Low Frequency Systems and Enclosures

  • John Eargle


The vast majority of loudspeaker systems sold today make use of sealed or simple ported low frequency enclosures. The primary purpose of the enclosure is to act as a baffle, preventing back radiation of the driver from directly cancelling the front radiation. The enclosure may be sealed, in which case there is no interaction between the front and back of the driver; or it may be ported, in which case there may be significant beneficial interaction between front and back. (By way of terminology, ported systems are also referred to as phase inverting and bass reflex systems.)
