PreSonus Eris Studio 4 4.5-inch 2-Way Active Studio Monitor (Single)

The PreSonus Eris Studio 4 delivers reference-quality sound made for both home studios and professional mix environments. Compact yet powerful, this studio monitor features a custom-designed EBM waveguide for precise high-frequency reproduction and a wide, controlled sweet spot ideal for critical listening. With 50W of bi-amplified Class AB power and a 4.5-inch woven-composite woofer, it offers deep bass response down to 55 Hz—no subwoofer required. Flexible input options (XLR, TRS, RCA) and room-calibrating acoustic tuning controls ensure optimal performance in any setup. The Eris Studio 4 stands out for its combination of accuracy, expressiveness, and robust build, making it a preferred choice for mixing, mastering, and detailed production tasks.
