These did a great job of isolating my subwoofers from the floor. Before I purchased them, I had a lot of rattling in the room but after putting them under the subs, all I heard was the clear thunderous bass in movies.

Pros: Excellent isolation for subwoofers. Greatly improve low frequency clarity.

Cons: None

Ronald from Fresno, CA on 8/5/2018

Verified employee purchase (What's this?)

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.

Pros: Does a decent job decoupling the sub from the floor, which is good for me since my apartment is upstairs. Does a good job cleaning up th bass, and a really good with downward firing subwoofer.

Cons: Cost, if it was $20 less I'd give it 5 stars!

Great Bang for the Buck

Jim from Byrnes Mill, MO on 2/17/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

I cannot believe the sonic difference these things made in my rig. We have a concrete basement floor with killer padding and carpet, but I've broken at least a dozen wine glasses by bouncing them out of the glass racks... on the other side of the basement. I run a Yamaha RX-A2060 with an Emotiva seven channel amp on the mains, with a pair of Klipsch Sub 12's and three Polk Monitor 70 Series II for L/R/C. The Atmos speakers are driven by the AVR. The bottom is noticeably tighter, punchier and seems to be more effortless. In fact, I reduced the gain on both subs a bit. Any coloration and muddyness have disappeared, as well. Best money I have ever spent on my theater system at this price point, and I'll be ordering two more for my studio, too.

Pros: Aesthetically pleasing, perfect size, works as advertised.

Cons: None.

THE AURALEX SUBDUDA-HT WORKS VERY WELL, ESPECIALLY IF YOUR SUBWOOFER IS DOWNWARD FIRING AS MY IS AND IT SITS ON A HARDWOOD FLOOR. IT KEEPS THE BASS TIGHTER AND HELPS WHEN THE VOLUME IS UP. I WOULD HAVE TO TURN THE VOLUME UP AND DOWN AND NO LONGER HAVE TO DO THAT. IT WORKS AS ADVERTISED AND IT REALLY HELPS.

Great item! I was having issues with my large Polk Audio subwoofer vibrating items on wall behind it and causing irritating noises.The Auralex pad completely absorbed all vibrations from the sub, and I now have a much cleaner and clearer bass sound coming from the sub!

Features

Subwoofer Isolation Platform: The Auralex SubDude-HT is a low-profile subwoofer isolation platform and is perfect for small subwoofers in home theaters and hi-fi systems. The SubDude-HT 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-HT 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-HT 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-HT is great for home theater & hi-fi large-size subwoofers weighing up to 300lbs. The SubDude-HT measures 18.0625" (w) x 1.8125" (h) x 22.0625" (d).

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

Will my Sunfire SDS 12 rattle off the isolator? It jumps around on my wood floor.
[ Dalton  Aug 25, 2018 ]

No. It decouples the sub from the floor and absorbs a lot of vibrations that may travel through your hard wood floors. It does it's job for my HSU

I have a 2 sub system we use to watch movies. Both subs have their original feet with isolation pads. However, with the SubDude we notice markedly less vibration from the home's structure and better enjoy THX volume of movies.
[ Richard  Aug 17, 2018 ]
A
Honestly, it depends on how hard you drive your subwoofer. If you drive it hard or have it close to a wall, then yes.
[ CLEVELAND  Aug 16, 2018 ]
A
Absolutely!
[ ThomasZ  Aug 16, 2018 ]
A
Yes! They hold up well even with heavy subwoofers. They make the sound from the subs sound realistic and deep. You can't go wrong with the Subdude.
[ GERARD  Aug 16, 2018 ]
A
I've been using these for years and I think they work better than isolation pads or feet. I would buy it for your Supercube but this is the larger Subdude and you may be able to fit your sub on the regular one. I would measure and check that before ordering.
[ Justin  Aug 16, 2018 ]
Q
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!

[ JAMES  Aug 25, 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.

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.

Q
Does this work to reduce vibrations for home speakers as well as subwoofers?
[ Adam  Oct 22, 2017 ]

A
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 ]
A
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 ]
A
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.
