The PRX418S is a compact, high power subwoofer system containing a JBL Selenium 457 mm (18") woofer in a front-loaded, vented enclosure. The enclosure is designed to present a minimum frontal area.

The system offers complete input connection ﬂexibility for compatibility with a variety of cabling schemes. The input panel incorporates a pair of Neutrik Speakon®NL-2 / ¼" TS phone combo jack connectors wired in parallel. The PRX418S is supplied with pins +1/-1 connected to the woofer.

The enclosure is constructed of birch/poplar multi-laminate hardwood and coated in JBL’s rugged DuraFlex™ ﬁnish. The distinctive 16-gauge steel grille is CNC-machined for precision. The grilles are internally lined with an acoustically transparent screen to provide additional driver protection and give a very professional appearance.

JBL continually engages in research related to product improvement. Some materials, production methods and design reﬁnements are introduced into existing products without notice as a routine expression of that philosophy. For this reason, any current JBL product may differ in some respect from its published description, but will always equal or exceed the original design speciﬁcations unless otherwise stated.
