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?

Thanks for bringing the SubDude back into my consciousness.
I just ordered one from Amazon - $49.95 delivered.

I've used a pair of these under my three-way speakers and I think they're great - a more thorough "decoupling" from the floor than what you'll get with a lot of feet-and-spike arrangements. The sheer height of the subdude also plays a role as far as taming the bass boominess.
I just wanted to bump this thread. I got a Subdude today and stuck it under my Linn Akurate 221 subwoofer. The improvement is immediate and obvious. For the price, everyone with a subwoofer should give it a try. Best $50 I ever spent on audio. I'm going to try their smaller pads under my monitors.
I used two of them under my old speakers because of floor vibration and they worked awesome. Still have one and gave the other to my brother in law because he's a guiatrist and plays some gigs on raised floors. He loves the thing.
