ABSTRACT:
A coaxial loudspeaker system is described wherein the high frequency horn which lies within the lower frequency speaker or cone, is constructed to avoid the "shadow effect" wherein there is a large drop in the magnitude of the response of the low frequency speaker over a narrow frequency bandwidth due to diffraction effects caused by the presence of the horn. The horn is formed with a group of slots near its wide end, to provide an opening for the passage of lower frequency sounds into the axial region of the cone which would otherwise be blocked by the horn.
