Nobsound springs - load range


I want to try out the Nobsound springs as damping footers (mainly under my mono blocks and my streamer). I ordered a first set of them and now I wonder about the amount of springs to put in for different weights of equipment.I remember one post that said it works best when 50% compressed (was it @millercarbon?).

I measured the compression of the springs, it takes ~2.5 kg per spring to compress it to 50%. Based on 50% compression target, this yields the following sweet spot configurations (only stable ones, total equipment weight):
- 3 units, 3 springs each: 22.5 kg
- 4 units, 3 springs each (or 3 units, 4 springs each): 30 kg - 4 units, 4 springs each: 40 kg
- 3 units, 6 springs each: 45 kg
- 3 units, 7 springs each: 52.5 kg
- 4 units, 6 springs each: 60 kg
- 4 units, 7 springs each: 70 kgLoad can be considerably higher than expected (somewhere I read about 36kg, which is presumably for 4 units).

Any comments?What about ~10 kg streamer, seems to be too light to compress the springs enough? Does anyone have experience with Nobsound springs under light equipment like this?
Based on your experiences: Would you even dare to put an 80kg floor standing speaker on Nobsound springs?

I am like you, i dont know either...

It is just fun to create simple experiments...

Merry christmast to you....

Imagine now fine tuned  damped loaded speakers with springs asymmetrically compressed  under and over the speakers....

😉

At peanuts cost i will try it myself.... Thanks to the old mechanic who feed chickens all day long....😊

Millercarbon is right...

in my case for eaxample,because of the structure and particular resonance of the box speakers for example, the right amount of load damping must be fine tuned BY EARS, like the springs compressive force applied by the weight load on the springs themselves...

They are in my case then , an optimal weight load of concrete around 80 pounds over my speakers, which must be tuned BY EARS in an optimization process  in relation with the speakers densities and resonant geometry and  also in relation to the precise compressive force which could be optimally applied to damp the resonance of the speakers and not only isolate from the the external vibrations...

This fine tuning is an incremental process of listening experiments distributed on a week....I first fine tuned for  the  optimal load of  concrete for the speaker box without springs...

After that adding the springs under the speakers i ADDED some "light " load playing in an optimization process near around 20gram toward 100 grams...
