The Auralex® SubDude-HT™ is a larger, lower profile version of our classic SubDude II.™ The SubDude-HT is designed to work with most home theater subwoofers.

The SubDude-HT’s expanded size accommodates popular, larger-footprint home theater subwoofers.  The design features a functionally inert 3/4", velour-covered, MDF platform supported by a 1" base layer of Auralex Platfoam as an isolation boundary to decouple the subwoofer from the floor. This combination of materials diminishes structural vibrations resulting in cleaner and tighter bass, reduced coloration, and a more accurate low-frequency response.
