Subwoofer Isolation Platform: The Auralex SubDude-II is a low-profile subwoofer isolation platform and is perfect for small subwoofers in home theaters and hi-fi systems. The SubDude-II subwoofer isolation platform utilizes Auralex technology and carefully chosen combination of specialized materials to instantly diminish structural vibrations, resulting in cleaner and tighter bass, reduced coloration and a more accurate low-frequency response.

Sound Improvements: The SubDude-II is an incredibly effective isolation platform that instantly improves your subwoofer's performance. This carefully engineered solution allows the true sound of your sub to come through by negating resonance artifacts.

  • Dramatically reduces structural vibrations through walls, floors & ceilings.
  • Preserves the accuracy of the original audio track.
  • Tightens bass and increases low-end clarity.

Construction: The Auralex SubDude-II features a functionally inert 3/4", velour-covered, MDF platform supported by a 1" base layer of sturdy Auralex Platfoam that is an effective isolation boundary to decouple the subwoofer from the floor underneath. This combination of materials dramatically diminishes structural vibrations and resonances, resulting in reduced coloration, tighter bass and a perceived extension of the subwoofer's low-frequency response.

Compatibility: The Auralex SubDude-II is great for home theater & hi-fi small- to medium-size subwoofers weighing up to 200lbs. The SubDude-II measures 15.0625" (w) x 1.8125" (h) x 15.0625" (d).

The Auralex Guarantee: All Auralex foam products have been specially engineered for maximum acoustical performance, increased longevity, flame retardancy, and great looking aesthetics.

Used to de-couple a 12" subwoofer from my wood floor. [ James  Jun 10, 2017 ]
I chose to use this because I have hard floors and my sub kept moving around. I tried the spike and they kept it in place but caused the sub to audibly vibrate and the sound wasn't as good. So I'm hoping with this my problem will be solved and my sound quality will stay intact. [ Daron  May 30, 2017 ]

3 questions already asked

I have not used their turntable pad but my guess would be that the subwoofer pad is built to handle more weight. I can tell you that it made a big difference in my system. When watching movies the windows, and other things, would sometimes rattle. After putting the sub on the pad all the energy is now going to sound. The lows fill the entire soundstage. I recommend giving it a try. Good luck. [ Charles  Aug 24, 2018 ]
Hey Brian, I currently have the SubDude-II which measures 15" square. It works really well with my Audioengine S8 Subwoofer. However, I listen to mostly classical and jazz and rarely drive the sub hard. Your Def Tech Supercube measures 14.25 square. So, it should fit fine although a little bit tight. However, the purpose of the SubDude, at least in my mind, is to elevate the sub off the carpet and provide a uniform surface density for the subwoofer to play off of so as to clarify and tighten the bass content of the music . Obviously, the SubDude HT would be a lot larger but I don't think it would be significantly better at achieving the purposes I mentioned. So, I would start with the smaller SubDude-II and see how it sounds with your setup. If not, you always have the option of returning it to Crutchfield for a refund or exchange for the larger one. One last thought is to perhaps experiment with where you have your sub placed. Moving it one way or the other around your listening area can have great effect on eliminating resonance. Good luck! [ Robert  Jun 25, 2017 ]
The Sub Dude-II should work fine. [ Michael  Jun 25, 2017 ]
Hi Brian, I have a very similar size sub and I purchased the Auralex SubDude-II and it fits on this perfectly. The Pad is slightly over 15 x 15 so it will fit your supercube. I can say that this pad did a great job stopping the issues I had prior with my sub on the floor then on a stand I built for it, the pad seems to work similar to that of what dyno-mat would do in a car and takes out ratle and other similar issues. The product code for the Pad is 927SBDDE2. Thank you [ Jason  Jun 25, 2017 ]
From what you describe about the shaking of walls and furniture, I'm a bit reluctant to say that the SubDudes will alleviate your problems. They work well for me but I don't play my music at ear-bleeding levels. What the will do, however, is allow your RELs to play as evenly and precisely as they were engineered. They elevate the subs off the floor to allow the bass sounds to radiate out rather than to get pushed down and stuck in the carpet or floor. So, given Crutchfield's wonderful return policy, give them a try and see what you think. Best of luck! [ Robert  Apr 21, 2017 ]
Yes you can, and it will tighten up the bass too. You can also try to pull the sub(s) away from the wall or corner, [ Michael  Apr 21, 2017 ]
Hi Paul...I have a REL t7i on Auralex SubDude-II which is on carpet. It's in a second floor apt. I believe it helps with the vibrations going to the first floor. I don't have any issues with wall/furniture shaking. I can definitely feel the low end in my home theater set-up when playing blu-rays but that's the way you want it to be...but not rattle the furniture. Your 2 t9i subs have more power than mine but I do think the isolation platforms will improve the shaking you're experiencing! [ LYNN  Apr 21, 2017 ]
I have a Polk 12" 150 watt sitting on mine in a carpeted room on the second floor of my home. It does a great job of dampening vibrations while providing excellent, driving lows. It's part of a 7.1 surround system connected to an Onkyo TX-NR 757 receiver. I've been quite pleased with the SubDude II. I say go for it. You never know until you try. Good luck! [ Robert  Apr 21, 2017 ]
I use this on my hardwood floor and it definitely helps send the sound out the speaker and not through the floors. My windows rattled before and now they don't, I would definitely recommend trying them. My experience has been good with using this under my sub! [ SEAN R  Apr 21, 2017 ]
