A speaker driver assembly for use in a speaker system is provided. The speaker driver assembly includes at least one centrally located high frequency sound driver and at least one mid-range frequency sound driver located to either side of the high frequency sound driver. A waveguide wall in the front of the speaker driver assembly directs the high frequency sound waves outwards from a centrally located opening. The waveguide wall has a plurality of small apertures in front of each mid-range frequency driver that are angled outwardly to allow mid-range sound waves to pass through the apertures while minimizing diffraction of high frequency sound waves passing by the apertures in order to generate a coherent sound wave front.
