MACKIE HR624MK2 - 6.7" Active Studio Monitor

MACKIE HR624MK2 – 6.7″ Active Studio Monitor

The Mackie HR624MK2 is a THX-certified two-way active studio monitor that delivers ultra-linear response and extended bass reproduction thanks to its rear passive radiator. Equipped with a 6.7″ ferrite woofer (45 Hz–6 kHz) and a 1″ neodymium dome tweeter (1.6 kHz–22 kHz), integrated Class AB amplifiers (100 W LF and 40 W HF), and a 6th-order active crossover DSP, it delivers up to 50 W RMS (150 W peak) while keeping distortion below 0.035% across the entire spectrum. Includes room-matching controls for bass (50 Hz shelving) and treble (10 kHz shelving), balanced XLR and TRS inputs, and unbalanced RCA inputs, plus thermal protection, power-up mute, and independent driver protection. Its rugged construction, zero-edge aluminum baffle cabinet, and convection cooling complete a design designed for critical mixing and mastering sessions.
