JBL SRX728S at a Glance:

• Passive 2 x 18" subwoofer with 1600-watt power handling
  
• Built Tough for the Road

Plenty of Power
The SRX728S is built to deliver smooth, clean, accurate low-end. A pair of 18" Differential Drive woofers provide extension down to 27Hz while handling an amazing 1600 watts of continuous power. Large, open ducts minimize port turbulance and the heavily braced enclosure assures tight, solid bass. An external switch allows the SRX728S to be used with cabling systems designed to power subs from contacts ±1 or ±2.

Built Tough for the Road
All SR-X enclosures are constructed of 13-ply void-free baltic birch. The result is a solid enclosure free from resonances…What you hear is the speaker system, not the box. All SR-X Series enclosures are finished in JBL's tough DuraFlex finish, which shrugs off the inevitable scuffs and dings. A non-resonant, full-length grill provides protection for the components and a rich yet unobtrusive appearance. No matter how rigorous your tour schedule, the SRX728S will take the abuse and perform night after night.

Since its inception in 1927, the name JBL has been associated with excellence, innovation, and superior sound quality. That's why Leo Fender saw JBL's D130 as the ideal speaker for his guitar amps. Continuing to define the sound of rock, JBL also became the sound of Woodstock and other major rock festivals. JBL's speakers are held to the most rigorous standards in the industry, and audio professionals worldwide rely on them for that reason. JBL studio monitors were ranked first in a U.S. recording industry survey by Billboard.
