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 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.
I used a similar Auralex Gramma under a Vel DD-15 for a time. It is effective in isolating the room from the sub, but not much good in communicating LF with precision. A Star Sound SP-1 with Audiopoints brass cups gives more delineation in the sub bass region and reduces muddiness that cabinet resonances will otherwise introduce into the upper bass and midrange.
Interesting. I need to do more listening. I think I might experiment by putting some weight on top of the sub to damp the movement a little. I've heard people putting bags of lead shot on top of subs.

On the subject of monitors, has anyone tried the Auralex Mopads? I've read mixed reviews. Some people seem to prefer the Primacoustic recoil stabilizer. Unfortunately, due to decorating factors and a small house, my monitors are on a built-in MDF cabinet. It's extremely solid, but it is coloring the sound somewhat.
