Springs under turntable


I picked up a set of springs for $35 on Amazon. I intended to use them under a preamp but one thing led to another and I tried them under the turntable. Now, this is no mean feat. It’s a Garrard 401 in a 60pound 50mm slate plinth. The spring device is interesting. It’s sold under the Nobsound brand and is made up of two 45mm wide solid billets of aluminum endcaps with recesses to fit up to seven small springs. It’s very well made. You can add or remove springs depending on the weight distribution. I had to do this with a level and it only took a few minutes. They look good. I did not fit them for floor isolation as I have concrete. I played a few tracks before fitting, and played the same tracks after fitting. Improvement in bass definition, speed, air, inner detail, more space around instruments, nicer timbre and color. Pleasant surprise for little money.

My 2 set of springs(4 boxes under each speaker and 4 boxes on top of each speaker and those then directly under the load) are slightly differently compressed by a difference around 8 pounds( the weigh of the speakers+ the load for one set of boxes and only the load for the other set of boxes)... This fact is important....

Then the distribution of the resonance pattern inside the speakers are modified so much that it is possible to immediately hears the difference.... It is not a difference in the direction toward bass frequencies or high frequencies, even if they improved, instead more a direction toward better mids frequencies and better timbre tonality and a better imaging then....A naturalness impossible for me to get with only one set of boxes under the speakers even if the load is fine tuned for them....

I think no one has use the spring boxes in this way, then even with springs internal speakers resonance has a destructive effect that goes unnoticed .... I realize that after my experiment....Adding a second set of boxes decrease internal resonance interferences...


No cat or children allowed in my audio room, and even my wife give me the dust cleaner to use it myself here.....I think that only ghosts of great composers go trough my room but their spectral wandering pose no threat to the equilibrium of this tower of springs, plates, and slabs of concrete.....I will look for some load more dense and compact than concrete..... :)

Bars of gold bullion perhaps?

The real problem is subwoofers. You have a significant mass vibrating +- 2 cm.   Any vibration of the enclosure is distortion. This is for any speaker, if you feel the speaker vibrating you have distortion. Putting the speaker on springs will make it worse. Fixing a heavy mass to the top of the speaker will lower the frequency it vibrates at, get it low enough and it becomes insignificant.  This does nothing for cabinet resonance, vibrating panels. This is avoided by thoughtful design.

Not at all, petrified old heads will do.....

This is not my ears impressions...

I know my ears are biased.... :)

2 set of springs boxes instead of one with small difference in load on them will damp the internal resonance...It is very audible... Audible immediately in the naturalness of timbre.....
