JBL Club WS1200 (CLUB series) slim subwoofer 12" (300 mm).

Low-Profile Design
Because today’s compact cars offer less space, the JBL Club Subwoofers are designed to fit into small enclosures.
They’re slim, sleek, stylish, and don’t sacrifice on sound.
Harman-Proprietary SSITM (Selectable Smart Impedance)
Unlike most dual-voice coil woofers, which provide either 1 or 4 ohms or 2 or 8 ohms, the JBL Club
Subwoofers allow the listener to 2-ohm and 4-ohm at the flip of a switch, providing the two most often used impedances from a single woofer.
This allows the system designer unparalleled flexibility in extracting every last watt from your amplifier without compromising stability and thermal safety margins.
Frequency Response As Low as to 27Hz
Your audio is filled with delicious sounds. Unfortunately, you’re not always hearing them all.
With lows that dig down into the depths of 27Hz, you’ll hear the low-end frequencies you’ve been missing.

Power handling, continuous average - 250 W.
Nominal impedance 2 ohm or 4 ohm, switch selectable.
