Auralex SubDude-HT Subwoofer Isolator Preview
The powered subwoofer in the corner of the room can really shake the place with your home theatre system cranked up. Fortunately, audio engineers at speaker companies tackle problems like the causes of massive vibrations – and no, not everybody wants to feel their walls vibrate.
The nifty little device called the SubDude-HT works as an add-on to your existing powered subwoofer. It basically raises the woofer off the ground, and isolates it from whatever platform it may be resting on. Any frequency from 100Hz and up should feel cleaner and less noisy, even when the volume is increased.
