INTRODUCTION

Niles CM6HDfx High-Definition, Side/Rear Channel Effects, Ceiling Mounted Loudspeakers are expressly designed for superior sonic quality. They employ advanced technology components that extract the subtle nuances in recorded music or the thunderous action sound in a movie. They are perfect for applications where in-wall or on-wall surround speakers are not practical. Moreover, these ceiling mount surround speakers are designed for applications where quality of sound is the most important consideration.

FEATURES AND BENEFITS

INJECTION-MOLDED TCC WOOFER WITH

BUTYL-RUBBER SURROUND

The CM6HDfx features a newly-developed cone material that combines injection-molded polypro- pylene with talc, carbon, and ceramic (TCC) stiffening agents. As a result, the cone offers extreme stiffness and light weight for accurate, dynamic response. Additionally, the woofer employs a vented pole-piece for increased bass linearity and a butyl-rubber surround for improved midrange damping and clarity, as well as moisture resistance.

DUAL 3/4” TRI-LAMINATE TETERON TWEETER DOMES WITH FLUID-COOLING AND ULTRA-WIDE DISPERSION FOR CLEAR AND DETAILED HIGH FREQUENCIES

Each tweeter’s tri-laminate design consists of an inner textile layer which forms the dome, a high damping layer to kill unwanted resonances, and an outside layer of urethane to add stiffness and prevent breakup modes. The result is a transparently clear, sweet, natural-sounding tweeter, which still maintains extended frequency response. The 20°-pivot angle also ensures optimum, detailed high-frequency coverage.

DIRECT/DIFFUSE SETTING

The DIRECT/DIFFUSE switch allows the installer to select different sound-field patterns for different applications. In the DIFFUSE mode, the tweeters are “out of phase,” producing a very natural- sounding diffuse surround effect. In the DIRECT mode, the tweeters are “in phase,” producing a more present (“in-your-face”) surround effect.

NOTE: BOTH LEFT AND RIGHT SPEAKERS MUST BE ORIENTED WITH THE “OUT-OF-PHASE” TWEETER (IDENTIFIED BY A GRAY DOT) SO THEY POINT IN THE SAME DIRECTION, RELATIVE TO THE LISTENER. SEE PLACEMENT DIAGRAMS STARTING ON PAGE 6 FOR RECOMMENDED PLACEMENTS AND SETTINGS.
