Pin On Speakers Acoustic suspension was a more viable solution in older eras of loudspeaker design when one-way linear excursion could be around 5mm but modern designs aim for much larger excursions where high compliance suspensions become impractical. Specifically an aperiodic loudspeaker enclosure design can be looked at either as a ported enclosure that has resistance in the port or a sealed box that leaks. 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. An aperiodic port design is basically a leaky sealed cabinet which uses ports filled with foam that allows better bass response from a smaller cabinet compared to a sealed design but without the impedance peaks typical of a ported design.
