Features and Benefits
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.
