About the JBL S2-1224SS

You can switch this sub box's impedance from 2 ohms to 4 ohms.
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. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Features
Selectable Smart Impedance (SSI): A switch on the input terminal allows you to easily change the woofer's impedance between 2Ω and 4Ω settings. (The connected amplifier should be off when changing the impedance.)
Slipstream Port: The JBL S2-1224SS has a Slipstream port on the front of the enclosure. The double-flared shape of the oversized port is precisely calculated to efficiently eliminate port noise. Even at high SPL, airflow through the port will remain uniform, offering better low-frequency extension and woofer protection. Because the area of the port in the middle is smaller than the mouth of the port, the port can be much shorter than a cylindrical port with a surface area the same as the Slipstream port's mouth; this means it can fit into smaller boxes.
Binding Post: The wire terminal, on the right side of the enclosure, features a pair of binding posts that will accept single banana plugs, pin connectors, spade lugs, and bare wire up to 10-gauge.

Sub sounds awesome hits hard and loud. It won't shake the neighborhood but it's still hit hard enough to feel it. I have it paired with a Kenwood kac-5001ps mono block.
