PT-70

The PT-70 is an exceptionally powerful passive loudspeaker from the Perform series. Thanks to Fohhn CDT, it can be switched between cardioid and vented operation.
It can be used as the main sound system in clubs or at concerts or as nearfill for larger systems. It is also perfectly suitable for fixed installations in larger halls and stadiums. In combination with the PS-800 and PS-850 subs from the Perform series, the loudspeaker delivers excellent results.
To ensure optimal performance and operational safety, the PT-70 needs to be operated with Fohhn DSP amplifiers including the corresponding speaker presets.
