WALL MOUNTING THE RTi 28 AND RTi 38 BOOKSHELF LOUDSPEAKERS

The RTi Series Bookshelf Loudspeakers feature a rear firing Power Port which doubles as a wall

mounting bracket. Follow the steps below to safely wall mount these speakers. Wall mounting

requires basic skills in with tools such as a drill and a screwdriver. If you are in doubt that you

possess the necessary skills or tools, consult your Polk Audio dealer, or a professional installer.

•Make sure the material on which you plan to mount the speakers (plaster, drywall, paneling, stone, etc.) can support the weight of the speakers (RTi28=approx 15lbs/6.8kg ea., RTi23=approx 20lbs/9.1kg ea).

•Make sure the locations you select do not conceal electrical wiring or plumbing.

•Prior to installation, hold the speaker in the chosen location to make sure it safely clears obstacles such as ceiling, adjacent walls, corners, beams, lighting fixtures and door/window frames.

•Using the keyhole slot in the bracket template (included), mark the installation location of the keyhole slot with a pencil [figure 8]. Orient the template so that the small end of the keyhole slot facing “up” according to the direction of installation.

•If you are certain that there is a stud behind the wall surface, drive #10 screws (not included) through the wall and into the stud [figure 9a].

•If there is no stud behind the wall at the chosen location, install #10 wall anchors (not supplied) into the wall by following the wall-anchor-manufacturer’s instructions. Always use two wall anchors and two screws per speaker [figure 9b].

•For masonry walls, use a masonry drill bit and #10 masonry anchor and screw (not included).

•Tighten screws into stud or wall anchors, leaving screw heads protruding 1/16” (1.6mm).

•Line up the keyhole slots on the back of the Power Port so that the screw heads pass through the large center hole of the slots.

•Let the speaker and slide straight down, allowing the screw head to slip behind the smaller end of the keyhole slot [figure 10].

•Tug gently on the speaker to make certain that the screws and bracket are properly aligned and that the wall anchors are secure.

•If the bracket is not held snug against the wall by the screw heads, remove the speaker from the wall, drive the screws in a little further and then remount the speaker.

SAFE LIMITS OF OPERATION

Your Polk loudspeakers are made with the highest quality materials for years of trouble-free performance. However, damage to loudspeakers can occur when an amplifier, regardless of its wattage, is made to play at higher listening levels than its power can clearly produce (usually beyond the “1 to 2 o'clock” position on the volume control). This results in very high levels of audible distortion, originating in the amplifier, that can add a harsh, gritty sound to music. Contrary to popular belief, a speaker is more likely to be damaged by trying to get too much volume from a low-powered amp or receiver than from a high powered one.

TAKING CARE OF YOUR RTi SERIES LOUDSPEAKERS [figure 11]

Your new RTi Loudspeakers are finished in natural wood veneer. Clean and dust the veneer

with a damp cloth only. Do not use furniture polish on the veneer. Carefully vacuum the grilles

to remove dust.
