DK 121 - 8 Ohm

Art. No. 50231

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, maximum fastening torque 2 Nm) on the rear of the housing. The connection is via a two-core flexible cable (250 cm) with insulated flat pin terminals (4.8/0.8 and 2.8/0.8 mm).
