    Comments about JBL Pro JBL MRX-518S 18In/500W @ 8 Ohms Subwoofer *:

    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!

      Comments about JBL Pro JBL MRX-518S 18In/500W @ 8 Ohms Subwoofer *:

      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.

        • Q:

          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!

            A:

            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.
