"ChannelFlow^® Technology" encompasses the phase inverter arrangement.

Phase inversion is a critical element of an acoustic system; the arrangement directly influences the output sound quality.

In the Bolzano Villetri™ acoustic systems the phase inverter is purposely located under the dynamic head within the pressure zone. This is executed in a form known in aerodynamics as a "pilot tube", simply meaning the aperture does not face vector streams, but instead receives only non-directed values - pressure which does not depend on direction.

The position and parameters of phase inversion have been designed to efficiently correspond to the inner cubature of the acoustic system.
