INTRODUCTION

The Niles HDLCRbx High-Deﬁnition, Left/Center/Right Channel Loudspeaker is expressly designed for superior sonic quality in front left-, center-, or front right-channel applications. It employs ad

vanced technology components that extract the subtle nuances in recorded music or the thunder

ous action sound in a movie. The HDLCRbx is the perfect choice wherever quality of sound is the most important consideration.

FEATURES AND BENEFITS

DUAL 5-1/4-INCH TCC WOOFERS WITH BUTYL-RUBBER SUSPENSION

The HDLCRbx features newly-developed woofer-cone material that combines injection-molded polypropylene 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 use of a butylrubber suspension offers substantial beneﬁts, including increased movement without mechanical limitations, weather resistance, and improved midrange damping for better detail and clarity.

BUMPBACK™ WOOFER MAGNETS

Niles engineers have utilized a unique woofer magnet construction, allowing far greater “throw” or voice-coil excursion. The result is a new level of deep bass performance.

1-INCH TETERON TRI-LAMINATE TWEETER

The HDLCRbx’s Teteron Tweeter employs a tri-laminate design consisting 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.

D.S.F.G. DIRECTED SOUND FIELD GEOMETRY® DELIVERS OPTIMUM PHASE RESPONSE TO LISTENERS AND COMPENSATES FOR HIGH LOUDSPEAKER PLACEMENT

The HDLCRbx employs Niles’ D.S.F.G. Directed Sound Field Geometry®. With D.S.F.G., the tweeter is offset from the center of the dual woofers. The resulting acoustic interaction between the woofers and the offset tweeter results in the ﬂattest frequency and phase response, approximately 15-degrees off-axis from the tweeter. This gives optimum performance to a seated listener, even if the loudspeaker is mounted above or below a TV or screen.

ACOUSTIC FINE TUNING

The HDLCRbx includes acoustic ﬁne-tuning controls on the rear panel. These controls enable optimization of the high frequencies and dialog with 3 dB of Treble Cut and 3 dB of Dialog Enhancement.

D.S.F.G. DIRECTED SOUND FIELD GEOMETRY® DEFEAT

The HDLCRbx includes a rear-panel control that enables the installer to deactivate the D.S.F.G. Directed Sound Field Geometry

in certain applications. For example, when the loudspeaker is installed at ear level behind a perforated screen, the loudspeaker’s response can be improved with D.S.F.G. defeated.

NILES’ HD HIGH-DEFINITION VOICE MATCHING

Ensures compatibility with other Niles HD High-Deﬁnition in-wall, on-wall, and ceiling-mount models to accommodate a wide range of system designs.

DOLBY® DIGITAL READY

The HDLCRbx is speciﬁcally designed for Home Theater Sound. This model exceeds the speciﬁcations set forth by Dolby Laboratories for the accurate reproduction of Dolby Digital-Encoded Sources.

INSTALLATION CONSIDERATIONS

RECOMMENDED AMPLIFIER POWER

For satisfactory performance, we recommend using a surround ampliﬁer with a power rating of 10 to 150 watts. Curiously, most loudspeakers are not damaged by large ampliﬁers, but rather by small ampliﬁers. If your system is playing loud music, a small ampliﬁer will run out of power very quickly and can create damaging “clipping” distortions. A more powerful ampliﬁer will play at the same volume without distorting. See OPERATION on page 10 for more information about ampliﬁer clipping distortion.

LOUDSPEAKER WIRE

Use 2-conductor loudspeaker wire when connecting loudspeakers to your receiver or ampliﬁer. For most applications, we recommend using 16- or 18-gauge wire. For wiring runs longer than 80 feet, we recommend 14-gauge wire. The HDLCRbx’s gold-plated, ﬁve-way binding posts will accommo

date up to 12-gauge wire directly. Larger sizes can be accommodated via pin connectors.

NOTE: THE HDLCRBX FEATURES GOLD-PLATED, FIVE-WAY BINDING POSTS THAT CAN BE CONNECTED IN SEVERAL DIFFERENT WAYS (E.G., BANANA PLUGS, SPADE TERMINALS, AND DIRECT WIRING).

When running wire inside walls or ceilings, use special jacketed cable (CL-2 or CL-3) to protect the wire and for ﬁre prevention. In some areas, conduit is also required. For a trouble-free installation, low-voltage wire such as loudspeaker wire must be run in accordance with the National Electri

cal Code and any applicable provisions of the local building code. If you are unsure of the correct installation techniques, wire jacket, or type of conduit to use, consult a professional audio/video installer, building contractor, or the local building and inspection department.

TECH TIP

Wire size is expressed by its AWG (American Wire Gauge) number – the lower the number, the larger the wire. For example, 12 AWG is physically larger than 14 AWG.
