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 construc-
tion 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 reso-
nances, 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 sur-
round, 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.
