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
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
NOTE
protection will reset and the tweeter will return to
normal operation.
