Abstract
A loudspeaker cabinet having at least one side wall defining a side wall perimeter; a front wall mounted to the at least one side wall along the side wall perimeter, the front wall having a front surface; wherein a central area of the front surface is positioned within the side wall perimeter, an extended area of the front surface extends beyond the side wall perimeter, and a portion of the extended area is configured to provide a gradual transition to open free space.
Claims21
A loudspeaker cabinet comprising:
- a plurality of side walls defining a side wall perimeter, the plurality of side walls comprising a first side wall and a second side wall;
- a front wall mounted to the first side wall along a first side wall edge and the second side wall along a second side wall edge, the first side wall edge being a vertical edge, and the second side wall edge being a horizontal edge, the front wall having a front surface;
- and
- an extended area extending outwardly with respect to the first side wall edge and the second side wall edge, the extended area being substantially coplanar with the front surface;
- wherein the front surface with comprises at least two speakers mounted along a vertical center axis of the cabinet such that each speaker is positioned within the side wall perimeter with a first distance in a first direction between a center of the corresponding speaker and the first side wall edge,
- wherein a portion of the extended area comprises at least one profile feature in the first direction, the front surface and the at least one profile feature forming a continuous surface, the at least one profile feature having a length based on the first distance enabling the portion of the extended area to provide a gradual transition to open free space to create a gradual air load transition on sound waves produced by the at least two speakers.

- a front wall mounted to the first side wall along a first side wall edge and the second side wall along a second side wall edge, the first side wall edge being a vertical edge, and the second side wall edge being a horizontal edge, the front wall having a front surface;
- and
- an extended area extending outwardly with respect to the first side wall edge and the second side wall edge, the extended area being substantially coplanar with the front surface;
- wherein the front surface comprises at least two speakers mounted along a vertical axis of the cabinet such that each speaker is positioned within the side wall perimeter with a first side wall distance in a first direction between a center of the corresponding speaker and the first side wall edge,
- and
- wherein a portion of the extended area comprises
- a first linear extension of the front surface in the first direction terminating in a first front surface edge, with at least one first profile feature extending from and forming a continuous surface with the first front surface edge, the at least one first profile feature having a length based on a first surface edge distance between the center of one of the at least two speakers and the first front surface edge enabling the at least one first profile feature to provide a gradual transition to open free space to create a gradual air load transition on sound waves produced by the at least two speakers.
