When you’re serious about creating music, you need monitor speakers that will reveal all of the flaws in your tracks and mixes. Eris professional studio monitors deliver the truth, thanks to very accurate response, tight bass, and clear upper end.

Cheap computer speakers and home-stereo speakers are designed to make music sound good and hide the flaws, while most low-cost studio monitors are hyped to sound good in the store showroom. If you mix on those speakers, you won’t hear problems that can show up in your final production.
Not so with PreSonus Eris-series active studio monitors. Thanks to well-designed Kevlar® low frequency transducers, low-mass silk-dome tweeters, responsive Class AB amplification, and professional acoustic-adjustment controls, Eris delivers the goods.

As you expect from PreSonus, they use quality components, are well constructed, and deliver professional audio quality. They’re lightweight and compact and look as professional as they sound.
But what really sets them apart from comparably priced systems are pro features such as user controls that allow you to tailor the speakers’ response to your needs.

Yet Eris-series speakers are ultra-affordable, making them a terrific value. And with three models, you can easily find the Eris monitor that best suits your studio needs.
