(54) Multi-speaker apparatus


(57) A multi-speaker apparatus (10) generates and transmits sound waves in all directions toward and away from a surface upon which the apparatus is installed or mounted. The multi-speaker apparatus includes a middle/high frequency sound range speaker (11) and a low frequency sound range speaker (70). The middle/high frequency sound range speaker and the low frequency sound range speaker are arranged relative to each other such that center axes thereof are aligned with an axis that is substantially perpendicular the surface upon which the apparatus is installed or mounted. A horn (18) and a cabinet (72) are arranged such that sounds generated from the middle/high frequency sound range speaker and the low frequency sound range speaker are emitted in all directions both toward and away from the surface upon which the apparatus is supported or mounted.
