Abstract

A ¼ reflex λ loudspeaker system (1) adapted to modern devices in which sound can be reproduced. The system comprises a speaker (3), a cabinet (5) accommodating the speaker, a reflex port (7) and a quarter-wavelength resonator tube (9) located outside the cabinet. The cabinet is provided with a first aperture (11a) communicating with the reflex port, while the speaker front (3a) of the speaker is provided in a second aperture (11b) of the cabinet, which aperture is in communication with the quarter-wavelength resonator tube.
