Abstract

There is disclosed a speaker system. An enclosure may have a plurality of walls that define a resonant cavity. The resonant cavity may be essentially air-tight except for a speaker opening and a port opening. A speaker may be installed within the resonant cavity so as to cover and seal the speaker opening. A multiply folded tube formed a tuned port may be disposed within the resonant cavity. The tuned port may have a first end coupled to the port opening and a second end open to the resonant cavity.
