PreSonus Eris 4.5 High-Definition 2-Way Nearfield Studio Monitors Speakers
Ultra-compact, budget-priced 2-way monitor speakers.
When it's time to replace those cheap "computer" speakers with serious 2-way professional studio monitors, you're ready for the Eris E4.5. With Kevlar low frequency transducers, low-mass silk-dome tweeters, responsive Class AB amplification, and professional acoustic-adjustment controls, the compact Eris E5 represents an outstanding value in its class. It includes RF shielding, current-output limiting, over-temperature protection, and subsonic protection, and unlike comparably priced studio monitors, it has controls for simulating different listening environments and flattening frequency response to enable accurate mixing.
