JBL MRX-518S 18-Inch Compact Passive Subwoofer

The MRX518S is a compact, high power subwoofer system containing a 2044G 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-4 connectors wired in parallel. The MRX518S is supplied with pins +1/-1 connected to the woofer. This may be easily reconfigured to work with cabling systems intended to drive subwoofers on pins +2/-2. For Subwoofer/Satellite configurations, the MRX518S is equipped with a top-mounted, 35 mm pole mount socket that can receive the optional SS3-BK pole. This can be used to mount speakers equipped with standard 35 mm pole sockets and weighing up to 100 lbs. The enclosure is constructed of top quality plywood, coated in JBL's rugged DuraFlex finish and is braced to maximize low-frequency performance. The attractive CNC-machined, 16-gauge steel grille is internally lined with an acoustically transparent screen to provide additional driver protection and give a very professional appearance.

Would the Crown ITX 4000 be a good match for two of these subs? And would you recommend running them on one channel or two? Thanks!
DJ C-Note on Jul 29, 2015
BEST ANSWER: The Crown XTI4002 Power Amplifier could be used to power a couple JBL MRX-518S 18in Subwoofers, however you would need to connect the two speakers in bridge mono mode.

Made in USA- Proud to own
Pros: Attractive Design,Great Sound Quality,Easy Setup,Easy to Mount

These speakers were my biggest purchase ever- and I wanted the best. They are lighter than my old subs and are more compact. I hve no problem projecting sound with two subs and 2 12's... love it. Even though the price was higher compared to the other brands available, I knew these were the best. I am not dissapointed!

Awesome Bass!
Pros: Easy To Connect,Compact,Attractive Design,Great Sound Quality,Powerful

I own a pair of these and always place them side by side at parties. At one party, they shook the ceiling and made the insulation particles fall. A few words of advice though, they only sound good when you have 1000 watts of power @ 4ohms per speaker and the right crossover. Also, don't expect these subs to produce anything under 45 hz, the ports just get noisy.
