The crossover assembly includes a tweeter filter assembly and a woofer filter assembly. The tweeter filter assembly includes a tweeter filter housing, a tweeter filter mounted in the tweeter filter housing, an input port, an output port and a first mechanical connector. The woofer filter assembly includes a woofer filter housing, a woofer filter mounted in the woofer filter housing, an input port, an output port and a second mechanical connector. The tweeter and woofer filter assemblies are dockable by interengaging the first and second mechanical connectors and are separable by disengaging the first and second mechanical connectors.

Abstract: An office furniture system of free standing furniture elements which can be linked to each other comprises a modular desk unit and a modular storage unit. The modular storage unit occupies the same floor footprint as a rectangular desk unit. The separate storage unit enhances the storage capacity of an office layout since the mounting of drawers and shelves are not limited by the desk unit configuration. The storage unit has compatible lay-in wiring trays, accepts compatible modular power components and accepts the same privacy partition panels and other accessories as are mounted to the desk units. When the desk unit and the storage unit are linked into an integrated office design, a continuous pathway is provided for the electrical, communication and data wiring required for the office system. Power cables are physically separated from the data and communication wires.
