PRESONUS Studio Monitor ERIS 4.5 BT

PreSonus Eris 4.5 BT for compact studio listening

PRESONUS Studio Monitor ERIS 4.5 BT is a pair of active media reference monitors with Bluetooth support. It suits buyers who want a compact speaker setup for home content creation, gaming, or everyday listening with wired and wireless input options.

Bluetooth and wired inputs

The Eris 4.5 BT supports Bluetooth 5.0 and also gives you rear-panel balanced 1/4-inch TRS and unbalanced RCA inputs, plus a front 1/8-inch stereo input. That makes it easier to connect a computer, audio interface, phone, or other line-level source without changing your setup.

Built as a 2-way active pair

This model is a 2-way active monitor pair with one active speaker and one passive speaker. The active unit handles the connections and powers the companion speaker, which keeps the system simple for a desktop or small-room placement.

Compact nearfield sound

Each speaker uses a 4.5-inch low-frequency driver and a 1-inch silk dome high-frequency driver. The published frequency response is 70 Hz to 20 kHz, which makes it a practical match for close-up listening where clear mids and highs matter more than room-shaking bass.

Useful for desktop setups

The cabinet is vinyl-laminated MDF, and the published peak SPL is 100 dB at 1 meter. If you are shopping for a compact monitor for a desk, study corner, or small creative space, this model is designed for that kind of nearfield use rather than large-room playback.
