Abstract:
A loudspeaker capable of propagating coherent sound waves spherically in the manner of point source, comprising:a cylindrical housing having a lateral wall, a first end, and a second end; a relatively high frequency sound driver mounted in said first end of said housing, wherein said relatively high frequency driver is oriented to propagate sound away from said housing; and at least one other sound driver mounted within said housing below said relatively high frequency sound driver mounted within said housing such that said other sound driver divides said housing into an uppermost chamber located between said relatively high frequency driver and said other sound driver, and a lowermost chamber located below said other sound driver, wherein at least one other sound driver is adjacent to said relatively high frequency sound driver and is spaced apart from said relatively high frequency sound driver by a distance in the range of two and one half to two and three quarters of an inch, and said at least one other sound driver includes a relatively low frequency sound driver oriented to propagate sound downwardly into said lowermost chamber.
