Introduction
Features and Benefits
Fully pivoting woofer and tweeter
A pivoting woofer assembly can adjust up
to 15° focusing bass and midrange tones
directly at the listening area for superb
imaging and unparalleled clarity. Within
the woofer assembly, the tweeter is housed
in its own low-diffraction pivoting assembly
that can adjust up to 17° in any direction to
create direct or diffused sound fields. The
independently pivoting woofer’s and tweet-
er’s superior design is patented, (U.S. patent
number 6,683,963).
12 AWG Push Terminal
The DS8.3 and DS8.5 loudspeakers
are manufactured with high quality gold
plated push terminals that insure that the
connection to the speaker cable is of the
highest quality available.
Moisture and UV Resistant
Construction
The DS8.3 and DS8.5 loudspeakers are
suitable for use in high moisture environ-
ments. The drivers are resistant to moisture
and UV exposure; the grille is made of
powder-coated aluminum. However, the
speakers are not waterproof and direct
contact with water should be avoided.
Engineered for Ceiling Placement
The increased popularity of cathedral
and vaulted ceilings pose a distinct sonic
challenge for conventional ceiling loud-
speakers. That is because conventional
ceilingloudspeakers radiate sound perpen-
dicular to their mounting surface, which
usually is not where the listening area is.
DS Directed Soundfield Loudspeakers
patented, independent pivoting woofer
and tweeter overcome this challenge and
allow sound to be directed into the listen-
ing area regardless of ceiling angle.
Installer Selectable Acoustic
Fine Tuning
Installers can select to fine tune the bass or
treble to accommodate reflective surfaces
and corner loading. This selection is
accomplished via the baffle-mounted
treble control (-1.5dB, flat and +1.5dB)
and PC board mounted bass jumper
(flat, -1dB, and -2dB).
4 or 8 ohm Selectable Impedance
The DS8.3 and DS8.5 give the installer
flexibility to select the speaker’s imped-
ance — 4 ohms for systems where
maximum current transfer and output
level is desired; 8 ohms for systems
utilizing multiple speaker pairs where
amplifier loading is a consideration.
MicroPerf
™
Grilles
The DS8.3 and DS8.5 employ Niles
exclusive MicroPerf grille construction.
The exceptionally tight hole pattern
provides acoustic transparency at all audio
frequencies and enables the speaker
elements to remain invisible. MicroPerf
grilles can also be painted to blend
seemlessly with the surrounding decor.
Niles DS Directed Soundfield loudspeak-
ers feature a fully patented, adjustable,
independently pivoting, woofer and
tweeter that enables the loudspeakers to
accurately recreate high fidelity sound
regardless of where they are located in
the ceiling — preserving interior design
integrity and delivering life-like sonic
quality that is not available from conven-
tional ceiling loudspeakers.
