Rigid, Acoustically Inert Enclosure
The cabinet of the OS-20 is composed of mineral filled polypropylene. This
material is extremely non-resonant. All you hear is the music.
Low Diffraction Grill and Front Baffle
The grill of the OS-20 has hundreds of precisely sized perforations, creating an
acoustically transparent grill. The front baffle is gently curved in a radius opti-
mized for the best sound. Sound waves emanating from the woofer and the
tweeter are not reflected by the surrounding parts of the speaker.
Tapering Shape
The cabinet of the OS-20 is shaped so that the speaker will tuck discretely
away into corners or under eaves.
Swiveling Bracket
The U-shaped bracket and bracket knobs allow the OS-20 to be pointed at the
optimum listening position and locked into place quickly and easily.
Easy Three-Way Mounting System
1. The OS-20 can be hung from a nail using the nail hole on the bracket.
2. The bracket can be screwed into the mounting surface using your hardware.
3. The OS-20 is equipped with 1/4-20 threaded inserts for OmniMount
®
or
custom brackets.
Stable Shelf Placement
The rubber inserts on the bracket knobs serve as one of the speaker's feet when
the OS-20 is placed directly on a shelf or desktop without the bracket. In addi-
tion, two feet are molded into the base of the cabinet to give added stability.
FEATURES & BENEFITS
Precision Crossover
An electronic dividing network inside the cabinet precisely distributes the
music to the woofer and the tweeter. The two-way design of the OS-20’s
crossover provides excellent stereo imaging and low distortion.
ElastoDynamic
™
Hybrid Dome Tweeter
In the past, every weather-resistant speaker has disappointed listeners with a
fatiguing and harsh treble sound caused by tweeter ringing. In the course of
developing our weather-resistant tweeter, we determined that tweeter ringing
can be damped out by a microscopically thin elastomeric coating on a natural
fiber dome substrate. The result is a transparently clear, sweet, natural sounding
tweeter which still maintains extended frequency response.
Long Throw Polypropylene Woofer
The unusually stiff and light polypropylene cone, the butyl rubber surround, the
substantial magnet, and the rigid steel basket are all optimized for large excur-
sions of the woofer. In this way, the five and a quarter inch cone can create the
same deep bass output of a much larger speaker moving small distances in and
out. The end result is rich satisfying bass from a compact, weather-resistant
loudspeaker.
Eight Ohm Impedance
The OS-20's are designed to be part of a multi-room audio system. The OS-
20's eight ohm impedance makes them compatible with virtually any amplifier.
In addition, this permits multiple pairs of OS-20’s to be wired to a single ampli-
fier with a Niles speaker selector.
