The PreSonus Eris Pro 4 is a high-performance, active studio monitor that utilizes a coaxial design to provide a single-point source for professional-grade audio monitoring. By placing the 1-inch silk-dome tweeter directly in the center of the 4-inch woven-composite low-frequency driver, the Eris Pro 4 achieves superior phase alignment and a symmetrical dispersion pattern. This results in a remarkably wide "sweet spot" and precise stereo imaging, making it an excellent choice for compact home studios, broadcast booths, and immersive audio setups like Dolby Atmos where space and acoustic accuracy are paramount.

Powered by 80W of Class AB amplification, the Eris Pro 4 delivers a surprisingly punchy and detailed sound across a 50 Hz to 20 kHz frequency range. The rear panel is equipped with comprehensive Acoustic Tuning controls, including a three-position Acoustic Space switch to compensate for wall placement and dedicated High and Mid-frequency adjustments to tailor the sound to your specific room environment. With balanced XLR and 1/4-inch TRS inputs alongside unbalanced RCA connections, this monitor integrates seamlessly into any professional signal chain, offering a flat, transparent response for critical mixing and mastering tasks.
