The two most common types of speaker enclosure are acoustic suspension (sometimes called pneumatic suspension) and bass reflex.In both cases, the tuning affects the lower end of the driver's response, but above a certain frequency, the driver itself becomes the dominant factor and the size of the enclosure and ports (if any) become irrelevant.
A loudspeaker enclosure based on the concept was proposed in October 1965 by Dr A.R. Bailey in Wireless World magazine, referencing a production version of an acoustic-line enclosure design from Radford Electronics Ltd. [16] The article postulated that energy from the rear of a driver unit could be essentially absorbed, without damping the cone ...
This enclosure type is very common, and provides more sound pressure level near the tuning frequency than a sealed enclosure of the same volume, although it actually has less low frequency output at frequencies well below the cut-off frequency, since the rolloff is steeper (24 dB/octave versus 12 dB/octave for a sealed enclosure).

An acoustic short circuit is a phenomenon in which sound waves interfere in such a way that both waves are canceled out.This occurs when the peak of one wave aligns with the trough of another, and the compressions and rarefactions of each wave neutralize each other. [1]
