JBL 12″ Dvc 1100w subwoofer S21224

JBL Series II 12″ component loudspeaker with switchable 2- or 4-ohm impedance

Selectable impedance

JBL’s Series II S2-1224 sports a 2” diameter voice coil for exceptional power handling, while airflow from the cone’s movement cools the voice coil for increased reliability. The sub’s Selectable Smart Impedance (SSI™) switch allows you to change impedance from 2 ohms to 4 ohms, so you can optimize the sub for your system and the amplifier. This feature makes it easy to reconfigure your system when you add another Series II subwoofer or upgrade your amplifier.

This sub features a polypropylene cone for enhanced stiffness and an nitrile rubber surround for additional smoothness and responsiveness, while the stamped steel basket adds rigidity and its vented construction helps keep things cool. The S2-1224 handles up to 275 watts RMS (1100 watts peak), and works equally well in sealed or ported enclosures, another example of its versatility.
