No storm in this port
The Series II subwoofers were a big hit, so now JBL brings you their Series II bass enclosures, the perfect marriage of subwoofer performance and box design.The S2-1224SS enclosure comes loaded with JBL’s S2-1224 12″ subwoofer, which features a polypropylene cone and nitrile rubber surround made to stand up to life in an automobile. JBL’s patented Slipstream port uses a double-flared design to cut port noise and distortion by reducing turbulence. Less turbulence, more boom. This port allows JBL to design a smaller enclosure without sacrificing any impact.
Switchable impedance
The sub also features JBL’s Selectable Smart Impedance, which allows you to switch between 2 ohms and 4 ohms impedance to optimize the speaker to your system. This also allows you to start your system with a single Series II enclosure, then add another one later without having to replace your bass amp.
To drive this single subwoofer, we recommend a mono amplifier rated between 200 and 375 watts RMS at 2 ohms.
