The PreSonus Eris 4.5BT Bluetooth Studio Monitors deliver accurate, studio-quality sound in a compact desktop design. Ideal for home recording studios, music production, video editing, content creation, gaming and high-quality music listening, these active reference monitors combine detailed audio reproduction with flexible wired and wireless connectivity.

Powered by 50W Class AB amplification (25W per speaker), the Eris 4.5BT monitors feature a 4.5-inch woven-composite low-frequency driver and 1-inch ultra-low-mass silk-dome tweeter. The result is clear, balanced sound with controlled bass, detailed highs and accurate transient response across a 70 Hz–20 kHz frequency range.

Built-in Bluetooth 5.0 makes it easy to stream stereo audio wirelessly from compatible computers, smartphones and tablets. For studio equipment and other audio sources, the Eris 4.5BT also provides balanced ¼-inch TRS inputs, RCA inputs and a front-panel ⅛-inch stereo Aux input.

Integrated high- and low-frequency Acoustic Tuning controls allow the speakers to be adjusted to suit your room and listening preferences. A convenient front-panel volume control and integrated headphone amplifier with ⅛-inch headphone output make everyday monitoring and private listening simple.

Compact enough for a desktop but engineered with the sound quality expected from the PreSonus Eris range, the Eris 4.5BT active studio monitors are an excellent choice for bedroom studios, multimedia production, gaming setups and everyday listening.
