Phase Plug Technology
In any conventional speaker, the highest frequencies of audio
emanate from the area around the center of the cone and the lower
frequencies are produced by the area of the cone that is farther
from the center. In fact, the distance from the center at which a
sound wave will come off of a speaker cone is directly related to its
frequency. This helps explain why larger cone speakers are usually
capable of producing more bass.
Due to the shape of the conventional speaker cone, the higher
frequency sound waves tend to collide at a focal point. This causes
phase distortion and a loss in efficiency. As a result, accuracy and
transparency suffer. This also has detrimental effects on the realism
of the artificial sound environments created by today's high fidelity
digital audio and surround sound systems.
The phase plug pole piece extension improves driver performance
and clarity by deflecting delicate mid range audio out to the
listening environment thereby minimizing distortion producing
collisions.
