Earth-pounding bass!

The JBL SRX728S Dual 18" Subwoofer is built to deliver smooth, clean, accurate low-end. With a pair of 18" Differential Drive woofers, it handles an amazing 1600W power (continuous). Large, open ducts minimize port turbulence and the heavily braced JBL enclosure assures tight, solid bass response. Designed to present a minimum frontal area, the subwoofer enclosure offers complete input connection flexibility with 2 Neutrik Speakon jacks. A recessed, external switch allows selection of either contacts +1/-1 or +2/-2 while an internal connector allows you to drive each woofer from a separate amplifier channel. The speaker cab is constructed of top-quality birch plywood and coated in rugged DuraFlex. Each woofer is housed in an isolated chamber and the enclosure is heavily braced to maximize low-frequency performance. The attractive CNC machined, 16-gauge steel grille is internally lined with acoustically transparent foam to provide the JBL SRX728S with additional driver protection and a very professional appearance. This subwoofer excels when paired with the PA speakers (sold separately).

With our Guaranteed Lowest Price, you can be assured of complete satisfaction and the lowest available price, or your money back!

  • Great For Night Clubs & Live Sound NOTHING BETTER

    As reviewed by Khyyam Cooper on 7/21/2009

    I use these subs in all the night clubs i design and build systems for. I chose these speakers because I have some for my DJ rig also. The system I did for Club Posh (Denver) has 5 of these on the main dance floor with 6 JBL SRX-725s flying from the ceiling. We used 8-Crown XTi-4000s and a DBX-Driverack. When i calibrated the system i used Hip-Hop, Metal, Country, R&B, Classical, Classic Rock, and jazz to test the different acoustical qualities of the speakers and they reproduced them FLAWLESSLY!!! The JBL/Crown system in Club Posh is by FAR one of the BEST sounding systems in Denver. People are constantly complimenting us on the sound there. I have a smaller set up just like the club for when I Dj and I have yet to hear other DJs with a system that compares..BUY THEM you wont regret it!!!

  • Impressive Still.

    As reviewed by OILWELLPRODUCTIONS on 8/13/2007

    My current rig uses six of these guys with six of the SRX 725 Tops. I have worked with almost every brand and type of speaker on the market as a FOH engineer and can honestly say I will never invest my money in any other brand. JBL continues to dominate the market. Looking forward to getting my new VRX tops, but sticking with the raw power and perfectly designed SRX subs.

  • This has got to be the best sub I've ever heard...

    As reviewed by adrian on 2/8/2007

    Recently I got two of these subs with another pair of SRX725's and they've got to be the best, most accurate subs I've ever heard. I tri-amped the system as to be more effeciant, and lows were crystal clear.
