Auralex II ISO Series Acoustic Decoupling 5,1 x 10,2 x 7,6 cm charcoal

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!

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.

I pondered on this purchase for a while, taking the reviews with a pinch. My obvious loss of bass control was apparent but not as bad as i believed. It was not as tight or controlled as the quality of the equipment should perform. This and with certain items in the room annoying vibrating at only 30% volume, it was not sonic heaven. Cue the Auralex. The transformation was instant, so much so the sub is now set at 80% without the slightest loss of control. I have also lowered the crossover. The bass is wonderfully tight and now so immersive. The main indicator is my wife used to notice the bass (negatively) but now not a peep despite there now being a heap more of it. The best £80 odd i have spent on my system.

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.

Ordered this to complement an impending purchase of a KRK 10s subwoofer for my home recording studio. Tried them on my 5.1 TV system and ---wow--the Bass completely melds as one into the audio like never before from my system. Previously, I could only turn the subwoofer up to level 2 (out of 10) and beyond this, the booming bass was just too much, rocked the house and detracted from the overall sound / experience. However, now i can turn the subwoofer way-up and just hear pure clean 'in-room' low-end that perfectly blends into the overall sound imagery, whilst materially limiting the boom / bass even in adjoining rooms.Such was the difference & improvement in the listening experience, this Dude is not going anywhere and I will just have to purchase another one to go with the KRK 10s!

Big difference. All the bass and layering, but without completely shaking the room. Reduces the vibrations but still letting you hear and feel it.

Solid! and works very well with my SVS SB-1000, If I went for a dual subwoofer setup I would certainly consider getting this again! foam really does reduce vibrations

Auralex 2 iso are great subwoofer isolated platforms they improveBass cleaner and tighter sound quality
