MPN: OS7.3 White
Integrated Woofer/Baffle Assembly increases the woofer cone-area to cabinet-width ratio for enhanced bass output
Mica-Filled Polypropylene Woofer Cone reduces breakup and lowers distortion
Butyl-Rubber Woofer Cone Surround damps resonance and provides exceptional durability
7" Mica-filled polypropylene cone is extremely rigid to reduce breakup and lower distortion
1" UltraSilk dome with fluid-cooling and ultra-wide dispersion for clear, detailed and extended high frequencies
8 ohm Impedance
Weatherproof Engineering enables OS loudspeakers to handle extreme hot, cold and moist environments, exceeding the military's strict anti-corrosion specifications MIL-STD-883D
Advanced Material Science elevates appearance and longevity of the cabinet and grille, plus enhances the performance of the woofers, tweeters and crossovers
Architecturally-Friendly Design delivers stellar acoustical performance, yet tucks discreetly away into corners and under eaves
Low-Diffraction Grille and Front Baffle ensures that the sound waves emanating from the woofer and tweeter are not reflected by the surrounding parts of the loudspeaker for precise imaging and acoustical accuracy
Rigid, Acoustically-Inert Cabinet prevents transmission of unwanted vibrations for clean and dynamic bass response
All-Weather Versatility reduces installation limitations to provide great sound from the beaches of Miami to the harsg winters of Minneapolis
Home Theater Applicability enables OS loudspeakers to be used as left, center, right or surround loudspeakers in home theater systems
Integrated Mounting Bracket and Shelf Stand provide a variety of secure, quick and easy mounting solutions
Tapered Shape facilitates mounting in corners and under eaves
Inverted Gold-Plated 5-Way Binding Posts repel moisture and ensure positive connections in virtually any conditions over long periods of time
Recommended Amplifier Power for the this loudspeaker is 5 to 150 W per channel
65Hz - 21kHz +/-3dB Frequency Response
91dB Sensitivity for 2.83V pink noise
Enclosure, brackets and grilles of the loudspeaker can all be painted to match the surroundings
Package of 2 Speakers
Note: For most applications, we recommend using 16 or 18-gauge wire. For wiring runs longer than 80 feet, we recommend 14-gauge wire. The binding posts on OS loudspeakers accommodate up to 12-gauge wire directly. Larger sizes can be accommodated using spade, banana, or pin connectors.
