D&B Audiotechnik Z1615.000 4S 4-Inch Passive Loudspeaker

The 4S is a lightweight 2-way passive loudspeaker housing a neodymium LF driver and coaxially mounted wide dispersion dome tweeter. It employs a 4” driver in a highly compact sealed enclosure and offers a symmetrical dispersion pattern in the horizontal and vertical plane while the cabinet may be mounted in either attitude. The 4S can be used stand-alone or supplemented by different subwoofers from the xS-Series. The enclosure is injection moulded with an impact and weather resistant (IP34 rating) black or white paint finish. The front of the loudspeaker cabinet is protected by a rigid metal grill backed by an acoustically transparent foam. Incorporated into the rear panel are two M8 threaded inserts, two NL4 connectors and a two pole screw terminal block. The loudspeaker cabinet and most accessories are also available with the Special Colour (SC) option that can be executed in all RAL colours.

Sea water resistant (SWR): This option is suitable for outdoor use, especially in wet and acid or salty environments. WR cabinets are equipped with a recessed connector panel including a Faston type connector (2 x 6.3 mm, female). A cover plate which accepts single or dual PG cable glands (Type PG13.5 for cable diameters from 6 - 12 mm) is enclosed.
