2nd Gen Monitor de estúdio ativo 2 un.

Compact Studio Reference Monitors with Bluetooth

This pair of 2-way active nearfield monitors is built for small rooms and tight desks. Each speaker pairs a 3.5-inch woven-composite woofer with a 1-inch silk-dome tweeter, fed by 25 watts of Class AB power per channel. Improved voicing delivers richer lows and a smoother crossover transition.

What Sets the Eris 3.5 BT Apart

A 2.8 kHz crossover feeds a woven glass-fiber composite woofer and an ultra-low-mass silk-dome tweeter — the same transducer pairing used across the Eris family. Bluetooth 5.0 streams reliably from phones and laptops. A front-panel volume knob doubles as the headphone-amplifier level, and plugging in headphones mutes the speakers.

Tuned for Honest Playback Across 80 Hz – 20 kHz

Frequency response matters most when a monitor refuses to flatter the mix. This model delivers a flat, even response from 80 Hz to 20 kHz. Rear-panel High/Low Acoustic Tuning controls compensate for placement near walls.

• Woofer: 3.5-inch woven glass-fiber composite — tight, controlled low end without consumer-speaker boom
• Tweeter: 1-inch ultra-low-mass silk dome — refined highs with wide dispersion
• The 2.8 kHz crossover feeds both drivers for articulate transient reproduction

50 W of Class AB Power in a Desktop Footprint

Each speaker receives 25 watts from its own Class AB amplifier channel, totaling 50 watts per pair. Peak SPL reaches 98 dB at 1 meter — enough headroom for a small-to-medium room.

• Amplifier Power: 50 W total (25 W per side), Class AB dual amplification
• Peak SPL: 98 dB at 1 meter — clean, dynamic playback at any listening level
• Vinyl-laminated MDF cabinet measures just 21.0 × 14.1 × 16.4 cm per speaker

Bluetooth 5.0, Balanced TRS, RCA, and Acoustic Tuning

Four inputs cover every common source: Bluetooth 5.0, balanced 1/4-inch TRS, unbalanced RCA, and front-panel 1/8-inch stereo aux. Rear-panel High/Low Acoustic Tuning (±6 dB at 10 kHz and 100 Hz) adapts the monitors to the room. A Power Saver mode engages after 40 minutes of silence.

• Inputs: Bluetooth 5.0, 2× balanced 1/4-inch TRS, 2× unbalanced RCA, 1/8-inch stereo aux
• Acoustic Tuning: 2-band — High ±6 dB @ 10 kHz, Low ±6 dB @ 100 Hz
• Front-panel 1/8-inch headphone output with integrated headphone amplifier mutes the speakers automatically

Built for Bedroom Studios, Content Creators, and Desktop Listeners

The PreSonus Eris 3.5 BT 2nd Gen is the right choice for bedroom producers, podcasters, video editors, and gamers who need accurate monitoring in a compact footprint. Bluetooth 5.0 makes the pair equally comfortable as a hi-fi desktop speaker, while balanced TRS inputs welcome audio interfaces. Adding an Eris Sub 8BT turns the pair into a 2.1 system.

Audio engineers and producers worldwide rely on PreSonus recording tools, and the Eris family brings that same accuracy to compact desktop setups. A 2-year limited warranty backs every Eris monitor, reflecting PreSonus's confidence in the build quality of its reference series.
