    I've got a pair of KEF R3 a week ago, and it has been standing on my desk so far. I want to get some speaker feet for it to absorb the vibrations of the sound. Could anyone recommend something that is not a small fortune (like the Isoacoustic Gaia series) and has a good size for the R3?

    Speaker dimensions without considering the grills and the connectors on the back (just the box itself):

    Height: 42cm
    Width:20cm
    Depth: 31.2cm

    So far, I've come across 2 options that I liked a lot, but are quite expensive for what they are, and another one that doesn't cost much but the width would be a bit too big.

    Rockville Iso-8: CAD75
    Auralex ProPAD: CAD195 (perfect size, but pricey)
    Isoacoustic Iso Pucks: CAD320 for 8 un (fits whatever size since these are pucks, but even pricier)


    I'm almost biting the bullet on the ProPAD, but would like to see if someone here has something to say first.

    Thanks :)

    Can you actually feel the vibrations in the desktop? You probably always will feel some, unless you go in for lab-grade isolation tables, which, in my humble opinion are only justified, in audioland, for oversensitive turntables. What I'm saying is do you really have a problem worth solving, worth spending money on?

    Is your desk too tidy? A bit more clutter might help with the reflections, which you will get even if you do isolate the speakers.

    I can't feel vibrations. I was going for a support pad just because I read that it improves overall sound quality.

    I have been using sorbothane for many years already, the official shelf life is 3 years but it seems to go much longer, you can either get them of Amazon or Isolate it! 30 Duro has the best decoupling effect but 50 Duro ones with urethane coat will have less staining effect on the surfaces they sit on.

    There is also sylomer but it is a lot more difficult to obtain but will last forever http://canadarubbergroup.com/loudspeaker-isolation-pads/

    Both would be my recommendations for a no BS solution.

    To me its a problem worth solving, my desk has an extra shelf which houses my speakers and my mic boom. The isolators really work to decouple the speakers from my mic. To boot, the decay of piano keys in the low mids are more defined.

    I have a bunch of the air conditioner pads referenced above but they are for much heavier objects and do not work well for things like speakers as much. Better than nothing I suppose. As for Sorbothane, it is good at damping vibrations but can leave a mark on wood. I had 4 circles on a nice dresser because of it. Put foil or plastic between it and the surface to pprevent damage.

    I use Herbies FAT DOTS under my small speakers that sit on wood stands. Works well. You could also try small blocks of wood under the speakers coupling to a more lossy wood like bamboo cutting boards and use the air con pads to decouple from desk surface. The wood and bamboo works well on components.

    I have had several situations, with speakers on a table or desk, where the sensation through the arms is irritating. If one can feel it like that, I'd say there's a fair chance it is affecting the sound even if not obviously. If you can't feel it, I'd say that you have well-made speakers, good solid desk, and no problem. At least no problem to spend money on. Was the guy who wrote what you read selling them?

    Try tweaks. Cheap tweaks. Stuff from around the house: soft stuff, hard stuff. Put it under the speakers.

    Also... don't rush. Get used to the speakers as they are. Until you know how they sound, the only changes you will hear are the ones your wallet tells you are real.

    +1 for the supply house pads @Gazny linked. I bought a bunch of them and use them under all sorts of equipment including my nearfield speakers on my desk.

    Sorbothane has chemicals that can stain surfaces, but there are Sorbothane products with protective coating. I have used this and it worked well for me: https://www.amazon.com/dp/B005I5RBK4/
    If you don't feel vibration transmitted to the desk, the effect will probably be minimal. You may get more benefit from raising the R3 with a stand such as IsoAcoustics ISO-200 to reduce early reflections off the desk.

    Bostik BlueTak putty. Pinch off a pea size ball under each corner. Speaker won't slide around on the shelf and it provides great isolation. About 7USD per pack which will do 4 speakers.
    Sorry I can't give you a more expensive solution, but this one works despite the low cost.

    Since you're in Canada, this is the Yorkville equivalent of the Auralex for half the price:

    If you want actual adjustability, then you may need something like this:

    Something else to consider is that all the fancy vibration damping doesn't do much good if the speakers are pointed at your chest instead of your ears. Put a couple boxes/books underneath first. This does two things: 1) it brings the speakers up to your face so the sound is actually reaching you directly (aim for tweeters roughly at ear level), 2) it reduces the smearing from desk bounce.

    Ended up with the Auralex. because it kinda felt like it was made for the R3 size wise. It was my last expensive ish purchase of the year, so what the heck. Change in sound was real, specially the bass. The Yorkville you've mentioned @Armaegis would be probably as good, I just wouldn't have the extra space because of the width. The link you've share is to the same store I bought the Auralex from. Now I can sit tight and wait another year until I blow cash into a Mcintosh MA252 or something as good.
