TT Diffusor 8"

Universal size for 8" speakers
Dome diameter: 80 mm

As the frequency increases, the radiation of a loudspeaker is increasingly focused on its center. If the listener is in this beam, the sound is extremely harsh and biting; if one moves to the side of it, the sound becomes significantly darker and treble components are partially missing.
To reduce this behavior, a diffuser is used. This sits directly in the beam of the speaker and deflects the high frequencies very strongly, it breaks the "beam". This makes the sound much fuller and more balanced.
