Try again. Sub............I have Image 412/2's and found them rather bassy/one note boomy in our old house with old timber floors, using the spikes supplied. I bought a set of Herbie's Gliders and put them under the spikes.I'll never go back to the spikes only.Bass and mids cleaned up. Well the whole sound did.And I can easily pull the speakers out into the room for serious listening. Love them.Worth every penny. herbiesaudiolab.com/products/cone-spike-decoupling-glider?variant=12645103403063 I have a suspended kauri floor which I've tried to tame by putting my spiked speakers on a heavy granite slab. So sort of coupled.My logical brain says that the speaker should be rigidly coupled to its base, to allow the cones/diaphragm to vibrate without the cabinet moving. The Origin Live Astute just does my head in!  Introduce the HERBIE'S GLIDERS at not too much of a comparative cost (well, compared to new speakers, or room treatments), which DECOUPLE the speaker from the floor. So despite being a little skeptical, I thought I may as well give them a go, as another arsenal in my continual battle to try to improve my bass. And if they didn't work for me I could always offload them to sub  FIRST IMPRESSION?Well, no magical solution but the mid range was certainly clearer, more defined and forward sounding, no doubt due to a less boomy bass. Still can't get my head around why decoupling should be a benefit, but hey it seems to work.

All you need to do is tell yourself they are working and quite by magic they will start working

All you need to do is tell yourself they are working and quite by magic they will start working That sums up ALL that my scientific brain hates. Am I hearing an improvement only because I want to? My philosophical brain says does it really matter? If I think there's an improvement (even if there isn't in an absolute sense) then its an improvement TO ME, and so who cares. But I do have a little more faith in my impartiality, and can say that I'm not going to remove them any time soon!

Or, if you are of the mindset that something can't possibly make a difference, then you'll not want to find out if it does or not

There's some useful information at the ISOACOUSTICS webpage, the people who make the EISA award-winning & STEREOPHILE Product of the Year, 'GAIA' loudspeaker Isolator support feet.

That’s three recommendations for Herbie gliders - all members of DL forum.
MikeA, neilsan, and Citroen.
When I get my visa balance down a bit more will have to give them a try.

Remove the spikes and put carpet under the speakers. Don't be a retailers dream customer

Yeah im sort of in Grahams corner with this one: I tend to look at the underlying principle of these things i.e a spike on a metal plate with some sort of cushion onto another metal plate, and then figure out a way that I can duplicate that effect myself. Might jam jar lids and squash balls work as a trial system ?

Do I want to decouple my turntable? I'm tempted to try them under the Aura...

I recall reading somewhere that isolating speakers from floor with rubber was good. I'd like to find it again. My recent main speakers are on stands, second hand, seemed to suit them, approx 21cm high, but I added spikes through cheap carpet to concrete slab pan of the floor below, I'm up three storeys. Then temporarily small rubber pads top of stand to speaker. Neighbours to consider. Vibrations! ;=})) At the moment those are out of action. I'm using small ones on top of them (with their own foam or rubber feet) and a subwoofer. But I did use a hole saw and electric drill to cut out 'feet' from an old thick rubber piece I found. Maybe industrial squeegee. And have some left to cut more if I need to. That was quite firm stiff rubber. I spray painted them black. Just for any equipment. To raise height, for ventilation. But some decades back when sorbothane was popular, I bought 4 feet. They're presently under my Technics SL-6 turntable, next to the Sansui on its own feet. The shelf is two 30cm sections of MDF painted black, separated by a few mm hard foam layer.   I see now I need to clean the turntable, and have already adjusted the angle of that foot.
