  • 4S loudspeaker 
  • General Description

    The 4S is a lightweight 2-way passive loudspeaker using a neodymium LF driver and a coaxially mounted wide dispersion dome tweeter. The coaxial designed 4S 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 orientation.
     

    It can be used stand-alone or supplemented by different subwoofers from the xS-Series.
     

    The enclosure is injection moulded with an impact resistant black or white paint finish. The front of the loudspeaker cabinet is protected by a rigid metal grill backed by an acoustically transparent foam and incorporated into the rear panel are two M8 threaded inserts.
