Kevlar woofers and silk-dome tweeters.

PreSonus Eris E4.5 powered studio monitors are used worldwide by studio engineers who need to hear every detail of their recordings. Eris E4.5 active monitors boast 4.5" woofers and 1" silk-dome tweeters. Ideal for gaming and home video production, the Eris E4.5 delivers studio-quality sound yet is compact enough to fit almost anywhere. You get the flexibility of rear-panel, 1/4" TRS and RCA inputs; front-panel 1/8” stereo, unbalanced line inputs for use with mobile audio devices; a convenient front-panel volume control; and an integrated headphone amplifier. Fine-tune the speaker’s response with low- and high-frequency tuning controls. It may be small, but the E4.5 is loud—as well as clear—thanks to a 25W per side Class-A/B power amp.


  • 4.5" Kevlar low-frequency transducer
  • 1" silk-dome, high-frequency transducer
  • 70Hz–20kHz frequency response
  • 50W peak Class-A/B biamplification

Ditch those tired old computer speakers and step up to serious studio monitors—order today.
