JL Audio C3-650-XO Convertible Components, Component System Set-Up, Coaxial System Set-Up

CONVERTIBLE COMPONENTS

C3 Convertible Components give you the option of installing the speakers as separate component speaker systems or as coaxial systems (tweeters mounted onto the center of each woofer).

Note: If the C3 system is to be used in a coaxial configuration, the phase plugs must be removed to accept the tweeter and tweeter post.

Component System Set-Up

The Component configuration of the C3-650 is achieved by wiring the tweeter to the crossover separately and installing the included phase plugs onto the center of each woofer. The woofers are factory-packaged in the component system configuration with phase plugs installed.

The phase plugs attach to the woofers using a simple bayonet (twist and lock) mechanism.

To remove the phase plugs, simply apply downward pressure with your thumb and index finger and twist 1/4 turn counteclockwise until released. Then pull the phase plug off the receiver.

To reattach the phase plugs, align the two tabs on the inside of each phase plug with the grooves on the outer diameter of the receiver in the center of the woofer. With these aligned, slide the phase plug down into place until it stops, applying gentle pressure. To lock, push down firmly/evenly on the plug with thumb and index finger and turn 1/4 turn clockwise.

For woofer mounting instructions, please refer to Pages 10-11 of this Manual. For separate tweeter mounting instructions, please refer to Pages 12-13 of this Manual.

Coaxial System Set-Up

The Coaxial configuration of the C3-650 is achieved by installing a tweeter onto the center of each woofer using the supplied coaxial tweeter posts.

First, remove the phase plugs from the woofers (if present) by pushing down firmly/evenly on the plug with thumb and index finger and turning 1/4 turn counter-clockwise to unlock and remove. The phase plugs will not be used in coaxial configuration and should be set aside for possible future use.

Next, route the tweeter’s Positive (+) and  Negative (-) wire leads through the center of the coaxial tweeter post from the large tweeter-cup end and out the smaller end (See Figure A). The tweeter mounts to the coaxial tweeter post using a simple bayonet (twist and lock) mechanism. To attach the tweeter to the post, observe the indented locking slots on the outer edge of the tweeter body and align these with the tabs visible on the inside walls of the tweeter cup portion of the tweeter post. The tweeter should slide into place easily and can then be locked by pushing down on the tweeter and giving it a small clockwise turn (See Figure B).

With the tweeter installed into the tweeter post, connect the Positive (+) red wire lead on the tweeter to the larger male connection tab in the woofer’s center, followed in the same manner, by the  Negative (-) black lead to the smaller connection tab. (See Figure C).

Now, note the two tabs on the inside of the bottom end of the tweeter post. Align these tabs to the channels visible on opposite sides of the receiver in the woofer’s center. While tucking the wires into the tweeter post, slide the tweeter post down into place until it stops and is ready to be locked. To lock, push down firmly/evenly on the tweeter post with thumb and index finger and turn 1/4 turn clockwise. 

(See Figure D).

For woofer mounting instructions, please refer to Pages 10-11 of this Manual.
