Springs under turntable

Hello,
I spent last night adjusting the load on Feet of Silence footers and got it to work. I am excited to report that the footfall issue with my turntable is now gone which I couldn't accomplish using the Nobsound discs. The soundstage has opened up quite a lot as expected with better imaging, depth and clarity. The speaker disappeared much better than it did before. So I am happy with its performance but not completely satisfied with the price to performance ratio. I will continue listening to this set-up to see if there is any change in the performance over time.

I am not able to compare it with Nobsound discs because I was not able to get Nobsound springs work/eliminate footfall when placed under the turntable. However I have previously used Nobsound discs under heavier electronics and coming from that experience I can say that the Solid Tech feet of Silence footers do offer a much better performance. Better in terms of overall clarity, imaging and the speaker disappearing factor. As I mentioned before Solid Tech design being able to isolate in more than one dimension allowing smooth spring movement is expected to perform better but its price to performance ratio didn't impress me...

In my experience, the spring based isolator performance regardless of its design/price depends on the load sitting on top of it. Utmost care should be taken to ensure that every spring is compressed to 97/98% of its max load. Without that sound could appear to be bloated, bass heavy and veiled besides surfacing footfall issue for few turntables. For Nobsound discs, I measured a set of 3 discs each having one spring can cary a max of 18.5 lbs (approx). So this configuration needs to be loaded with almost 18 lbs to be able to get to the desired isolation point. Each spring/disc should need just a slight finger touch (not press) to get to the bottom and you should hear two discs touching each other. Any further load, you are not going to get the real isolation benefit. What I have stated here is purely my experience and I am not trying prove any theory or point...

@uberwaltz- What you are describing sounds like a less than optimal load situation with Nobsound springs. These springs are stiff and can take a lot of load. These discs can be used with one spring and hence your two spring per disc layout should work. You can refer to the following manual to see how a two spring layout could be implemented.

It is a Solid Tech manual but it works for Nobsound discs... Hope that helps.

Thanks.

@uberwaltz Try 3 Nobsound springs under the 401. 2 at front -the way I have them. Then 2 at back. Interesting upset in your result. Mine is the opposite with the mids projecting free of the speakers and the highs sparkling. Frankly, I thought my ESLs were tired in the treble. Until now. Lit up!

@mijostyn- I couldn't agree more on that 3hz isolation level. That is our target. However getting to that 3 hz natural frequency with compression springs needs a special focus on the load interms of weight & material that to me is the most difficult factor....That is where you are playing with balance, precision and the level of damping of the surface.
Thanks.

The big problem with just two springs is that it's now like a bike, only support on two 180 degree opposed points.
You really need three or four to be stable.
Try supporting your amp with two points.
You get the picture.
Now four pods means yes you can do it but it is very wobbly as I said even with them being compressed.

As for subwoofers the trick is to give the driver a perfectly solid enclosure with an infinite mass. Not so easy. Put your hand on your subwoofer enclosure while playing something bass heavy.

I have a pair of dual voice coil drivers firing opposed in a sealed cabinet (32mm or 1.26" thick MDF), with substantial bracing. The cabinet is not totally inert, however it is pretty decent. Though certainly no contest for my stand mounts with the steel plate lining it, also with cast iron braces, silicone filled hard drawn copper tubes and birch differential bracing. I have exposed the internals in my system page (the stand mounts, not the sub).

Both lifting the sub an inch, and isolating it at approx >4-5Hz makes for significantly less energy to be injected into the floor, the walls, and everything else.
It is an experiment worthy of the almost puny investment.
You may very well be surprised if you were to experience it for yourself?
