Mackie CR4.5BT Active 2-Way Multimedia Monitors with Bluetooth (Pair)

In a compact home studio or on a crowded desk, the Mackie CR4.5BT active monitors deliver clear, balanced sound without taking over the room. These 4.5-inch powered speakers connect to your computer, audio interface, or mobile device via Bluetooth, 1/4-inch TRS, RCA, or 1/8-inch aux, giving you flexible options for music production, gaming, or casual listening. The front-panel volume knob and headphone output keep control within easy reach, while the all-wood MDF cabinet and rear port ensure a solid low-end response. With 50 watts RMS of Class D amplification and a silk-dome tweeter, they reproduce your mix with surprising accuracy for their size.

The front headphone jack is perfect for late-night sessions, and the magnetic shielding prevents interference with nearby screens.

Good to know

The set includes a speaker-to-speaker cable and two connection cables (1/8" to RCA and 1/8" to 1/8"), so you can start listening right out of the box. The front panel features a combined power/Bluetooth pairing button and a volume control. The rear port enhances bass response, so allow some space behind the speakers for optimal performance. The monitors are sold as a pair with one active (amplified) speaker and one passive speaker connected by the included cable.
