Entreq Vibbeater Vibration Absorber
if you remember your basic Physics lessons you will know that you cannot get rid of energy but simply convert it into another form. This is a fundamental law of physic's and of course nature. We have choosen a route that converts un-wanted energy into heat, as this is the least harmful to our precious musical signal.
‘Vibb eaters’ consist largely of our own dedicated copper-based sand mixture with the addition of small quantities of, amongst other things , specific precious metals. The properties of this mixture offers very interesting characteristics, particularly in the areas of magnetic fields, field effects, as well as dealing with physical vibration & surface energy. When you place a ‘Vibb eater’ on top of your loudspeaker speaker or on top of your electronic equipment the vibrations and various magnetic fields that come from the box's are absorbed, then through the mechanical friction between the copper granular mixture the excess energy is converted into very low level heat.
It's easiest to experience first hand the effect Vibbeaters have on your speaker by simply placing one ( there are a number of different sizes & weights for different speaker or electronic's cabinets) on top of your speaker while music is playing through them. Placing your hand on the speaker you should find that it is now almost free from vibrations but If you then move your hand/fingers and touch the ‘Vibb eater’ you will sense a great deal of activity, especially near the very top of the Vibbeater.
Guess where all the energy has gone ?
Through its weight it gives further stability to the speaker cabinet itself.
The vibrations and fields that are generated in the speaker box are most intense at the top of the speaker where the energy cannot go any further. When placing a Vibb eater’ on top of the speaker you are in essence extending the length of the speaker box to a critical point outside of the cabinet. The key is that that energy is no longer a part of the speaker itself. The Vibbeaters then simply absorb the energy and transforms it in to heat.
The magnetic characteristics that make-up the ‘Vibb eaters’ granular mixture can have a very positive impact on the fields generated in and around the loudspeaker itself.
In summary the treble tones become cleaner and free from the overtone distortion's of a vibrating baffle. The bass becomes quicker, tighter and with a deeper more textured sound. Above all the sound picture is widened which should give you a more precise position in width, depth and altitude. Last but not least there should now be a flow and a calm in the sound.

ben voyons manquerait plus que ça coûte des clopinettes , ça ferait pas sérieux 
Mes peluches sont plus mignonnes et moins relou !
le mélèze oui 
c'est là que j'ai découvert . Je savais même pas que ça pouvait exister des trucs pareils
