Product description
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.
Amplifiers
The d&b 10D and D6 amplifiers are recommended to drive the 4S. The d&b D20, D80 and 30D can also be used.
