From Our Research Team:

Big Low-end from JBL!

The new SR-X Series was designed for these most discerning users, with 11 models that embody the superior engineering, unsurpassed tour sound performance, legendary reliability and value inherent in the JBL name. Start with the SR-X's advanced DuraFlex finish. Add their all-new networks. Top them off with the same components found in 9 out of 10 speaker systems on the road with today's top touring acts. All wrapped up in a speaker whose lineage is connected by a solid line of leadership more than half a century long. While each SR-X speaker has a personality all its own, the line as a whole delivers a remarkable range of options. In fact, the SR-X line is the most complete line of high performance portable speakers available today, with a model for virtually every application. Whether your needs call for SR-X subwoofers, SR-X front-of-house systems or SR-X stage monitors, you can be assured of owning a speaker that represents a new standard; a standard that will satisfy even the toughest of critics.


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.


JBL SRX728S Features:
  • The JBL SRK728S is a dual 18", 2-way, bass-reflex, subwoofer
  • Frequency Range (-10 dB): 27 Hz - 220 Hz
  • Frequency Response (±3 dB): 33 Hz - 220 kHz
  • Power Rating (Continuous/Program/Peak): 1600 W / 3200 W / 6400 W
  • Dimensions (H x W x D): 24 in. x 42 in x 33 in
  • Net Weight: 166.5 lbs.

The JBL SRX728S subwoofer delivers smooth, clean, accurate low-end with power-handling to spare!

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.

Lotsa low end

I've owned these subs for almost a year now and the range and quality of sound is phenomenal! It takes two people to effectively move it, but the handles make that chore fairly easy. I run a bridged... read more [+] Crown XTi 4000 and a DBX Driverack PA+ and I've never had a problem. My only gripe is it's not carpeted. The paint will scratch if you drag or ding it... JBL, put some carpeting on this sucker...or maybe some rhino lining! close [-]

Great sub but not D and B

Great sub. Work at a church running sound for youth. I have two of these bridged off of 2 crown Xti 4000 amps run through custom eq. They hit very hard! I have experence with EAW, D and B, L Acust... read more [+]ics, Yahama, mackie, comunity, sound bridge, qsc, ev and Tom danly labs. I also have run 2 SRX subs the older model (like the old porting better). I also own the SRX 718s subs......What to say SRX728s are better then running two 718s side by side. They are cleaner bc the porting is larger. I would say hands down they are better then yahama, comunity, mackie. EV and sound bridge. I agree with are local perfessional rodie friends that they allso out do EAW. Jbl is a great box on a budget. they dont get close to d and b, L acustics, or Tom danily but for the money they are great. these other boxes are like 4 grand each. For are churchs loud style of music (100+db) two of these cover 400 ish people in a 500 seat youth room. We do like are bass to hit you in the chest. Never had any problems with hadware of cones. wish there was pre set holes for weals like on the 718s box. hope this helps close [-]

My experience was outstanding! I feel like I'm back in the 1950's when customer service was worth its weight in gold! I love the candy and personal phone call to acknowledge my order. You deliver the goods with superior efficiency, expediency and true concern for the customer.
