Can I suspend TR
/ MR / SR Series enclosures?
TR / MR / SR Series cabinets were NOT
designed for fixed installations that require the cabinet to
be suspended. The enclosures are NOT
reinforced and lack suspension points for fixed installations.
Suspending these cabinets represents a
serious safety hazard. As an alternative, consider
the Sound Power, Marquis or Array Series. These systems have
properly designed suspension points installed and are reinforced.

can I get "loop-through" power cables
for my EON Powered Series speakers?
EON powered speakers use a standard IEC male connector for AC
power. A female connector is provided for looping AC power through
to another EON speaker. JBL Customer Service sells male and
female cable-end IEC connectors that can be installed on standard
3 conductor electrical power cable. The parts numbers are CP22S
(the female connector) and CP22R (the male connector). Only
those with the skill and knowledge to fabricate safe, reliable
electric power cables should install these connectors.
