Estamos enviando NORMALMENTE.The PreSonus Eris E4.5 2-way active studio monitors give you a high-quality, high-value alternative to "computer" speakers. Eris employs a woven composite 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.
