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?

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..

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. :-)

In the spring and there are few different colors to. Technicolor. :-)

I'm at 390 lbs before a 2" base a 2" bronze cap (optional) and a rear cabinet modification.

Hovering at 500 lbs. I'm going with pods in three spots. The main speakers and the  TT stand. Air Ride is sure looking good.. :-)

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..

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..

No I sprayed 50 springs with Flex Seal and then used ear plugs inside the springs. It made quit a bit of difference.. It actually works perfect for lighter stuff like turntables, amps.. Speakers I notice it a lot less. The springs do it for the speakers alone. I load some gear with springs and a block of wood on top too. I load it in a slot between 2 3/4" pieces of 13 ply birch. Tinkering..

OP now you have tried ear plugs. NOW take the upper and lower portion along with the springs, and put the pocket side down. Spray everything with aerosol Flex Seal, reinstall your gummy puffers (ear plugs) in the springs and assemble.. 

Try that. Suspension 101. :-) Added another 6-8.00 usd for great dampening on your vibration and accumulator (shock) control.. 

I'm working on a budget pneumatic (air ride) system. :-)
