INTRODUCTION
The HD High Definition group
offers loudspeakers designed for
superior sonic quality and durability. They employ advanced
technology components designed
to extract all of 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.
CONTINUED OTHER SIDE
Mica-Filled Polypropylene
Woofers
The mica-filled polypropylene
cone achieves new standards in
transient speed and dynamic
range because of its phenomenal
rigidity and improved stiffness to
mass ratio. The inverted butyl
surrounds, the BumpBack
TM
magnets and the rigid steel basket
are all optimized for large excursions of the cone. In this way,
each of the HD speakers deliver
exceptionally deep and detailed
bass at realistic sound pressure
levels, without the mechanically induced limiting and distortion
of typical designs.
ElastoDynamicTMHybrid
Dome Tweeter
Constructed from a composite
matrix of elastomers and natural
fiber substrates, the ElastoDynamic
TM
tweeter offers extended high frequency response without any harsh ringing or overshoot. Additionally, the elastomers offer the added benefit of
weather resistance, making it
uniquely suitable for use outdoors or in moist environments.
Acoustic Fine Tuning
An installer set “NORMAL/PRES-
ENCE” control located behind
the speaker baffle allows the
speaker to be tuned to your particular room acoustics. You can
adapt the sound for a room with
lots of furniture, heavy drapes
and wall to wall carpeting.

INTRODUCTION
FEATURES AND BENEFITS
®
Weather-Proof
Construction
All of the drivers, the frames
and the baffles are weatherproof. The aluminum grilles
are rustproof and the mounting
screws are all stainless steel.
Absolutely Flush to the
Wall Appearance
The unique mounting system of
the HD loudspeakers powerfully clamps the frame to the
bracket, sandwiching the wall
material between them.
Because the clamping action is
totally uniform around the
frame there are no shadows or
gaps between the wall and the
frame. Additionally, the Niles
mounting system is carefully
optimized to stiffen the surrounding drywall and prevent it
from resonating. You hear only
the music, not the drywall.
Infrared Sensor Mount
The speaker baffle has a locator
designed for the Niles MS-1
MicroSensor,™ a miniature
infrared sensor. The MS-1
installs discreetly behind the
aluminum grille and therefore
minimizes wall clutter in your
home. When you want to control your equipment, you simply
point your remote control at the
speaker with the MS-1 installed
from up to 15feet away.
X-Matrix™Reinforced
Baffle
The X-Matrix Baffle design uses
specially molded ribs to add
rigidity to the baffle.The end
result is better bass and
improved midrange detail.
Six Ohm Impedance
HD speakers are designed to be
placed in multi-room systems
with many pairs of speakers. The
six ohm impedance is a very
easy electrical load for most
amplifiers. This allows many
pairs of HD speakers to be wired
to a single amplifier using a
Niles speaker selection system.
Low Diffraction, Paintable
Aluminum or Cloth Grilles
HD speakers are available with
aluminum or cloth grilles. The
painted rustproof aluminum
grille has hundreds of precisely
sized perforations, creating an
acoustically transparent grille.
The cloth grille is covered with
a color coordinated acoustically transparent cloth.

Three Stage Installation System
Prevents Theft and Simplifies
Painting
You install only the parts you need for a
particular stage of construction. When
the framing and wiring are finished, you
install the
bracket
. After the drywall is up,
but before the painter begins to paint,
you install the
frame
and provide the
rustproof aluminum
grilles
to the painter
so that they can be painted to match the
surroundings. Only when construction is
completely finished do you put the valuable
speaker
in the wall.
Easy Retrofit Installation
Designed for ease of installation, the
Niles mounting system makes retrofit
installations simple and fast. A supplied
template assures fast and accurate hole
cutting. The bracket slips behind the drywall and the screws secure the bracket to
the frame, sandwiching the drywall
between them. The speaker baffle attaches to the frame, and the grille mounts
over the speaker.
Instant Speaker Changes
An MP or BG speaker can be substituted
for the HD, if the frame size is identical
(e.g. HD-525 to BG-525). You can quickly change the speaker by removing the
grille, undoing the mounting screws and
replacing just the speaker baffles.
Hole Saving Bracket
New Construction Wings allow the
Bracket to be installed as a “Hole Saver”
before the drywall goes up. The drywall
contractor cuts the hole in the drywall as
it is installed, reducing the chances of
misplaced wire.

and the connection terminals are
