Don't let their size and price fool you: Eris E4.5 powered speakers deliver amazing sound quality in a compact package. Perfect for home studios or as high-fidelity replacements for computer speakers, Eris E4.5s pack a serious punch, thanks to 4.5-inch Kevlar(TM) low frequency transducers; 1-inch, low-mass, silk-dome tweeters; responsive 25W Class AB amplification per speaker; and professional acoustic-adjustment controls, the diminutive Eris E4.5 represents an outstanding value in its class. Unlike comparably priced studio monitors, Eris E4.5 has controls for simulating different listening environments and flattening frequency response to enable more accurate mixing.
