Auralex SubDude


Anyone using the Auralex Acoustics SubDude underneath their powered subwoofer?

According to the web site:
"Its purpose is to prevent sound from transmitting through your subwoofer to surrounding surfaces."

Does the SubDude really work as advertised?

What sonic benefits have you experienced?

I have the ASC Subtrap which is similar but taller, raises the sub 18'' off the floor. My unit helped tighten the bass and helped with "room boom".

I've used the Auralex SubDude and Great Gramma with good results under my Velodyne subwoofers.

Here is an older thread where other A'gon members have shared their thoughts on the Auralex SubDude. Seems to be the real deal.
