This invention is directed a sound system (100) that groups a midrange horn (102) with a HF horn (104) to increase the sound pressure levels while minimizing interference problems. The HF horn (104) may be coupled to at least two HF drivers (106, 108) where they sum or merge into a common throat (110) or wave-guide. The midrange horn (102) may be coaxially mounted with the higher frequency horn (104). The midrange horn (102) may be coupled to at least two midrange drivers (112, 114). And the midrange drivers (112, 114) may be mounted subtantially perpendicular to the HF drivers (106, 108). This configuration provides for smaller system sizes, than conventional mounting of the HF horn (104) adjacent to the mid frequency horn (102). By coaxially mounting the midrange (102) and HF horns (104), the off-axis interference (lobing) through the crossover region both in the horizontal and vertical planes may be minimized. This configuration produces increased sound pressure levels while minimizing acoustic crossover interference problems.
