MACKIE CR4.5BT – 4.5" Self-Powered Studio Monitors with Bluetooth

A built-in Class-D amplifier delivers clear, dynamic sound with low distortion. A tone control knob lets you switch from neutral studio playback to progressive bass and treble boost for party mode or casual listening. A Desktop/Bookshelf switch optimizes dispersion based on position, while Bluetooth® 5.0 facilitates wireless streaming. With analog inputs (2x balanced/unbalanced TRS, 2x RCA, 1x 3.5mm) and a front-facing headphone output that automatically mutes the speakers, the CR4.5BT offers plug-and-play versatility for studio, gaming, multimedia, and entertainment.
