Mackie CR4BT 4-Inch 2-Way Active Studio Monitors with Bluetooth

The Mackie CR4BT studio monitors deliver professional sound quality in a compact, desk-friendly design. Featuring a 4″ polypropylene woofer and 0.75″ silk dome tweeter, these two-way active monitors offer clear, accurate audio reproduction for home studios, content creation, and casual listening. With up to 28 W RMS (50 W peak) of Class AB power and custom-tuned rear ports, you get deep bass extension and pristine clarity across a 70 Hz–20 kHz frequency range.

Bluetooth 3.0 connectivity lets you stream music wirelessly, while flexible inputs (1/4″ TRS, RCA, and front-panel 3.5 mm) accommodate any source. A speaker-placement switch positions the volume knob on either side of your desk, and a front-facing headphone jack provides immediate private monitoring.
