ABSTRACT:
A speaker cabinet of the type used in stereo systems. A horizontal wall partitions the interior of the cabinet into an upper portion within which is positioned a full range speaker member, and a lower portion within which is positioned a low range speaker member. A pair of laterally spaced ports are formed in the partition wall to allow sound emanating from the low range speaker to enter into the upper portion of the cabinet. A horn associated with the full range speaker is spaced apart therefrom, in non-attached relation thereto to define a space between the full range speaker and the horn. Sound from the low range speaker and from the full range speaker enters into the space between the full range speaker and the horn and mixes so that the sound emanating from the horn is a full-bodied sound characterized by minimal distortion and substantial absence of unpleasing sounds of the type associated with speakers of the prior art.
