Mackie HR624 Mk1 Studio Monitors – Great Sound, Honest Condition
These great sounding speakers are the MK1 which were still housed in wood instead of the plastic the current models use. Comes with 2X 5m blue Profigold RCA cables.
Solid, accurate, and still punching well above their weight—the Mackie HR624 Mk1 active studio monitors remain a favorite for mixing, tracking, and critical listening. These are the real deal: bi-amped, time-aligned, with that signature High Resolution waveguide and titanium-dome tweeter that delivers a wide, stable sweet spot and honest, uncolored sound.
Both units are fully functional—clean power-on, no buzzes, no distortion, and all acoustic space controls working as they should. Cosmetically, they show light wear consistent with studio use. Note: the MDF veneer on one unit has lifted slightly on the top edge edge—a super common issue with these monitors due to age, as you’ll see in the photos. It doesn’t affect performance in any way, and the cabinet remains structurally solid.
If you’re after reliable nearfields for a home or project studio—without the hype or the markup—these are a low-key, high-value pick. Tested, loved, and ready to go.
No fluff. Just clear sound and honest gear.Used Mackie HR624 THX studio monitors.
