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.

Black Kevlar Woofers

The strength of Kevlar helps the cone retain its shape at very high energy levels and its low mass assures quick, accurate response. The cone's woven surface delivers smooth, uncolored mids. The kapton voice coil former and butyl rubber surround mean these woofers are designed

for years of consistent, reliable audio enjoyment.

Clamp-Ring Mounting

Our rectangular in-wall models utilize a clamp-ring mounting system which maximizes clamping surface. By distributing the clamping force over a larger surface area, the pressure on your sheet rock is reduced while the overall mounting strength is increased. The mounting ring comes pre-assembled to the speaker frame dramatically reducing installation time.

Pivoting Textile Soft Dome Tweeters

In our experience with various tweeter diaphragm materials, we have determined that the textile soft dome most consistently delivers natural, uncolored high

frequency audio. Ferro Fluid lubricates and cools the voice coil enabling high power handling. The pivoting feature allows the high frequency audio to be directed toward the main listening area. High frequency audio radiates from any speaker like the beam of a flashlight. This makes it necessary to aim the tweeter at the listening position to experience the full efficiency and detail that the speaker system is capable of delivering. These features work together to produce a seamless, transparent sound stage.

IR Receiver Knockouts

The 6 ½" and 8" rectangular in-wall speakers feature a mounting

provision for a remote control signal receiver behind the speaker

grille. This allows discrete integration with an infrared receiver/repeater system. These systems work with your standard IR

remote controls to allow command of your entire system from any equipped room in your house.
