PreSonus Eris E4.5 (Pair)

Description

The PreSonus Eris E4.5 2-way active studio monitors give you a high-quality, high-value alternative to “computer” speakers. Eris employs a Kevlar woofer, a low-mass silk-dome tweeter, Class AB amplification, and professional acoustic-adjustment controls to deliver true studio-monitor accuracy, at a price point that’s flooded with ho-hum “multimedia” speakers. And unlike comparably priced studio monitors, Eris gives you controls for flattening frequency response to facilitate accurate mixing. Need accurate monitors but don’t want to break the bank? You should give the PreSonus Eris E4.5 a serious audition.

Nothing But the Truth.
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.

Making Connections.
Eris monitors give you three different types of inputs (RCA/TRS/XLR) so you can use them with a wide variety of audio sources.
