INTRODUCTION

The Niles HDLCR High-Deﬁnition, Left/Center/Right Channel, In-Wall Loudspeaker is expressly
designed for superior sonic quality in front-, center-, or rear-channel applications. It employs
advanced technology components that extract the subtle nuances in recorded music or the thun-
derous action sound in a movie. The HDLCR is the perfect choice wherever quality of sound is the
most important consideration.

FEATURES AND BENEFITS

INJECTION-MOLDED TCC WOOFERS WITH BUTYL-

RUBBER SURROUND, LONG-THROW VOICE COIL/

MAGNET STRUCTURE, AND VENTED POLE PIECE

The HDLCR 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. A long-throw voice coil/magnet
structure ensures increased cone excursion to enhance low frequency response and dynamic
impact. Additionally, each 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.

1-INCH TETERON TRI-LAMINATE TWEETER HOUSED IN A

PRECISION ADJUSTMENT MECHANISM

The HDLCR’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. This advanced
tweeter is housed in a precision adjustment mechanism, which permits the tweeter to be ac-
curately positioned after installation for optimum performance and without the diffraction distortion
typical of traditional pivoting tweeters.

DIRECTED SOUND FIELD GEOMETRY™ (DSFG) DELIVERS

OPTIMUM PHASE RESPONSE TO LISTENERS AND COM-

PENSATES FOR HIGH SPEAKER PLACEMENT

The HDLCR employs Niles’ Directed Sound Field Geometry (DSFG). With DSFG, 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 loud-
speaker is mounted above a built-in TV.
