- 1 250W subwoofer- Owners Manual- Technical data sheet

JBL latest Club subwoofers offer incredible installation flexibility. Their low-profile design allows them to fit perfectly into even the most shallow of enclosures great for todays compact cars. Polypropylene woofer cones deliver exceptional bass response at frequencies as low as 27Hz. But what makes these subs really stand out is their Harman-proprietary SSITM (Selectable Smart Impedance), which allows the subwoofer to present the amplifier with either a 2 or 4 ohm load at the flip of a switch. Low-Profile Design Because todays compact cars offer less space, the JBL Club Subwoofers are designed to fit into small enclosures. Theyre slim, sleek, stylish, and dont 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, youre not always hearing them all. With lows that dig down into the depths of 27Hz, youll hear the low-end frequencies youve been missing.
