You get nothing but the truth when you mix with Eris Pro 4 studio monitors. A symmetric design and consistent acoustic center ensure proper phase alignment with a wide sweet spot, a natural soundstage, and precise stereo imaging. Their detailed reproduction makes them ideal for complex stereo and multi-channel mix applications. The coaxial design provides a single acoustic point source, creating a natural listening experience with a three-dimensional soundstage and detailed transient response for clear definition and separation. Despite their compact size, the Eris Pro 4 offers the chest-thumping low-end you need for your home studio or professional mix rooms. Featuring a 1-inch silk-dome tweeter and a 4.5-inch woven-composite woofer driven by 80 watts of class AB power, they reach down to an impressive 50 Hz, delivering a powerful, natural, and fatigue-free listening experience. Onboard acoustic tuning controls compensate for room anomalies, so you can fine-tune your setup to any space. With flexible input and mounting options, the Eris Pro 4 easily integrates into any stereo or multi-channel system. Eris Pro 4.
