PreSonus ERIS 3.5BT 3.5-inch Woven Woofer / 1-inch Silk-Dome Tweeter / Bluetooth 5.0 / 25W per Side (Pair)

Description

The Eris 3.5BT 2nd Gen are compact active media reference monitors designed to deliver accurate, room-adaptable sound in small production and listening environments. These two-way monitors combine a 3.5-inch woven glass fiber woofer and a 1-inch silk-dome tweeter to offer a balanced frequency response that preserves detail across the spectrum. The monitors provide studio-quality clarity while remaining compact enough for desktop use and constrained rooms.

Key features include Bluetooth 5.0 stereo wireless input, Class AB amplification delivering 25 watts per side, and front-panel headphone output with integrated amplifier. The silk-dome tweeter offers refined high-frequency detail while the woven-composite woofer provides controlled low-end impact for accurate monitoring. High- and low-frequency Acoustic Tuning controls allow you to adapt the speaker response to room acoustics and placement.

Technical performance supports an 80 Hz to 20 kHz frequency range and a peak SPL of 98 dB at 1 meter, with an internal crossover set at 2.8 kHz for smooth driver integration. The onboard protections guard against RF interference, output-current limiting, over-temperature, turn-on/off transients, and subsonic signals to protect driver and amplifier components. A power saver mode engages after 40 minutes of inactivity to reduce power consumption.

Connectivity covers both wired and wireless workflows – balanced 1/4-inch TRS inputs, unbalanced stereo 1/8-inch and RCA inputs, plus fast stereo Bluetooth 5.0 for mobile and wireless sources. A front-panel level control adjusts both the amplifier and the loud front headphone amplifier; inserting headphones mutes the speakers for private monitoring. Cables are included to support immediate integration with existing audio interfaces and desktop setups.

Use cases for the Eris 3.5BT include bedroom studios, video editing desks, small podcast setups, gaming rigs, and content creation workstations that require accurate nearfield monitoring without a large footprint. The speakers aim to reproduce mixes honestly so that critical decisions translate well to other systems. They also pair with the Eris Sub8 BT to expand low-frequency extension when a 2.1 system is desired.

Installation and operation are straightforward – position the monitors at ear height, use the HF and LF controls to compensate for boundary gain or room coloration, and connect sources via Bluetooth or wired inputs. The vinyl-laminated MDF cabinets and robust protection circuitry provide durable daily use while preserving sonic integrity. Overall, the Eris 3.5BT balances accurate monitoring features and convenient connectivity in a compact package.
