INTRODUCTION

The OS-25 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-25 was achieved by harmoniz­ing unique and proprietary technology with the most advanced manufacturing
methods and materials available.

The OS-25 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-25'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.

Low Diffraction MicroPerf™Aluminum Grille and Front Baffle

The aluminum MicroPerf

™

grille of the OS-25 has hundreds of precisely sized
perforations, creating an acoustically transparent grille. The aluminum construc­tion resists oxidation enabling years of trouble-free operation in the harshest
conditions. 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-25 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-25 to be pointed at the
optimum listening position and locked into place quickly and easily.

Easy Three-Way Mounting System

1. The OS-25 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-25 is equipped with 1/4-20 threaded inserts for OmniMount

or

custom brackets.

Stable Shelf Placement

The bracket knobs serve as one of the speaker's feet when the OS-25 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

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-25’s
crossover provides excellent stereo imaging and low distortion.

1” Teteron Tweeter

In the past, every weather-resistant speaker has disappointed listeners with a
fatiguing and harsh treble sound caused by tweeter ringing. The OS-25’s 1”
Teteron tweeter utilizes a tri-laminate design consisting of an inner textile
layer which forms the dome, a high damping layer to kill unwanted reso­nances, and an outside layer of urethane to add stiffness and prevent breakup
modes. The result is a transparently clear, sweet, natural sounding tweeter
which still maintains extended frequency response.

6-1/2” Injection Molded TCC Woofer

The unusually stiff and light injection molded TCC 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 6-1/2” woofer 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.

Rigid, Acoustically Inert Enclosure

The cabinet of the OS-25 is composed of mineral filled polypropylene. This
material is extremely non-resonant. All you hear is the music.
