Overview
 
PreSonus® Eris-series studio monitors are used worldwide by audio engineers who need to hear every detail of their recordings. Ideal for music lovers, content creators, and gamers, the Eris E4.5 media reference monitors deliver the same studio-quality sound and accurate frequency response professional Eris-series studio monitors are known for, in an elegant, compact form ideal for home use. Features like onboard EQ controls and an integrated headphone amplifier, make it easy to cater your Eris E4.5 monitors to taste for a customized listening experience. Every Eris-series studio monitor utilizes a woven composite low-frequency driver. The weave and nature of the Eris E4.5 speakers’ 4.5-inch woofer result in tight bass that you can feel, as well as a cleaner overall sound. The one-inch silk-dome tweeter produces a smooth and refined sound, accurately reproducing transients and high frequencies. The tweeter is designed to radiate sound with a fairly wide pattern, creating a large optimal listening area or “sweet spot” so you can move around and still hear an accurate stereo image. With 25 watts per side of onboard power, Eris 4.5 monitor speakers pack a serious punch, while still delivering clear, accurate audio.
