The result is an audible deterioration in sound. We prevent partial vibrations with our Star Stabilizer membranes:
To do this, we apply precisely calculated embossings to the membrane, which stiffens it and thus guarantees uniform movement.
With the Star Stabilizer embossing, the membrane only moves in the intended direction and the sound remains free of any membrane interference.”
