Presonus Eris E3.5BT 2nd Gen Active Studio Monitors

The PreSonus Eris E3.5BT (2nd Generation) is a popular refresh of one of the most successful entry-level studio monitors on the market. Released late in 2023, the Gen 2 focuses on refined aesthetics, slightly improved low-end response, and more modern connectivity.

What’s New in the 2nd Gen?

While the core DNA remains the same, PreSonus made several “quality of life” updates:

• Voicing: The Gen 2 features a smoother crossover transition and a slightly punchier low end compared to the Gen 1.

• Power Save Mode: A new “Energy Conservation” mode kicks in after 40 minutes of inactivity (this can be toggled on/off via a rear switch).

• Visual Refresh: The front baffle is sleeker, and the power LED now glows purple when in standby mode.

• Volume Knob: The front volume knob has been updated for better tactile feel and visibility.
