Tout cela n'est pas "donné"

Et l'explication du chef penseur n'est pas très rassurante:
 ""Air molecules are a barrier to sound waves, and inhibit their free travel from speaker to your ears. The Room Neutralizers, which are activated by the electromagnetic waves of your amplifier, allow sound waves to travel without impedance or attenuation. They keep sound in phase as it travels far from the speakers, and prevent high frequency roll off."

sans molécules d'air, sans atmosphère, ça va tout de suite marcher bien mieux.
