General Information
Caution: The XRT1K weight is 168 pounds (76.2kg). It re-
quires three or more persons to safely handle the Loudspeaker
System.
1. Loudspeaker Cables of adequate size are important to en-
sure that there will be no significant power loss or heating.
Cable size is specified in Gauge numbers or AWG (Ameri-
can Wire Gauge). The smaller the Gauge number, the larger
the wire size:
If the Loudspeaker Cables are 50 feet (38.1m) or less,
use at least 12 Gauge (AWG) wire size or larger.
If the Loudspeaker Cables are 100 feet (76.2m) or less,
use at least 10 Gauge (AWG) wire size or larger.
2. For additional connection information, refer to the owner’s
manual(s) for any component(s) connected to the XRT1K
Loudspeaker.
3. The XRT1K’s built-in speaker protection incorporates five
automatic resetting solid-state devices in the crossover
networks. One protects the tweeters, one for the midranges
and three for the woofers. The protection allows a certain
amount of overdrive but extended periods will trigger pro-
tection. If an obvious lack of high, mid or low frequencies
is noticed, the Protection Device may have activated. These
devices will automatically reset when the volume level is
reduced significantly and kept low until the output of the
affected Loudspeaker Element returns to normal.
4. When the XRT1K Loudspeaker System is driven by more
than one amplifier, the output levels of the different ampli-
fiers connected to the Loudspeaker System must be adjusted
to achieve a proper balance between the low, midrange
and high frequencies reproduced. This adjustment is best
achieved through the use of audio test equipment operated
by a qualified installer.
