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?

Yes you are looking for even compression on all spring pods. You can use a level too you know.. Just like a fence post.. I woulds also make sure the top, bottom and springs are completely installed.. The springs can get hung in the bore a little..

I've used a few now, they are well made but they aren't perfect. :-) Step on them after you get your spring count right. Ear plugs in the springs too, Just a little nugget..

Thanks for the prompt response. Will look into it now. I've just removed one spring each from the rear footers and the gap looks even now.  Will do some manual compression after you have made the suggestion.

Right, I need some advice. No matter how I adjust the number of springs at all 4 footers, the gap between the top and bottom metal pieces of the two footers located at the front will not be the same as the two footers at the rear.

Current Setup

Two Nobsound footers at the front = 3 springs

Gap between top and bottom metal pieces = 3.5 mm

Two Nobsound footers at the rear = 2 springs

Gap between top and bottom metal pieces = 2 mm

 

Question : Is it better to add one more spring to both footers at the rear or remove one spring from the front footers? I have checked the levels with a spirit level. There is no issue with the leveling. The uneven gap is caused by uneven weight distribution of the component which is heavier at the front and lighter at the rear.

The gap between the metal pieces of the front footers will not be the same as the rear footers no matter how the adjustments are carried out.

I would appreciate any advice.

You looking for equal load distribution, the compression of the pod is what your trying to accomplish. Keep in mind it takes a couple days of playing to settle them in too. Never hurts to take notes and do a final adjustment and placement of the springs and pods. Remember use ear plugs to dampen the springs. Roll them up and put them inside the spring.. Itti Bitty stuff helps..

Alright, thanks for the advice again.  Will not rush it.
