Abstract
One or more embodiments of the present disclosure relate to a two-way loudspeaker design that forces a condensed geometry between low frequency (LF) and high frequency (HF) drivers and then 'floats' a midrange waveguide in front of the LF driver. This is a hybrid design meant to benefit from the close proximity of acoustic centers without introducing a central axis obstruction for the LF driver. In addition, the LF and HF waveguides and associated acoustic elements are used to redirect very low frequency energy not supported adequately by the LF waveguide to exit freely using other paths.
