PreSonus Eris Studio 4 (Single) 4.5-inch 2-Way Active Studio Monitors with EBM Wave Guide

Set up your studio monitors for your room.

Eris® Studio 4 active monitors are equipped with Acoustic Tuning controls to ensure the flattest response in your mix environment. You get Low Cut, Mid, and High controls, as well as three-way Acoustic Space tuning that makes it easy to compensate for the boundary bass boost that occurs when a speaker is placed too close to a wall.

Honest. Expressive. Powerful.

Like all PreSonus® studio monitors, the Eris® Studio 4 offers consistent, accurate listening. Their stylish design makes them a welcome addition to any mix space, and their smooth, incredibly even frequency response ensures that your mixes will sound great everywhere.
