The aperiodically dampened loudspeaker system

Short, George Elliott III 21 November 2012 (has links)
The theory of the aperiodically damped loudspeaker system is derived and investigated in both the time and frequency domains. The advantages of the aperiodic configuration over sealed box loudspeaker systems are discussed. The aperiodically damped loudspeaker system is described by the parameters used for sealed box loudspeaker systems, with some additions. A real system is constructed which takes full advantage of aperiodic configuration, and its performance is compared with a sealed box system of the same dimensions. Complete derivations of the theory for both the sealed box and aperiodically damped systems are included, as well as methods for measuring all required parameters. / Master of Science
