Housed in a curvilinear enclosure of custom birch and poplar plywood, the P18 employs a purpose-designed 18″ LF Neodymium driver and 4″ diaphragm HF driver in a coaxial configuration.  The compact cabinet measures just 680mm x 579mm x 446mm, and can be deployed in vertical or horizontal (wedge monitor) configurations, with HF directivity set to match the specific application. The back plate holds two Speakon® connectors (plus one each on both sides) and a recessed switch to change the cabinet from 2-way passive to 2-way active mode. Installation versions are available in custom RAL colours (Passive only) and feature a fixed cloth-covered grille, universal rigging points on the sides and bottom of the cabinet and 2-core cable for audio input to ensure IP54 protection index. TIS versions feature touring handles and connectivity, with cloth-covered grilles.
