Introduction
The HD or High Definition group of Niles Home Theater Loudspeakers offers speakers
expressly designed for superior sonic quality. They employ advanced technology compo-
nents designed to extract the subtle nuances in recorded music or the thunderous action in a
movie. They are perfect anywhere that quality of sound is the most important consideration.
Features and Benefits
Dolby Digital
®
Ready
BX
The HD•CTR
is specifically designed for
Home Theater. It exceeds the specifica-
tions set forth by Dolby Laboratories for the
accurate reproduction of Dolby Digital
encoded sources.
Directed Sound Field Geometry™
(DSFG)
BX
The HD•CTR
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 frequen-
cy and phase response approximately 15°
off-axis from the tweeter. This gives opti-
mum performance to a seated listener
even if the HD•CTR
BX
or below a TV or screen.
Mica Filled Polypropylene Woofers
with Inverted Butyl Rubber Suspension
The unusually stiff and light polypropylene
cone is filled with mica to enhance its rigid-
ity for the fastest, most accurate response.
Additionally, the use of an Inverted Butyl
Rubber Suspension offers substantial bene-
fits including: increased movement without
mechanical limitations; weather resistance;
and improved midrange damping for better
detail and clarity.

ElastoDynamic ™ Hybrid Dome Tweeter
Constructed from a composite matrix of
elastomers and natural fiber substrates, the
ElastoDynamic™ tweeter offers extended
high frequency response without any harsh
ringing or overshoot.
Video Shielding
The HD•CTR
BX
utilizes special video
shielding to enable it to be installed in
close proximity to a video monitor without
negative effects on picture quality.
Acoustic Fine Tuning
The HD•CTR
BX
features rear-panel mounted
Acoustic Fine Tuning Controls. The
HD•CTR
BX
's controls enable optimization of
the high frequencies and dialog with 3dB of
Treble Cut and 3dB of Dialog Enhancement.
DSFG ™ Defeat
The HD•CTR
BX
features a rear-panel mount-
ed switch which enables the installer to
switch the Directed Sound Field Geometry
feature ON or OFF. (It is useful to switch it
Off when the speaker is installed at ear level,
for example, behind a perforated screen).
BumpBack ™ Woofer Magnet(s)
Niles engineers have utilized a unique
magnet construction allowing far greater
"throw" or voice coil excursion. This
allows a new level of deep bass perfor-
mance to be achieved.
