not my idea or Ghettoblaster
This from Warren a buyer on Amazon
Warren 5.0 out of 5 stars Achieved what I wanted Reviewed in the United Kingdom on 18 March 2021 Style Name: squareVerified Purchase My lounge is on the first floor of a townhouse, and I've struggle to isolate my speakers from the suspended wooden floors which not only produces a bloomy overbearing resonate bass, but impacts my neighbours if I turn up my music. So I set out on an isolation mission, and some isolation spikes, two granite chopping boards snd a pack of this foam later and we're onto a winner. I've mounted the spikes on the bottom chopping board, then put five segments of this foam (located like the dots on the 5 dot side of a dice), and topped it by another granite chopping board. The result is a nice stable platform, and the foam is robust enough to ensure the speakers don't rock dangerously. Yes they will move slightly if you load them, but against other solutions I've tried this is by far the most stable. The good news is the speakers now sound transparent and punchy and if you head downstairs the ceilings are no longer resonating with bass to annoy others. So in summary, not cheap for a few bits of foam offcuts, but as it works I'll give it some latitude and recommend it. Now looking to do similar with the subwoofer. |

I bet they work to at least some degree
Would like to hear of a test between them and BR

I wonder who would tell the difference in a blind test?

I used similar washing machine feet under my speakers and they did do a great job compared with (spit) spikes. Mind you, look what my speakers did to them...  It took the very much more expensive Townshend Podiums to greatly better them. |

I use black ones under speakers and racks on a suspended wood floor boards covered with 12mm plywood and Amtico flooring |

Just ordered two packs of the square one’s ,I will try them on the two Rel subs if they don’t work they will be thick beer mats or coasters

Out pf curiosity I bought a set of these:  www.amazon.de/gp/product/B08MTM9GC1/ref=ppx_yo_dt_b_asin_title_o04_s02?ie=UTF8&psc=1They cost 27 Euros for 4, but I can't see them on Amazon UK. I stumbled upon them while looking for some thick, non-slip feet for a Sony Magnascale DRO console that I put on a stand at the back of a workbench and curiosity got the better of me even though I have Townshend units that sort of work on the same principle. I might use them if I ever get round to moving the crossover from below the Apex speakers to a separate housing and though two on each might provide some mechanical isolation. |

They would be dead easy to make and one could then match the spring strength with the weight to be supported.

My guess is that the Townshend is very similar, maybe identical, just black gaiters covering the springs

I seem to recall that jandl100 used these, or similar, at some point. |

I still have a set, bought from China. I see the price has gone up.
You can tune and balance them by removing springs. I seem to remember they're not perfectly quiet and squeak in their action.

Apparently you can change 'timbre' by removing or adding springs - does that mean I could change a modern violin to baroque??  There's a set on eBay that has "Sound full of thick warm"  |

Does the black sound better than white?

"I seem to recall that jandl100 used these, or similar, at some point."
Quite right. I had several sets of spring things. I still have some under my balanced mains transformer - intended to combat occasional low level transformer hum. Totally ineffective for that, but I can't be bothered to take them away.
They are one of those tweaks that I think sometimes makes a difference when placed under audio gear (amps, DACs, speakers), but I don't miss them at all when removed.
As for the black squares, I hope they don't do the low pass filter effect on an audio system's tonal balance that BR does in my system.

I seem to recall that we do hear similar things with BR, I thought you described the effect of removing them as making your system sound unpleasantly aggressive and forward? |

It's more subtle than that. They have a calming effect, for sure. Having done a lot of test listening in the past, I would say what they do is provide essential damping of the component they are under, together with isolation (the latter is done well by sorbothane, but not the former). This allows a wealth of inner detail to appear, not being obscured by the effects of vibrations and microphonics within the component.
Without BR, you lose that opening up and, if your system is playing hi-res, that's when edginess can appear, which I have done so much to control.
I think I've said that going hi-res opens up a can of worms and needs paying a lot more attention to mechanicals, as well as to RFI/EMI noise.
