Our take on the Niles OS7.3

by Marshall Chase

Outdoor speakers let you move the party outside

Outdoor speakers are built tough -- they laugh at wind, rain and weather. Tuck a pair under your eaves and they'll pump out the tunes to keep everybody smiling and swaying at your next cookout or pool party. We also have some "rock" speakers that blend seamlessly into your landscaped lawn or garden.

Fresh tunes in the fresh air

Your enjoyment of music doesn't have to stop the moment you step outside your home. That's why Niles put their custom audio expertise into all-weather speakers like the OS7.3. It boasts a 7" mica-filled polypropylene woofer with a rigid design to reduce bass break-up. Its patent-pending integrated baffle assembly increases the woofer cone area relative to the size of the enclosure, for fuller low-frequency response. The 1" fluid-cooled UltraSilk® dome tweeter delivers clear, detailed highs across a wide listening area.

These speakers can stand out in the open or be tucked discreetly in corners or under eaves with their integrated mounting brackets. A tough weather-proof design means they'll deliver great performance for years and years. Plus they're covered by Niles' limited lifetime warranty.

Overview: The Niles Audio OS7.3 indoor/outdoor speakers are designed for outdoor installations, or for use indoors. They come with an integrated mounting bracket for outdoor installations, and a shelf stand for placement on a bookshelf. These high performance speakers are housed in weatherproof enclosures that can handle extreme hot, cold, and moist environments.

Note: The Niles Audio OS7.3 is packaged as a pair.

Drivers: Each OS7.3 features a 7" Mica-filled Polypropylene cone woofer and a 1" Ultrasilk dome tweeter. The integrated woofer/baffle design increases the cone area, which enhances the low frequency response. The butyl rubber woofer surround helps damp resonance and provides exceptional durability. The fluid-cooled tweeter has an ultra-wide dispersion pattern to give you clear, detailed high frequencies.

Paintable: The OS7.3 speakers and removable grilles can be painted to match your décor. Each speaker includes a clear plastic paint mask let you cover the drivers while the paint is applied to the enclosure.

Weatherproof: Niles Audio OS speakers are designed to exceed the military's strict specifications for preventing corrosion (MIL-STD-883D).

Speaker Terminals: The OS7.3 is equipped with a pair of inverted 5-way binding post terminals, which repel moisture. The terminals can accept up to 12-gauge bare speaker wire, pin connectors, spade lugs, and dual and single banana plugs. For wire runs of less than 80 feet, 16- to 18-gauge wire is recommended. You should use 14-gauge wire for runs of 80-200 feet, and 12-gauge wire for runs over 200 feet.

Installation: The speakers can be mounted vertically or horizontally with the integrated bracket, which attaches to the speaker on the top and bottom with easy-to-remove screw knobs. The bracket has a variety of holes for permanent installation by screws or nails. There are also two keyhole slots for easy removal, if desired. The bracket also has a hole for passing through the speaker wire. There is a 1/4"-20 threaded insert on the back for use with 3rd party wall mount brackets.

Shelf Stand: For shelf placement, the OS7.3 comes with a 3-point shelf stand. After removing the bracket, the stand can be secured to the speaker by the bottom screw knob. The shelf stand adds approximately 3/8" to the overall height of the speaker.
