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.
Technical Assistance or Service
If, after following the hookup directions, you experience difficulty, please double-check all wire connections. Should you
isolate the problem to the loudspeaker, contact the authorized Polk dealer where you made your purchase, or contact
Polk Customer Service 800-377-7655 (M-F, 9-5:30 EST, US only) or via email [email protected]. Outside the US, call
410-358-3600. More detailed information—including audio how-to articles, FAQs, and online manuals—is available on our

Flush mount tweeter mounting
1. Check for proper clearance:
The flush mount kit is 1”
(26mm) deep.
2. Mark the center of the spot and
cut a 2” (50.8mm) diameter hole
using a hole saw, drill bit or
razor knife.
3. Assemble the cup, clamp and machine
screw loosely as shown.
4. Route wires through the round opening in the bottom of the cup.
5. 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.
6. Connect wires from the tweeter terminals of the Crossover to the tweeter itself using the faston connectors.
Connect the red wire from the (+) terminal of the Crossover tweeter output to the red (+) wire from the tweeter.
7. Mount the tweeter by snapping it into the mounting cup.
