Polk Audio EX SERIES II There is sufficient depth behind the spot you choose, Still mounted

The Polk EX2500 tweeter offers two mounting options for installation flexibility. Mounting Option #1 – Surface mounting the EX2500 Tweeter

1.Using the base of the surface mount cup as a template, mark the two screw holes and drill using a 1/8 inch drill bit. Drill a third hole (for the speaker wire) using the 1/4 inch drill bit.

2.Attach either surface mount cup (angled or straight) to the panel using #8 screws of appropriate length for the panel.

3.Push the tweeter wires through the open area at the bottom of the cup and through the 1/4" hole in the panel.

4.Connect wires from the tweeter terminals of the crossover, to the tweeter wires, using the faston connectors. Connect the red wire strand to the (+) terminal of the crossover tweeter output and to the red wire on your tweeters.

5.Mount the tweeter by snapping it into the mounting cup and turning the tweeter

clockwise, locking the tweeter in place.

Mounting Option #2 – Flush mounting the EX2500 Tweeter

1.	Remove the panel on which you are going to mount the tweeter and check for proper
	clearance behind it. The flush mount kit is 1/2 inch deep. Measure to make sure
	there is sufficient depth behind the spot you choose.
2.	Mark the center of the spot and cut a hole with the 1 3/4 inch hole saw attachment
	for your power drill. Go slow. You can use a razor knife instead of a drill if you prefer.
3.	Assemble cup, clamp, and machine screws loosely as shown in Figure 4.

4.	Route wires through the round opening in the bottom of the cup.
5.	Press the assembly into the 1 3/4 inch hole until the clamp edge is below the
	mounting surface, then tighten the screw. The cup will clamp down to the surface as
	the screw is tightened. In the case of a thick mounting surface, 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 wires, using
	the faston connectors. Connect the red wire strand to the (+) terminal of the
	crossover tweeter output and to the red (+) wire on the tweeter.
7.	Mount the tweeter by snapping it into the mounting cup and turning the tweeter
	clockwise, locking the tweeter in place.

EX2500 Component Tweeter Hook-up

When purchased as a separate unit, the EX2500 tweeter includes a first order (6dB/octave) crossover network integrated into the tweeter assembly. This high pass filter allows the EX2500 to be used with other components. It is important to maintain correct polarity. The red wire connects to the positive (+) amplifier terminal and the black to the negative (-) amplifier terminal.

If your system contains an active crossover, you may bypass the in-line crossover and wire the tweeter directly to the output terminals of an amplifier which has a high pass filter (crossover) on its input. The minimum crossover point should be 2 kHz at 12dB per octave.

DO NOT USE THE TWEETER WITHOUT A CROSSOVER NETWORK. Damage to the tweeter from thermal overload will result without the protection provided by a crossover and will void your warranty.
