JBL SRX728S

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 an
amazing 1600 watts of continuous power. Large, open ducts minimize port
turbulence 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.
