Note: The Niles Audio OS5.3 is packaged as a pair.

Drivers: Each OS5.3 features a 5″ 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 OS5.3 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 OS5.3 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 OS5.3 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 5/8″ to the overall height of the speaker.
