Wool Felt Footers?


I am curious whether any of you have tried using thick wool felt as footers, or as a vibration damping layer under equipment.  I view the material as performing a similar function as the Owens Corning 703/704 material that AV Room Services, Ltd. uses in their Equipment Vibration Protectors, or EVP footers (link).

According to AI:

"Yes, wool felt is an effective vibration damping material due to its unique structure and properties. It absorbs vibrations, reduces noise, and is suitable for various applications, including automotive and industrial uses. 

Wool felt’s porous structure and the way its fibers interlock allow it to absorb and dissipate vibration energy, converting it into heat.  The same properties that make it a good vibration damper also make it a good sound insulator. It can effectively reduce noise transmission..."

What I have tried so far is placing a one-inch thick layer of dense wool felt completely beneath the platforms that are supporting a heavy Aries Cerat Helene DAC (90+ lbs. including the brass damping discs on the top) .  The one-inch thick felt is attached to and positioned directly beneath a Zoethecus Z-slab (constrained layer platform), which supports a Black Diamond Racing shelf (carbon fiber) on which the Helene DAC sits.  Right now the footers supporting the DAC are platinum silicone hemispheres but I may try other options, including footers made from the one-inch thick felt.

Experimenting with Structures to support Audio Equipment can bring very good improvements for tidying up the sound.

The entirety of the Structure for the System and then working with support for individual devices will be the best way forward.

My own experiences are to be open minded and limited in the methods used, systems are set up in environments that are unique and not duplicated at other locations.

One mans reject in one environment can very easily become in another environment the most impressive to have been used.

If Natural Materials are capturing your Interest, I am not without Cork in a variety of thicknesses, nearly all interfaces are using Cork Solely as the separator or as part of an assembly used a separator.

Cork + Felt might be a winner?  

Ultra Transparent being produced is a very particular preference for a certain selection of individuals, most want a sense of having moved towards being transparent with a end sound, but are also very secure in their acceptance of a colour influence being present.

It is each to their own, when added Color is to be cut off.

There are a selection of Colourations that can be produced, but to keep it simplified I will refer to it as follows:

1, A detectable hint of Weight that is at the base of the notes and vocals, which is able to influence the tonal character that is noticeable for being present. 

2, A noticeable weight that underpins notes and vocals, which is influencing the tonal character to a point that is very noticeable for being present. 

3, A weight is present and undeniably attached to notes and vocals, which is influencing the tonal character and frequency range to a point that it is present and can be overwhelming.

Creating a Supporting Structure for the System and then working with support for individual devices will enable systems in use using the above influences, to be tuned to meet ones personal preference for how a Color is able to influence the end sound produced. Creating this influence is not limited to to the Structure Only, the structure when working for the individual will be the gathering of the reigns, and created influences will become gathered/ tidied up. 

Measurements of a materials interaction with transferred energy are a guide only, but experiencing options in use, supplies a tremendous opportunity to attain the optimised support set up for the individual.   

I know from past experiences that both Squash Ball Hemispheres and Hockey Pucks have been used by individuals within the Plinth for a TT and to mount the Plinth on.

Balls and Pucks having spent their energy are also recommended and should not have a cost. Speak to a Local Sports Centre where Squash is played or the local Hockey Club and either will happily assist with collecting the Spent Energy Balls or Pucks.

Another Cheap version to be effective as a footer is in the Link described in Item 7& 8 in the List with directions. The same can be achieved using a Spoon with Handle removed and the Steel Ball, there are plenty of these simple design footers in use, but unfortunately there are large and unnecessary price tags for the items. .
