Why Choose Ported Enclosures? As their name suggests, ported speaker enclosures are ported. Therefore, they are open to the environment and allow sound to escape and enter the enclosure. A ported enclosure is designed with internal pathways and acoustic damping that effectively inverse the polarity of the rearward sound waves. Therefore, upon leaving the enclosure, the rear sound waves now interact constructively, rather than destructively, with the front sound waves. In other words, the problematic phase cancellation has been solved. This results in greater efficiency ratings and less reliance on amplifier gain.
