First-rate drivers and revolutionary EBM waveguide

The PreSonus Eris Studio 4 delivers crystal-clear sound thanks to its first-rate drivers. A 4.5-inch woven composite low-frequency transducer works jointly with a front-ported enclosure to produce ultratight lows and a constant dispersion pattern to minimize time smearing.

A 1-inch silk-dome high-frequency driver boasts accurate transient reproduction and, thanks to Presonus’s revolutionary EBM waveguide, a super wide sweet spot. What’s more, the EBM waveguide’s narrow vertical dispersion decreases reflections from your desk, supplying you with clean sound and a rock-solid stereo image.

Customizable sound reproduction for any room

Tailoring the PreSonus Eris Studio 4 to your room is a piece of cake by virtue of its plentiful acoustic tuning controls. Mid-frequency and high-frequency trim controls make compensating for your room’s deficiencies easy. You also get acoustic space control for taming the boundary issues that will inevitably arise if you place the Eris Studio 4 in a corner or near a wall.
