SSI™ (Selectable Smart Impedance)
Most car audio system designs call for 2- or 4-ohm impedance. Reference subwoofers feature an exclusive dual impedance switch that lets you choose either load impedance option. Not available from any other manufacturer, SSI lets you reconfigure your system by simply flipping a switch.
High-roll surround
Reference woofers incorporate a high-roll surround that provides superior cone edge suspension while maximizing excursion. It not only increases the cone area, it also provides remarkable linear stability and reliability.
Proprietary cone design
Infinity subwoofer cones aren’t just built to thump, they’re built to last. Reference woofers feature an exclusive cone design that delivers superior rigidity for long-lasting performance.
Long excursion design
The longer a subwoofer’s excursion is, the more air it moves. And the more air it moves, the more bass you feel. The long-excursion design in Reference subwoofer ensures big, deep bass output. Just the way you like it.
