INSTALLATION

Installing the Tweeter for the JRX650

The separate tweeters included with the JRX650 have a variety of mounting applications. During installation, make sure the tweeter is positioned and aimed towards the listener's ears.

 

The JRX speakers include a device in the tweeter's

NOTE

crossover to protect it from damage. In the case of

extreme overload, this device will reduce the

 

 

power into the tweeter. If the tweeter is

 

deactivated, please turn down the volume and wait

 

for a moment. After cooling down, the tweeter

 

protection will reset and the tweeter will return to

 

normal operation.
