Fohhn Convertible Dispersion Technology

Cardioid on Command

Happy on and in front of the stage

Speakers with Fohhn Convertible Dispersion Technology (CDT) can be switched from vented to cardioid use. This is one of Fohhn's principles: sound should only go where it is wanted. Backward sound is effectively suppressed in cardioid mode, ensuring quiet on stage and precise forward dispersion. The musicians are happy about undisturbed monitoring, the sound engineer about clean microphone signals and the audience about rich, direct sound.

Noise reduction

Rock the crowd, not the neighbours

Another decisive advantage of cardioid operation is the minimization of unwanted sound dispersion beyond the concert area. This way, residents are protected simply and effectively and problems are avoided.
