Abstract
Abstract A speaker is enclosed in furniture cabinets consisting of three units. The base cabinet, supported on legs, is a rectangular parallelepiped and accommodates a full range speaker. The top cabinet is pyramidal and accommodates a tweeter at one of its sides. An intermediate cabinet of smaller dimensions than either the base or top cabinets is interposed between the two and opens into both and accommodates a tweeter control.
