High frequency horn

A loudspeaker horn that can be used in a coaxial speaker system, comprising:

• a main housing in the form of a horn with small and large ends and with walls primarily of sound reflective material;
• and
• a buffer lying at the large end of the horn and having walls of partially sound absorbing material, said buffer having a largely tear drop cross section to provide a rounded extreme end and sides at the large end of the horn, said buffer having surfaces substantially flush with the inner and outer surfaces of said main housing.

A loudspeaker horn comprising:

• a housing forming a horn with a narrow end portion for receiving sound and a wider mouth end portion for coupling the sound to the atmosphere, at least the mouth end portion of said horn having a largely rectangular cross section, with a cross-sectional width greater than its cross-sectional height, said housing forming walls at the inside of said horn including top and bottom main walls and also including opposite side walls spaced part by the width of the horn;
• said top and bottom main walls having highly sound reflective surfaces over most of the wall areas, but the inside corners where said main walls meet said side walls having sound absorbent surface areas extending along the length of the horn.

• said top and bottom main walls having highly sound reflective sufaces over most of the wall areas, but the corners where said main walls meet said side walls having sound absorbent surface areas, with said sound absorbent surface areas being of progressively greater width at locations progressively closer to the mouth end of the horn.

• said housing including walls of hard sound reflective material forming most of the inside surface of said horn, and forming corners where said walls meet, and said housing also includes strip-like areas of sound absorbent material fastened to said walls and lying in said corners.
