Focus Modular

DFM-400

Item number: 1342-XXXXX

DFM-400 is an active low-mid module with Fohhn Beam Steering technology. It can be flexibly combined with the high frequency modules DFM-100 / DFM-110. The new generation of our renowned Focus Modular system is now fully digitized and provides further developed Fohhn DSP and digital signal connections. Acoustically redesigned and equipped with even more powerful drivers, DFM delivers excellent, audiophile sound and best speech intelligibility. A high-quality and high-performance solution for larger conference rooms, theaters and even open-air concerts. And all of this with an enclosure that is just about 22 cm wide and can be flown straight and integrated seamlessly thanks to beam steering.
