Auralex II ISO Series Acoustic Decoupling 4,5 x 38 x 38 cm black/charcoal

I bought this with a pinch of scepticism wondering if it would actually work for me. My new subwoofer system had been rattling, shaking my bedroom floor and most importantly, disturbing my neighbours as well as anyone sleeping later in the night. After some brief testing by walking around the house with this in place, and my subwoofer blasting, I can confidently say it reduces leaking low frequencies and cleans up any subwoofer rattle. It works! I am now able to play my music, or play games, a little comfortably louder at night without the fear of keeping anyone awake because of the rattling. The quality of the product is alright, but it essentially is a bit of wood and some foam. It's a rather simple, but very effective product. The value of this is really depends on how you'd use it. If you're living in a flat/apartment and want to prevent complaints from your neighbours while effectively allowing you to increase the volume more, I'd say it's worth your money in the long run. It has quite a sleek look, I appreciate the simpleness of it. It fit under my desk perfectly and took up barely any space at all. Overall, I rate this product a 9/10. 10/10 for sound clean-up and leakage prevention 7/10 for pricing... again it's just a bit of wood and foam, but they claim they have a high density foam that isn't quite like other brands. Whether that's just marketing bs or not, I have no idea. But I don't want to test it out either because this still works for me.

I recently purchased a pair of Steljes NS3 desktop speakers, plus an Elac Debut 2.0 S10.2 Subwoofer to enhance the base response, and was initially hugely impressed with the overall sound, especially compared to the aging Logitech 2.1 setup they replaced. The S10.2 is a downward firing Sub with a 10” driver, and 200W Peak / 100W RMS amplifier; the problem I have is that I live in an older property with wooden floors. At moderately loud listening levels the floorboards would vibrate and the bass, especially when listening to an electronic music genre known as “Dark Ambient,” which is practically built on visceral, growling, sustained deep bass drones and textures, sounded boomy, bloated, and muddy. The NS3’s sit on a wooden desk/table, and I had placed them on a pair of Adam Hall SPADECO1 isolation pads, so I knew I needed to find a similar solution for the Sub. Initially everything I could find was made from the same type of “high density acoustic foam” as the Adam Halls, which certainly wouldn’t work for a downward firing Sub weighing nearly 30lbs, and I was seriously considering getting the kind of anti-vibration feet and dense rubber matting you would put under a washing machine to stop it bouncing ‘round the room on the spin cycle. LOL! Thankfully I eventually came across the Auralex SubDude-II, and it seemed like the ideal solution; it has a 0.75” thick MDF top-plate or platform to support your Sub, bonded to a 1” layer of their patented “Platfoam” to decouple the Sub from the surface it’s standing on. So, after positioning the S10.2 on the pad I immediately loaded up my favourite go-to tracks below to see what difference, if any(!), it made to the bass. JS Bach: “Toccata & Fugue in D Minor” played by Daniel Chorzempa in 1982. Ray Barbee: “The Mingle” from “Ray Barbee meets the Mattson 2.” Dave Brubeck: “Take Five” from “Time Out.” John Campbell: “Firin’ Line” from “Howlin’ Mercy.” The Comsat Angels: “The Cutting Edge” from “Chasing Shadows.” The English Chamber Orchestra’s 1971 recording of “The Ouverture” from Handel’s “Water Music” conducted by Raymond Leppard. Goldfrapp: “Ooh La” from “Supernature.” Iona: “Wisdom” from “Journey into the Morn.” Pink Floyd: “Money” from “Dark Side…” and the pulsing machine ambience from “Wish You Were Here’s” “Welcome to the Machine.” Chris Rea: “The Road to Hell Part II” from “The Road to Hell.” Tangerine Dream: The title track from the live double album “Poland.” Vangelis: The “Blade Runner” soundtrack. Chuck Van Zyl: “Europa” from “The Relic.” The effect of the pad was immediate and dramatic, and I can happily say it does exactly what it says on the box; “Creates a cleaner, more accurate low-frequency response,” “Decouple(s) (the) Subwoofer from its supporting surface,” and, “Diminishes structural vibrations.” Even with the volume cranked there are no more vibrating floorboards or booming, bloated and muddy bass. On the contrary, using the SubDude-II has resulted in bass that is tight, clean, and musical, something you wouldn’t really expect from a budget Sub costing less than £150, even one designed by Andrew Jones. A final thought; the cost of the SubDude-II was about 50% of what I paid for the Elac Subwoofer, which seems like complete overkill, but the difference in the overall sound of the system has been so dramatic that I consider it to be money very well spent indeed… 5 Stars!

The platform looks good and completely eliminated any additional vibrations, so had a notable improvement in sound quality. However, when bass tones got very low and loud, I noticed a sound not dissimilar from the vibration of the sub on the hardwood floor. I eventually narrowed it down to the sound of the foam moving slightly on the floor. In order to fix this, I ended up placing a flannel underneath the foam and now have no issues! Slight inconvenience, but I can no longer fault the product. I'd suggest a layer of fabric on the bottom to the manufacturer to eliminate this. For something costing £60, it seems a bit daft to have to buy a flannel to make it work as described.

Seems to tighten bass nicely which now performs with more energy. More clarity and range of bass. Looks nice and reduces floor resonance. Very happy and a very impactful upgrade for the price

First of all, I was expecting a few pieces of hard sponge glued together. It is actually a solid pedestal of "something" (assuming wood) covered in felt, with sponge legs all around the perimeter of the pedestal. It has a good weight to it: nice and solid. Regarding sound, I can't notice any difference. However, I can definitely notice the lack of sound "spread". I can use the subwoofer on a higher volume and the bass is directional from the subwoofer as opposed to vibrating the floor, the walls, and feeling the bass in all rooms in the house. The bass now feels much more localised, and this was my sole reason for purchasing this product. Very happy customer here.

Live in upstairs flats with wooden suspended floor so had a lot of overblown bass and vibration , saved up the money and purchased two ,one under each speaker and the change it made surprised me ,i bass is so much better behaved with better definition ,its a bit expensive but if you want Hifi to sound its best especially if you have floor issues i would say it well worth it

Looks premium but didn't see much improvement

Worked a treat, really nice improvement to my B&W Subwoofer. Stopped some of the reverberation and unwanted sonics I was getting. Very pleased.

This thing went from my bass shaking the whole house like an earthquake to me being able to play hip hop at 6am and nobody wakes up in the house

Exactement ce que je voulais produit haut de gamme

I purchased the Subdude as my last "hail Mary" before potentially being forced to replace my subwoofer with a higher-end sealed sub. I was experiencing ongoing bothersome bass issues with one of my home theatre setups. Hardwood floors with a Paradigm front firing, rear-ported sub, in the front corner of the room, resulting in boomy, uncontrolled bass. It was like this ugly wall of loose, muddy bass was consuming the whole front wall where my TV is, then reflecting to my seating position. Due to the room configuration, I do not have other options for placement of the sub. I started looking into room treatment options but there was no way I was going to install ugly wall mounted bass traps in a main floor family room, opposite a kitchen. I was wondering if the sub was transferring too much energy to the floor, which was then moving to the walls, causing additional resonance, generating additional sound waves, resulting in the terrible sound. I didn't have these issues when the sub was in my basement. I read hundreds of postings in different AV forums and countless reviews about the Subdude and how it will 'tighten up' bass, etc. I was thinking there's no way it can tighten up the bass but if it could potentially reduce vibrations, maybe there could be some value. Some 'haters' on the forums will say the subdude is useless and people's perception of the sound is strictly psychological. After reading a review from a professional publication, where they noted they always use an Aurelex Subdude when reviewing subwoofers, I decided to take a the plunge and gamble almost $90 on this product because I had nothing more to lose... it couldn't possibly make the sub sound worse. I installed the Subdude, actually upped the volume on my sub by 1 notch, then re-ran Audyssey room correction on my receiver, so the gain would be at -4. SVS recommends adjusting gain on the subwoofer so post calibration, it's set between -4 to -8, so I took their advice for my Paradigm sub. After manually adjusting speaker crossover settings in my receiver, I was ready to test. The sound quality difference was drastic. That ugly "wall" of bass I referred to earlier is completely gone. I am finally enjoying my sub in this room. The bass is now much cleaner and is not longer an annoying distraction. The bedroom above the sub also has less bass transfer via the walls but loud low frequency soundwaves will still easily penetrate through the floorboards. Although it may be cheaper to go to the hardware store, get a piece of wood, put some foam under it and built it yourself, I'm not sure you would get the same results, as this is firm acoustic foam and not something your furniture would be shipped in. Not all rooms are the equal. You'll have different furniture, flooring material and objects that affect sound reflection and absorption, so your results may be different but this Subdude solved my issue and saved me from potentially dropping $1000+ buying a new sub and I may have ended up with the exact same issues. I was hoping the Subdude would give a marginal improvement in sound. I was shocked how much difference it made in my situation. I'm now considering buying another Subdude for a different subwoofer. No regrets.

Every single review who said they help tremendously in apartment use were true. I don't know about those who say your neighbors won't hear anything at all, but they will help A LOT. I have a Shockwafe 9.2.4 and with those 2 10 in woofers this system pounds. Loud. It would literally make the wall shake to a point where my landlord told me if there's one more complaint I will have to move out. Since then I would never go above 1 on my bass settings. 1!! Now I finally got my Shockwafe bacl where it belongs. It can finally breathe. I still can't even come close to half of what it can handle but believe me the bass has been up to 3 all day volume 34 and no problems. I'll try going up to 4 soon, carefully of course. I haven't even talked about the actual bass itself. Those reviews are true as well. The bas does sound better. It sounds cleaner. Like it has better resolution. Best way I can explain it. It's like listening to Spotify then you get hifi headphones get a subscription to tidal and listen to a track in HiRes audio for the first time. It's still the same song you've heard a thousand times, but it's like you're hearing it for the first time. That's how these subdudes make my subs sound. I've used them for years but it's like I'm hearing them for the first time. Enjoy everyone

Perfect floor isolation for my sub...now the bass is very decent and correct...not overwhelming and the room does not vibrate with.
