Getting Started
Please inspect your loudspeakers carefully. Notify your Polk dealer if you notice any damage or missing items. Keep the carton and packing material; this will do the best job of protecting your loudspeakers if they must be transported.
Safe Limits of Operation
Damage to loudspeakers can occur when an amplifier, regardless of its wattage, is made to play at higher listening levels than it can produce at low distortion levels. This is usually beyond the “noon or 1 o’clock” position on the volume control. Operation at this level can result in very high levels of audible distortion originating in the amplifier, which can add a harsh, gritty sound to your listening material. Contrary to popular belief, a loudspeaker is more likely to be damaged by trying to get too much volume from a low-powered amplifier or receiver than from a high-powered one

Flush mount tweeter mounting
- Check for proper clearance: The flush mount kit is 1” (26mm) deep.
- Mark the center of the spot and cut a 2” (50.8mm) diameter hole using a hole saw, drill bit, or razor knife.
- Assemble the cup, clamp, and machine screw loosely as shown.
- Route wires through the round opening in the bottom of the cup.
- Press the assembly into the 2” (50.8mm) diameter hole until the clamp edge is below the mounting surface, then tighten the screw. The legs of the clamp can be bent outward by inserting a screwdriver through the holes in the cup while still mounted.
- Connect wires from the tweeter terminals of the Crossover to the tweeter itself using the fast-on connectors. Connect the red wire from the (+) terminal of the Crossover tweeter output to the red (+) wire from the tweeter.
- Mount the tweeter by snapping it into the mounting cup.

Surface mount tweeter mounting
- Using the base of the surface mount cup as a template, mark the screw hole and drill them using a 1/8” (3mm) drill bit. Drill a second hole (for the speaker wire) using a 3/16” (5mm) drill bit.
- Screw the surface mount cup to the panel.
- Push the tweeter wires through the open area at the bottom of the cup and the 3/16” (5mm) hole in the panel.
- Connect wires from the tweeter terminals of the Crossover to the tweeter wires using fast-on connectors. Be sure to connect the red wire strand from the tweeter to the (+) terminal of the crossover tweeter output.
- Mount the tweeter by snapping it into the mounting cup.
