Systems and methods for speaker assemblies with wide dispersion patterns are disclosed. In one embodiment, a speaker assembly includes at least two speaker drivers and a diffraction baffle affixed to each speaker driver, where each diffraction baffle includes a baffle face having a diffraction slot positioned over the driver and each diffraction baffle is affixed to and sealed to the driver, the area across each diffraction slot is less than the surface area of the driver, each diffraction slot provides a path for substantially all of the acoustic pressure waves produced by the speaker driver to propagate away from the driver and the acoustic pressure waves are within a frequency range determined by the characteristics of the driver, and the width of each diffraction slot in the horizontal direction is equal to the wavelength of a predetermined target frequency.
