INTRODUCTION
The OS-20 marries unparalleled listening satisfaction with the freedom to listen to music anywhere! You can use them indoors and outdoors (even on a boat). The extraordinary sonic performance of the OS-20 was achieved by harmoniz­ing unique and proprietary technology with the most advanced manufacturing methods and materials available.
The OS-20 is a two-way speaker in an acoustic suspension enclosure. The cab­inet is shaped to fit neatly into corners or eaves. It is supplied with a swiveling mounting bracket for easy installation anywhere. In addition, our engineers constructed the OS-20's to withstand the stresses and strains of the world out­side! For the first time, serious listeners can enjoy a concert on the green in their own back yard.

FEATURES & BENEFITS
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
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.
Hybrid Dome Tweeter
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 opti­mized 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.
FEATURES & BENEFITS
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 excur­sions 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 OS­20'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 ampli­fier with a Niles speaker selector.
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 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 addi­tion, two feet are molded into the base of the cabinet to give added stability.

FEATURES & BENEFITS
Premium Gold-Plated Five-Way Binding Posts
PAR TS GUIDE
PAR TS GUIDE
Gold plating gives you a corrosion-free high quality speaker wire connection. The connectors' five-way design allows you to use any of the most popular wire terminating methods.
Easy Finger-Sized Access
The binding posts are mounted upside down in a molded recess on the back of the OS-20. This prevents water from pooling at the connection. The recess is large enough to fit your fingers, so you can easily loosen or tighten the speaker connections.
Weather-Resistant Construction
The hardware is made of stainless steel or brass, and the binding posts are plat­ed with gold. The bracket and grill are made of aluminum (oxidation is self-lim­iting with aluminum) and it is powder coated (powder-coating gives absolutely even coverage everywhere) for the ultimate rust-proof construction. The enclo­sure itself is shatterproof. The OS-20’s components are weather-resistant, UV­resistant, salt-water corrosion-resistant, and immune to damage from tempera­ture extremes (-50 to over 200 degrees Fahrenheit).
