Compact and powerful, the PRX518S
offers the performance of an 18 in.
subwoofer in a package not much larger
than a typical 15" sub. With a pole
receptacle (that accepts a SS3-BK) on the
top panel and integrated stereo pass-thru,
with selectable HP filter, this is the perfect
compliment to the PRX500 full-range
systems. Configured with a PRX512M or
PRX515; the result is a highly
transportable, high performance subsatellite
system. The addition of a polarity
reverse options further enables system
optimization.

The PRX518 is a high performance selfpowered
compact subwoofer system. The
PRX518S is comprised of a 2044E 460 mm
(18") VGC™ (Vented Gap Cooled) woofer
driven by a Crown International Class-D

The enclosure is constructed of quality
plywood and coated in JBL’s rugged
DuraFlex™ finish. An integrated pole
mount on the top enables an easy
sub/satellite configuration. The CNCmachined
steel grille wraps around the
sides of the enclosure so there are no
protruding lips on the front of the box to
create acoustical interference. The grille is
also lined with an acoustically transparent
foam to provide additional driver
protection.

The amplifier input panel offers stereo
inputs with XLR or ¼ inch jack
compatibility. A user selectable crossover
ensures a smooth transition to full-range
system connected to the stereo outputs.
Signal present and overload lights indicate
the system status and assist in setting the
optimum level, via the level control knob.
