Art. No. 50231
Visaton DK121 - 8 Ohm
Characteristics and Sound Properties
Built-in horn speaker - low profile. Waterproof design with an impedance of 8 ohms. Housing made of black lacquered aluminium, horns made of polypropylene (PP). High IP protection class, high sound pressure and good voice reproduction. Ideal for inconspicuous installation due to the very compact dimensions, e.g. in vehicles. The potential equalisation connection is by means of an M6 grubscrew (including two screws, lock washer and shake-proof washer) on the rear of the housing. The connection is via a two-core, halogen-free silicone sheathed flexible cable (250 cm) with insulated flat pin terminals (4.8/0.8 and 2.8/0.8 mm).
