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....

Let's see, so we can put springs under the load, and also attach springs to the ceiling, with an adjustable rod attaching to the top of the load. Yes, a good weekend project, for sure.

I decided to give the Nobsound springs a try with my MC275 amplifiers. They were already resting on oak plywood bases (home made). I removed the feet and placed the bases on the springs and made sure it was level. Hooked everything back up, started my system and starting streaming the song "Along in Kyoto" by the group Air. First song and I heard details that I had never heard (maybe noticed) before.

I am trying to be skeptical about this, but the next album I streamed had what I can only describe as more depth. It was as if the sound field had depth below the floor. It’s a strange description, but as I was listening it was as if the floor dropped due to the sound field. It’s a weird sensation. It is really difficult to describe.

 

Instant success with first installation? What luck! I failed in my first attempt as the sound got worse when I first installed the Nobsounds. It took me about 5 days with arduous trials to get to the optimal spring configuration.

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

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>

Now take a piece of 1-1.5" all-thread and drill a hole in the top and the bottom of the speaker, countersink the holes top and bottom and use 6" x 1/2" washers. Now tighten to tone. You can make the cabinet sound like green concrete, if you tighten correctly.. Cost a couple of peanuts at least, all thread ain't cheap.100.00 should do it, used would work, 30-50.00 for 2 pieces of 60" all thread and make the washers.

Master M, you’ve done it again. :-)

Enjoy the holidays..
