Choose options
PreSonus Eris Studio 4 is a compact studio monitor designed to deliver accurate and balanced sound in small rooms, edit suites and home studios. Featuring a 4.5-inch composite woofer and a 1-inch silk-dome tweeter, it offers clear audio reproduction with tight and controlled low-end response.
With its EBM (Elliptical Boundary Modeled) waveguide, high frequencies are dispersed widely and evenly, creating a larger sweet spot while minimizing desk reflections. The monitor also includes extensive acoustic tuning controls, such as a high-pass filter and independent mid and high frequency adjustments, making it easy to adapt to untreated spaces.
Eris Studio 4 provides balanced XLR and 1/4″ TRS inputs plus an unbalanced RCA input, ensuring compatibility with professional audio interfaces, mixers and other equipment. Its solid build, reliable tone and affordability make it an ideal choice for producers working in limited studio space.
