Corner Cabinet

Wharfedale Corner Cabinet

Twin Loudspeaker with Frequency Separation. Designed to fit in the corner of a room the new Wharfedale corner cabinet loudspeaker is available in mahogany, or oak of any shade to order. Solid wood of the order of 1” thickness is employed for the exterior walls of the cabinet to achieve the requisite rigidity at low frequencies, and internal divisions are of thick material.

 A type WI2 unit with a cloth surround is used for low frequencies and a W10/CS unit for frequencies above 1,000 c/ s.
Frequency division is by means of a choke-capacity potential divider and a volume control employing a tapped choke is also provided. The high-frequency unit is at the top and is fitted with a diffuser for the forward radiation and a reflector that directs part of the back radiation through a triangular aperture in the top of the cabinet.

The back radiation from the lower unit is passed through a bass chamber to apertures at floor level.

We have heard one of these loudspeakers in operation; the multiple sound sources give an attractive spatial effect not found in single cone units mounted in a plane baffle. The bass response is smooth and unobtrusive, indicating the absence of any marked resonance. Without tone control the output in the upper middle register was prominent on some gramophone recordings but should be well suited to compensate for sideband cutting when the loudspeaker is used in conjunction with the average radio receiver. No trace of cabinet vibration could be detected with inputs of the order of 4 to 6 watts, representing the maximum acoustic output that could be tolerated in the average living room, having regard to the high flux density and efficiency of the units employed.

The separator unit, with cross-over at 1,000 c/s is available as a component for use with pairs of similar existing loudspeakers of 3 to 15 ohms impedance. The price is £3 15s.
