The Auralex SubDude is a 15" x 15" x 2.5" Subwoofer Isolation Platform wrapped with a cleanable black velour to fit any room setting. Its purpose is to prevent sound from transmitting through your subwoofer to surrounding surfaces.
Subwoofer speakers create big vibrations (low frequencies) that you can feel in the floor and in objects placed nearby. When the source of the vibrations is coupled directly to the floor it causes these objects to vibrate or resonate”not only at the fundamental pitch the source is creating but also at harmonic frequencies that discolor the true sound from the source. Now you have two (or more) objects vibrating, which creates an acoustical problem called "secondary resonance".
The most noticeable effect of the Auralex SubDude is on harmonic frequencies above 100 Hz. This is the harmonic range above the fundamental the sub is recreating, allowing you to hear a more true bass tone below 100 Hz by eliminating upper harmonic resonances. This translates to the listener as more accuracy in the low end, and a cleaner (less muddy) crossover between the sub and your full range LCR channels. The SubDude Isolation Platform effectively reduces secondary resonance by decoupling your subwoofer from the floor so you hear your sub and not the vibration of the other objects in your listening environment.
When speakers are tested in anechoic chambers, they are isolated from objects around them that could introduce resonance. With the Auralex SubDude Isolation Platform, you can recreate a similar scenario in your living room.

I have been using the SubDude on my studio monitor sub and on my consumer surround sub for the past year. I perceive a subtle difference in low end isolation in my studio, but would deem both as effective. Obviously sub placement and room treatment are the largest factors in balancing the listening area, but the SubDude does what the ad describes. The decoupling effect would be valuable to those in multi-unit dwellings to reduce floor/wall vibrations as well.
