About the RF900
The Harmonix RF-900M Million (also referred to as RF-900 M Million) are high-end spike bases/tuning feet manufactured by Combak Corporation, used under spike-equipped loudspeakers, amplifiers, and other audio components. They improve spatial imaging, naturalness, detail resolution, transparency, and three-dimensional soundstaging through resonance transformation technology. Made with premium metal and wood hybrid construction, they offer synergistic effects when combined with other Harmonix products like TU-333EX insulators. Available in sets of 4 or 8, with elegant design in metal and wood finishes (gold/black options in series). Highly praised in reviews for richer tonal palette, liquidity, and musical flow.
