SSI™ (Selectable Smart Impedance)
Stadium subwoofers feature an exclusive dual impedance switch that lets you choose either load impedance option. This allows for a variety of system configurations when using one subwoofer or multiples. 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.

Features:
- Selectable Smart Impedance (SSI): A switch on the input terminal allows you to easily change the woofer's impedance between 2Ω and 4Ω settings. (The connected amplifier should be off when changing the impedance.) The power handling is the same for either setting; 275 watts RMS/1100 watts peak.
- Sealed Box Volume: 0.75 ft³
- Ported Box Volume: 2.5 ft³ with one 4" diameter x 11.7" long port (tuned to 30 Hz)
- Free-Air: The woofer can also be mounted in free air to a baffle board (infinite baffle, no enclosure). When mounted in free air, the power handling is reduced by half (to 137-1/2 watts RMS).
- Band-Pass: Infinity also recommends a prefabricated band-pass enclosure, but no volume specifications are listed in the manual. Band-pass enclosures often provide the most output available from any amplifier and subwoofer combination, but at the expense of sonic accuracy.
