A universal design procedure has been developed for enhancing the low-frequency response of loudspeakers ranging from handset loudspeakers to large subwoofers. The procedure attempts to find the optimal parameters of a vented-box system on the basis of the vibration-absorber theory. Simulations and experiments were used to validate the optimal design. Design charts and constrained optimization facilitate the design of the acoustic enclosure. Although limitations do not allow for accurate prediction of responses below 100 Hz, the comparison between closed- and vented-box performance correlates well with the desired bass extension.
