Compact and powerful.

The JBL PRX518S offers the performance of an 18" sub-woofer in a package not much larger than a typical 15" sub. With a 36mm pole receptacle that accepts the JBL SS3-BK speaker stand on the top panel and integrated stereo pass-thru, with selectable HP filter, this is the perfect complement to the PRX500 full-range systems. Configured with a PRX512M or PRX515; the result is a highly transportable, high performance sub-satellite system. The addition of a polarity reverse option further enables system optimization.

The PRX518 is a high performance self-powered compact sub-woofer system. The PRX518S is comprised of a 2044E 460 mm (18") VGC (Vented Gap Cooled) woofer driven by a Crown International Class-D digital power amplifier. A propriety digital processing chip (DSP) chip is at the core of a fully featured input section, providing user selectable crossover functionality, polarity optimization, protection, dynamic limiting and discrete component optimization.

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 CNC machined 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 1/4 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.

Worked with a few powered and non powered subs, as for the JBL PRX518S great built easy, on the back, but not to impressed with the bottom sound, not that punch i was looking for, great edition to powered JBL EONS 2, while working with powered gear ,not the same sound as the old fashion wooden cabinets, but let move on to new and updated gear,not a bad piece for the price.

my pastor had told me that he thought we should invest in a sub and asked me what brand we should go with. I had always heard good things about JBL and Crown. This unit just fit in our budget so we bought it. We connected it to our passive 16 channel Mackie board. We spent a few hours on the placement and found a spot where it sounded great and most dead zones were eliminated. Keep in mind we just wanted a little extra "kick" on the bottom-end so that we could take some of the workload away from our main loudspeakers. We came back 2 days later and the unit was as dead as the proverbial doornail. We checked fuses and connections, sent it back and received a new one. Sounded great and lasted about 2 months. Dead once again. Haven't sent this one back yet. Stay tuned.

Doesn't have the punch of my Yorkville 18" sub, but it weighs 30% less. Much better than the EONs. Pairs nicely with the 512M for DJ work. Haven't used it for any band work yet, but need to see how it stacks up against Crest-powered Turbosounds.

Portable High-Powered Sub

I purchased the JBL PRX518S powered subwoofer a couple of months ago and have been extremely impressed with it's weight and ultra-portability. Moreover, the performance and sound with the built in D-series Crown amplifier is unsurpassed in feature and functionality. Prior to making this purchase, I had evaluated the Mackie SWA1801. The punch was there, however, the weight of the unit was a limiting factor, considering that I use the unit for live sound and playback. You won't go wrong with this new series from JBL. Excellent product.
