ION TW 1S Ionic Plasma Tweeters

The Acapella Tweeter ION TW 1S is a perfected and sophisticated loudspeaker chassis, whose exceptional performance and qualities can only be enjoyed completely if used properly.

It was designed to reproduce the harmonics of the music as detailed as possible. To reach this goal, a design with the smallest possible mass had to be developed. Relative to its function the Acapella ion tweeter has no mass! To carry out this project, a very unusual kind of design had to be created.

High voltage within the unit produces a constant arc. This arc is modulated with the musical signal (flame oscillates with the time of the music). This is the reason why the number of electrons within the arc varies. A larger or smaller amount of electrons requires similar space. Due to this variable need of space the surrounding air molecules have to dodge more or less quickly. This evasive action or bumping of the air molecules generates over-, resp. under pressure and, therefore, sound. In this way, the Acapella ion tweeter is able to reproduce sound without membrane and without mass.

Regarding transient capabilities and phase stiffness, the obtained sound quality cannot be realized by using conventional tweeters. Comparing the ion tweeter with other tweeter systems, its unobtrusive sound image will attract you. This kind of reproduction is to be attributed to the lack of harmonic and transient distortions.
