PreSonus E4.5 BT Overview

Designed for content creators, gamers, and mixing engineers, the PreSonus ERIS BT 4.5 Bluetooth Studio Monitors provide a clear, accurate frequency response and a wide variety of inputs.

These are small monitors, giving you 4.5" woven composite woofers and 1" silk dome tweeters for a balanced sound across its 70 Hz to 20 kHz frequency range. You can input sound to the monitors over 1/4" TRS jacks, unbalanced RCA inputs, a 3.5mm auxiliary input, and Bluetooth 5.0 streaming. Whether you're monitoring from an audio interface, a computer output, a receiver, or a mobile device, these monitors can accommodate you.

Change the level with a prominent front-panel volume control. On the rear, you'll find both high and low EQ knobs for tuning the monitors to your room. There is 50W of Class AB power supplied (25W per side) giving you a powerful punch for the size. When you need to work or listen late at night, you'll appreciate the built-in headphone amplifier and 3.5mm headphone output for silent monitoring.
