Abstract

See full text

Loudspeaker enclosures that support improved acoustic radiation efficiency at low audible frequencies without compromising acoustic radiation efficiency at mid and high audible frequencies. Embodiments include enclosures having a primary chamber and a secondary chamber acoustically coupled to the primary chamber via a passive radiator. The geometrical characteristics of the secondary chamber and the corresponding air plenum are tailored for enhanced efficiency at low frequencies.
