Abstract
A method and system of improving frequency responses at lower frequencies from a loudspeaker includes simultaneously tuning a transmission line and a tuned port in the same system. The transmission line and the tuned ports are tuned to innate characteristics of the physical and electrical components within the loudspeaker. In one embodiment, an improved frequency response of a loudspeaker is achieved by tuning the transmission line to the frequency of the maximum excursion point of the loudspeakers. In another embodiment the transmission line is tuned to the resonance frequency of the loudspeaker having the tuned port.
