Large subwoofer isolation platform
Our take on the Auralex SubDude-HT™ by Crutchfield's Dave Bar
The Auralex SubDude-HT isolation platform effectively decouples your subwoofer from the floor for cleaner, tighter bass.
Clean up your bass
Vibrating floors, walls, and ceilings add a lot of "mud" to the sound of your music and movie soundtracks. Placing an Auralex SubDude-HT under your subwoofer can clean up a boatload of those unwanted rattles, resonances, and sonic colorations by decoupling your sub from the floor.
This stylish sound-absorbing sandwich of velour-covered MDF and Auralex's proprietary sound isolation foam helps prevent sound coming from your sub from being transferred through the floor. You'll get cleaner, tighter bass, reduced coloration, and maybe even a thank you note from your downstairs neighbors!
The SubDude-HT's 18" x 22" platform dimension is sized perfectly for medium-to-large-sized subwoofers in home theaters, hi-fi systems, or recording studios.

I only gave it 4 stars because I feel it's overpriced, but it really works good! This is my 3rd but 1st I've used with a downward firing subwoofer. It does a great job cleaning up the sound, my best results so far! I highly recommend it, especially with a downward firing subwoofer.

Hardwood floors create a rattling noise in my living room and need to isolate the noise of my Klipsh subwoofer vibrations. [ DAVID Dec 03, 2017 ]
Good reviews. Recommended. [ SERGE Oct 01, 2017 ]
I already have one, and with the purchase of another sub, this works well. [ GERARD Aug 26, 2017 ]
The other was too small [ Shawn May 25, 2017 ]
House is rattling from sub woofer. [ Michael Apr 07, 2017 ]
My Kilpsch subwoofers are shaking my new house so badly that it sounds like the whole place is about to fall down around me! This product has excellent reviews on the internet, and I'm hoping these will help reduce or eliminate the rattling walls and ceiling. [ Christopher Feb 28, 2017 ]

4 questions already asked
2 answers We're placing two subwoofers in our basement TV/theater room. One will be on carpet (over the concrete floor), the other will be on vinyl plank (over the concrete floor). I'm already concerned that the subs will need to work harder for response below 25 Hz, but wondering if the Auralex Subdude-HT will help. Suggestions? Thanks! [ Todd Mar 12, 2018 ]
I am not sure sound wise...I purchased to protect my hardwood floors. With that said my JL Audio sub sounds amazing, but I couldn't tell you if there would be any difference with the sub sitting directly on the hardwood. Again, mine is just for floor protection. [ WILLIAM K Mar 12, 2018 ]
I think they are great! It reduces the vibration you would normally get on tile flooring or concrete. [ SERGE Mar 12, 2018 ]
We do not ship internationally; only to the U.S. and it's territories. https://www.crutchfield.com/Support/international.aspx For the U.S. version of the Velodyne SPL-1200II powered sub, the larger SubDude-HT would be required. [ Ryan Mar 08, 2018 ] Staff
The SubDude-HT measures 18.0625" (w) x 1.8125" (h) x 22.0625" (d). [ SERGE Dec 26, 2017 ]
Can't say it will for sure it depends on how the speaker stands on its base. [ DAVID Dec 24, 2017 ]
As long as it isn't too much larger than, 18" W x 22.25" D [ Ronald Dale Dec 24, 2017 ]
IT should work fine with speakers but has a large footprint specifically for subwoofers. I would recommend speaker isolation pads instead. https://www.crutchfield.com/p_927MOPADXL/Auralex-MoPAD-XL.html?tp=68326&omnews=13967619 [ Surjeet Oct 25, 2017 ]
Never thought to try that but my guess is that it would. You'll need to be careful as most floor standing speakers have spikes or feet that might be unstable on one of these. [ Dennis Oct 23, 2017 ]
That is an excellent question and my answer would be yes. I have a 2 story home with wooden floors on the upper level with two large sub woofers. I bought one of these to see how it worked before purchasing the 2nd one. They work great and eliminated all vibrations. I actually have one of my home speakers stacked on top of one of my sub woofers. I see no reason why it would not work the same for a home speaker placed directly on top. [ RANDY Oct 23, 2017 ]

Yes definitely. [ SERGE Oct 23, 2017 ]
Yes it will. The foot print of the pad will be large for most speakers. [ Richard Oct 23, 2017 ]
Yes it does [ John Oct 22, 2017 ]
It works perfect. Improves markedly. [ John Oct 22, 2017 ]
