Description
The Eris Pro 4 is a single-point source coaxial studio monitor designed to deliver clear, accurate audio reproduction for mixing and monitoring. It combines a 4.5in woven-composite woofer and a 1in ultra-low mass silk-dome tweeter in a coaxial alignment to improve phase coherence and stereo imaging. Sold individually, each monitor is engineered for precise transient response and extended listening sessions.
Key features include a coaxial driver arrangement that widens the sweet spot and improves phase alignment, an 80W Class AB amplifier system split between high and low-frequency sections, and acoustic tuning controls for room placement compensation. The speaker provides a 3.4 kHz crossover point to align the woofer and tweeter and minimize midrange interference. Acoustic Space, High Frequency and Mid Frequency controls let you adapt the monitor to near-wall or corner placement.
Performance specifications include a frequency response of 50 Hz to 20 kHz and a measured peak SPL of 99 dB at 1 meter. The high-frequency section is driven by 35 Watts while the low-frequency section has 45 Watts of power for a total of 80 Watts. A tuned ported enclosure extends low-frequency performance down to approximately 50 Hz for punchy, controlled bass.
Connectivity is flexible with balanced XLR and 1/4in TRS inputs plus an unbalanced RCA input for consumer sources. Input impedance is 10 kOhm to accommodate a variety of line-level sources such as audio interfaces, mixers, and playback devices. The rear panel layout and support for wall and ceiling mounting make system integration straightforward.
The Eris Pro 4 is suited to nearfield studio mixing, small Dolby Atmos monitoring setups, and desktop production systems where accurate imaging and transient detail matter. Its coaxial design reduces phase anomalies encountered in multi-driver layouts, which improves clarity for speech, percussion, and transient-rich material. These characteristics make the monitor appropriate for editors, producers, and content creators who require reliable reference sound in compact rooms.
Build quality includes a vinyl-laminated MDF cabinet and rock-solid protection circuitry for RF interference, over-temperature, output-current limiting, and turn-on/off transient suppression. A power saver mode engages after 40 minutes of inactivity to reduce power draw. Overall, the Eris Pro 4 balances compact footprint, tunable response, and professional features in a studio monitor package.
