Midrange Coloration Caused by Resonant Scattering in Loudspeakers

One of the significant sources of midrange coloration in loudspeakers is the resonant scattering of the exterior sound field from ports, recesses, or horns. This paper discusses a computationally efficient model for such scattering, based on waveguide models for the acoustical elements (ports etc), and mutual radiation impedance model for their coupling to the sound field generated by the drivers. This allows rapid evaluation of the effect of port placement, suitable for numerical optimization of loudspeaker enclosure layoutus.
