Description

The Eris Pro 8 is a coaxial studio monitor engineered to deliver a single acoustic point source and accurate stereo imaging. Its design prioritizes phase alignment between drivers to provide a wide sweet spot and consistent dispersion. This monitor is intended for critical listening in stereo and immersive mix environments.

The Eris Pro 8 pairs a 1.25-inch silk-dome tweeter coaxially mounted with an 8-inch woven-composite woofer for coherent imaging and detailed transient reproduction. The monitor uses 140 watts of Class AB amplification split between HF and LF sections to produce clear dynamics and punchy low end. A ported enclosure extends low-frequency response while maintaining control and clarity.

Measured performance includes a frequency range down to 35 Hz and up to 20 kHz, and a peak SPL of 108 dB at 1 meter. Crossover frequency is set at 3.1 kHz to optimize driver integration and transient response. Built-in protection covers RF interference, output-current limiting, over-temperature, turn-on/off transient, and a subsonic filter to preserve driver longevity.

Room tuning is provided by a three-way Acoustic Space control and continuously variable Mid and High frequency controls centered at 1 kHz and 10 kHz respectively. Low cut options include Flat, 80 Hz, and 100 Hz at -12 dB/octave to compensate for placement near walls or in corners. Inputs include balanced XLR and 1/4-inch TRS plus unbalanced RCA to support most line-level sources and interfaces.

This monitor is suitable for stereo mixing, immersive Dolby Atmos systems, and professional or home studio monitoring where imaging and phase coherence are critical. Its compact footprint and controlled low end make it practical for smaller mix rooms while still delivering reference-level dynamics. The coaxial point-source design helps in multi-channel arrays by maintaining consistent acoustic centers across channels.

The cabinet is constructed from vinyl-laminated medium-density fiberboard and includes provisions for wall or ceiling mounting for flexible installation. An IEC power connection and universal 100-240 VAC input simplify deployment in varied facilities. Overall build quality and integrated protection features make the Eris Pro 8 dependable for daily studio use.
