Abstract
A speaker assembly broadly comprising a housing, an input circuit, and a number of speakers. The housing includes a lower section configured to be positioned at least partially below a ground surface and an upper section extending upwards from the lower section. The input circuit receives audio signals from a sound system or other controller and actively or passively sends the audio signals to the speakers. The speakers include a low-range speaker positioned in the lower section of the housing and a relatively higher-range speaker positioned in the upper section. The speaker assembly is configured to be spaced from other speaker assemblies within a listening area with each speaker assembly generating low frequency soundwaves and relatively higher-frequency soundwaves. This reduces or eliminates out-of-phase crossover frequency wave cancellation effects within the listening area.
