PreSonus Eris Pro 4 Coaxial Studio Monitor
The PreSonus Eris Pro 4 is a coaxial reference monitor whose single point-source design aligns the drivers for a wide sweet spot, precise imaging, and symmetrical dispersion. That makes it a strong fit for Dolby Atmos immersive rooms as well as conventional stereo mixing, with a detailed, less fatiguing sound.
A 1-inch ultra-low-mass silk-dome tweeter sits at the acoustic center of a 4.5-inch woven-composite woofer, and a ported enclosure with 80 watts of power reaches down to 50 Hz. Acoustic tuning controls with three-way Acoustic Space compensate for placement, flexible inputs connect any line-level source, and wall and ceiling mount provisions ease multi-channel installs. Sold individually.
