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

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

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 prevention7/10 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.

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.

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!

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

I didn't have too much of a problem with my compact subwoofer (an ELAC Debut S10.2) as I've managed to balance its volume against my stereo system, but I do have a suspended wooden floor, so I thought it might be worth getting an isolation platform. The Auralex II ISO Series is the perfect size for the ELAC subwoofer and it's reduced the amount of unwanted bass around the unit and allowed me to bring the volume up a touch. The quality of the bass has improved a little (a bit more detail perhaps) but I wouldn't say it's a 'night and day' type difference in sound quality. Others might notice a bigger improvement if starting with an integration issue and as always, YMMV.
