The 4S is a compact 2-way passive loudspeaker designed for professional audio applications where size and weight are critical. It features a 4-inch neodymium low-frequency driver with a coaxially mounted dome tweeter, providing a consistent and symmetrical dispersion pattern across both horizontal and vertical planes. The loudspeaker can be installed in either orientation, offering flexibility in system design.

Housed in a durable injection-moulded enclosure, the 4S is suitable for both indoor and outdoor environments with an IP34 rating for weather resistance. It is finished in either black or white paint and protected at the front by a robust metal grille lined with acoustically transparent foam.

Connection options include two NL4 sockets and a two-pole screw terminal block, with two M8 threaded inserts on the rear panel to support a range of mounting accessories. The 4S loudspeaker can be used as a standalone unit or paired with subwoofers from the xS-Series for enhanced low-frequency performance.

For projects requiring specific visual integration, the 4S is also available in the Special Colour (SC) option, allowing the enclosure and accessories to be finished in any RAL colour. The 4S loudspeaker offers a practical solution for high-quality, space-conscious audio installations.
