PreSonus Eris 4.5BT - 2-Pack of 50W 4.5-inch Powered 2-Way Studio Monitors with Bluetooth in Black Finish

The PreSonus Eris 4.5BT is a 2-pack of compact, high-performance powered studio monitors designed to provide studio-quality sound in a sleek and space-efficient form factor. Whether you're working in a bedroom studio, producing video content, or setting up a high-fidelity gaming system, the Eris 4.5BT is an excellent choice. With their 50W (25W per speaker) Class AB dual amplification, these monitors deliver impressive audio with clear, accurate sound reproduction. The 4.5-inch woven-composite low-frequency driver provides deep, tight bass that you can feel, while the 1-inch silk-dome tweeter ensures smooth, refined high frequencies, creating a balanced sound profile across the entire frequency range. The monitors' wide sound dispersion pattern allows for a larger optimal listening area, making them ideal for various listening environments.

The Eris 4.5BT monitors offer a frequency response of 70 Hz to 20 kHz, delivering a full-range sound suitable for both professional production and casual listening. The advanced voicing of these speakers results in richer low-end response, smoother crossover transitions, and a less fatiguing listening experience. For further customization, the monitors feature high- and low-frequency acoustic tuning controls, enabling you to adjust the speakers' response to fit the acoustics of your room. This allows for the most accurate sonic reproduction possible, giving you a consistent and reliable listening experience no matter the space.

Designed with flexibility in mind, the Eris 4.5BT includes multiple input options to connect a wide range of audio sources. These include two balanced 1/4-inch TRS inputs, two unbalanced RCA inputs, and a stereo 1/8-inch input. In addition to wired connections, the Eris 4.5BT features fast, reliable Bluetooth 5.0 connectivity for wireless streaming from smartphones, tablets, or laptops. The front-panel volume knob lets you control both the power amp and the headphone amplifier, with a dedicated 1/8-inch headphone output for convenient monitoring. For those needing more low-end, the Eris 4.5BT can be paired with the Eris Sub8 BT to create a perfectly matched 2.1 sound system.
