The Auralex® SubDude-HT™ is a larger, lower-profile version of our classic SubDude™. The SubDude-HT is designed to work with most large-format home theater and hi-fi system subwoofers. This patented isolation platform features a stylish velour covering over an inert structural layer that floats on a cushion of acclaimed Auralex Platfoam™. This carefully engineered solution allows the true sound of your sub to come through. Its isolation system negates, and does not produce, resonant artifacts. This carefully chosen combination of specialized materials instantly diminishes structural vibrations, resulting in cleaner and tighter bass, reduced coloration and a more accurate low-frequency response. The SubDude-HT supports most subs up to 300lbs. and is an incredibly effective isolation platform that instantly improves subwoofer performance.
