Auralex SubDude

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.

Thanks guys!

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.
