Amplifier manufacturers are building amps that can produce more power at less cost than ever before. The SRX700 series lets you unleash that power with a new generation of high-power low-frequency drivers. That would be enough for most manufacturers, but JBL accomplished this while also greatly reducing the weight of the drivers.
SRX700 uses JBLs patented Differential Drive woofers with neodymium magnets. Neodymium's magnetic properties allow a few ounces to replace pounds of conventional magnet material. While other speaker manufacturers may use neodymium, JBL engineers created a design that reduces the massive (and heavy) steel top plates, back plates, and pole pieces that complete the magnetic circuit. The JBL Differential Drive design uses two voice-coils for greater power handling and actually puts the small neodymium magnets inside the voice-coil. This design greatly reduces weight while increasing power capacity, decreasing distortion, and reducing power compression.
SRX728S Dual 18" subwoofer
The SRX728S is built to deliver smooth, clean, accurate low-end. A pair of 18"Differential Drive woofers provide extension down to 27 Hz while handling anamazing 1600 watts of continuous power. Large, open ducts minimize portturbulence and the heavily braced enclosure assures tight, solid bass. An externalswitch allows the SRX728S to be used with cabling systems designed to powersubs from contacts 1 or 2.
