FEATURES & BENEFITS

The CM6.1SI, CM6.3SI, CM6.5SI and CM8.5SI stereo input ceiling mount loud- speakers offer Niles durability, installation ease and are designed for unobtrusive installations.

CM Stereo Input loudspeakers are designed to deliver stereo sound from a single speaker. Dual tweeters housed in a stereo imaging faceplate deliver left and right channels (stereo) while a dual voice- coil woofer mechanically sums both left and right channels, creating a convincing illusion of stereo through a single speaker.

PACKAGE CONTENTS

•1 Piece Speaker With Grille

•1 Piece Hole Template/Paint Mask

CM Stereo Input speakers are ideal for locations where a stationary “sweet spot” is impossible or impractical such as hall- ways or entryways. They also deliver quality two-channel sound in locations that only have enough space to accom- modate a single speaker such as an enclosed shower.

INSTALLATION PROCEDURE

Figure 1

Checking for obstructions behind the ceiling surface.

1.Cut a foot-long piece of coat hanger. Bend the wire (creating a right angle) leaving 4-3/4” (5-3/8" for the CM8.5SI) at one end (this allows for the extra width of the mounting dogs). Poke the “L-shaped” wire into the pilot hole and turn it in a complete circle and move it into the ceiling cavity to make sure you have approximately 4” of depth. If the coat hanger movement is obstructed by anything, fill the hole(s) with spackle and try another location (See Figure 1).
