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 using Nobsound springs under my monoblock amplifiers + stands (2" butcher block). Combined weight is 56 lbs. I use four Nobsound devices with three springs per device.

By eye test, the Nobsound devices compress 30%-40%. They definitely do not compress to 50%.

I believe three-spring Nobsound are too stiff for lighter weight components...preamps, disc players, DACs, etc. One could try using one or two springs per Nobsound device, but I believe this would make a Nobsound unstable. Perhaps someone has tried this and will report here.

I also use 2" diameter wave disc springs from McMaster-Carr. These are available in 25lb, 50lb, or 90lb loads. 25lb load version works well under lighter components.

Under my loudspeakers are Townshend Audio Speaker Platforms (since April 2020).

Would seven-spring Nobsound devices work under 80kg loudspeakers? Perhaps, but I might use five Nobsound devices (with fewer springs per device) for added support and stability. Given the choice, I’d opt for Townshend Speaker Platforms.
I use them, with full complement of springs, under only light pieces,
with great results.  And they also work on top of components, too.
More Flat Earth Science here! More foolishness! And Nobsound is a Ch*nese company seeing dollars to be made with some crazy tweaks! Next will be colored fuses!

So use nothing, you know of a better product? They are ALL bad?

Just wondering?

Can you help?

I certainly won't be sticking springs under my components! For aesthetic purposes I use hardwood cubes - no claim that they do anything to improve sonics!

Go to Springs Under Turntable thread.
Reading that first post all I could think, imagine how much better that guys system would sound if he put all that effort into trying springs and LISTENING to them instead of wasting it measuring dead weight.

Oh well. Maybe next time....?

Under large speakers, no problem. Depending on the size and shape you might want to put them on a platform ala Townshend Podiums for improved stability. My Moabs are plenty tall and narrow and no worries on springs here.

As for lighter stuff, the springs themselves are rather small and only 1/4" diameter. To use them one per corner, three to a component, would need to hot glue to the component or they would likely tip over. Or you could drill a 1/4" hole part way into MDF, which is what I did to make more footers using extra springs.

Nobsound springs really aren’t that good. Each spring is way too small, narrow, and stiff. What we really want is a spring like in Townshend Pods that when compressed is wider than it is tall. This gives stability. It also needs to provide freedom of movement in all planes. Nobsound really work great vertically but have a lot of lateral resistance. Another reason Townshend are a whole lot better.

If you experiment and listen instead of weighing and measuring you will notice the sound can be tuned to ear by simply removing one spring or even moving them around. Closer to corners increases effective stiffness, closer to center decreases, a difference you can see in how it bounces and hear when playing music. You can even remove or add a spring to just one at a time, and compensate (fine tune) by moving it around. Finally you can fine tune by adding weight, usually on top of the component. That’s what mahgister did, tuned his to perfection with tiny little adjustments just like these.

And all by ear.
You really need to think 360 for complete harmonic control, The Townshend, covers every plane, a lot better than single vertical support.

It has to be more like the little dog in the rear view, with his going around in circles. Bobble head.. engineering.. AY?

They sure look nice.. The Townshend, maybe the bobble head, too. A bobble head of Jane Mansfield. :-)

Must be jelly, jam don't move like that.
I went to a granite fabrication company and had them cut pieces that fit my components. Granite is a very dense natural stone that dissipates vibrations. I have placed very sensitive instruments in the component to dude the vibrations when playing music and there is none.
Granite rings like a bell. How you managed to get some and set it up and not notice, ... wait a minute. Dude the vibrations?!?! Nevermind. The dude abides.

Granite sounds terrible. 4 x Nobsound springs with 1 spring in each under my 13 pound phono amp work well.
