Infinity’s latest Reference subwoofers offer incredible installation flexibility. Their low-profile design allows them to fit perfectly into even the most shallow of enclosures — great for today’s 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 today’s compact cars offer less space, the Infinity Reference 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 Infinity Reference 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.

OEM-Level Reliability Testing

Infinity tests every speaker design to the same rigid specifications as the automakers, subjecting them to extreme conditions that would break lesser speakers. We freeze them, bake them, shake them, blast them with ultraviolet light and drive them at full power for days to make sure your audio investment lasts for years.
