Loudspeaker Acoustics is the study (either scientific or pseudo-scientific) of the behaviour of the loudspeaker and in particular the effort to create loudspeakers with good sound quality (either subjectively or objectively measured).

A number of approaches are used to address different aspects of sound quality, and to usefully model behaviour in different frequency ranges.

• Low frequency behaviour, relevent to woofer and subwoofer enclosures may be modelled using the lumped component model applied to acoustics.
