Application:
Compact and powerful, the PRX618S
offers the performance of an 18 in
subwoofer in a package not much larger
than a typical 15 in sub. With a pole
receptacle (that accepts a SS3-BK or SS3BK24) on the top panel and integrated
stereo pass-through, with selectable HP
filter, this is the perfect complement to the
PRX600 full-range systems. Configured with
a PRX612M or PRX615M, the result is a
highly transportable, high performance
subs/satellite system. The addition of a
polarity reverse option further enables
integration with any top cabinet.
The PRX618S is a high performance selfpowered compact subwoofer system. The
PRX618S is comprised of a 268G 460 mm
(18 in) Differential Drive
and magnetic gap, neodymium woofer
driven by a Crown Class-D power amplifier.
The amplifier input panel offers stereo or
mono line level inputs via balanced XLR
connectors as well as a single channel
speaker level input via a ¼ in TS phone
jack. Signal processing, crossover
functionality and limiting for the system is
integrated into the input section
functionality. Overall subwoofer input
sensitivity is controlled by a single easy grip
knob and a simple switch enables polarity
reversal for sub/satellite system
optimization. Signal present and limit lights
indicate performance status.
All PRX600 cabinets are built from a
combination of 25 mm (on the top and
bottom for added rigidity) and 18 mm,
strong, lightweight poplar plywood made
structurally sound with tongue and groove
joints. All PRX600 Series cabinets are
protected by JBL’s tour proven DuraFlex™
finish. Grilles are made from dent-resistant
16 gauge steel and handles are made from
lightweight, glass-filled nylon for added
strength and durability.
