Has anyone heard of the term Aperiodic used with speaker cabinet design. It does have a vent in the rear panel of the enclosure but unlike a conventional vented design utilizing a Helmholtz resonator the vent. aperiodic loudspeaker design.
Aperiodic Loudspeaker Design, The impedance plot tells us what the cone motion is doing because the driver is a reciprocal network and motion on the secondary is reflected back into the primary as a voltage. A loudspeaker enclosure or loudspeaker cabinet is an enclosure often rectangular box-shaped in which speaker drivers eg loudspeakers and tweeters and associated electronic hardware such as crossover circuits and in some cases power amplifiers are mountedEnclosures may range in design from simple homemade DIY rectangular particleboard boxes to very complex. It sounds like you essentially wrap the driver with some sort of breathable fibrous membrane in the right thickness of course and.
