The PreSonus Eris E3.5 are true studio monitors designed for multimedia, gaming, watching movies, or producing music. They feature 3.5-inch woven composite drivers for a powerful bass response and accurate sound, along with 1-inch ultra-low-mass silk-dome tweeters to eliminate harshness and provide balanced high-frequency sound. These monitors offer acoustic tuning for pristine sound quality in any room and have a crossover frequency of 2.8 kHz. They include Studio One Prime software for easy music production and the Studio Magic Plug-In Suite, valued at over $1000, offering additional software instruments and effects. Registration of any new PreSonus studio monitor to a My.PreSonus account unlocks this software. Convenience features include a stereo aux input for smartphones, a headphone jack for private listening, and front-panel controls for volume and power. The 50-watt Class AB amplification (25 watts per speaker) provides ample volume and headroom for nearfield monitoring. The studio-quality industrial design ensures they look as good as they sound. Protection features include RF interference, output-current limiting, over-temperature, and turn-on/off transient protection.
