EVO-3 Anti-resonance pad

The piezo effect is one of the basic properties of silicon. Vibration changes the voltage in the crystal lattice of silicon, and this voltage affects the flow of electrons in transistors. The effect of vibrations on the properties of transistors is small, almost imperceptible in everyday life. However, if we get into a listening studio environment with a quality listening set-up, the positive change in the sound with the EVO-3 pads is audible and clear.

As a technician, I was very skeptical during the first test. I heard the change in both transistor and tube amplifiers. I started to investigate how it is possible that the character of the sound of the amplifier changes due to vibrations. Over time, after a series of tests of various designs and materials, we developed an anti-vibration pad that really works. EVO-3 will highlight the space in music and highlight background details.

Let’s realize that human hearing is our most sensitive sense. That is why the volume of sound is given in logarithmic units of Decibel. Listening loudly at 100dB (one hundred decibels) is 10,000,000,000 (ten billion) times more powerful than at 1dB (one decibel). As audiophiles, we strive to push the technical limits of what is possible to hear as much detail in recordings as possible. The details are where the emotions, color, and space in music lie. The EVO-3 pushes the boundaries of detail in any audio setup. Tested on humans.

Speakers, by their very nature, create vibrations that travel through the air and reach our ears. Speakers are not headphones. Sound travels from the speaker throughout the space where we are listening. Acoustic energy travels at a speed of 345 m/s in the air. Acoustic waves reflect off the walls, ceiling and floor back into the space, where their energy is added or subtracted, and we hear their sum. The behavior of sound in a closed space is dealt with by acoustics, which is not the subject of this article. It is even more complicated, since we hear frequencies from 20Hz to 20kHz, where wavelengths range from 17m to 17mm.

The speaker membrane creates energy at various frequencies that travels through the space and adds up with reflections from the surrounding walls. Speakers are also affected by the energy they generate themselves. Vibrations from the environment are transmitted to them, which are delayed and of different sizes. By placing the speakers on the EVO-3 anti-vibration pads, they gain freedom in space and their sound performance becomes breath-taking.

Imagine the sea with waves. When you place a speaker in the sea, at the height of the waves, the waves will hit it and transfer their energy to it, they will shatter against it. If you place the same speaker on a boat, it will move in harmony with the waves and no energy will shatter against it. We can imagine the same thing with the propagation of sound, only air is 1000 times lighter than water and sound waves are much faster.
