About: Infinity Reference INFSUBRF103WSL 10" 350W RMS Shallow-Mount Component Subwoofer 

Today's compact cars offer less space for a component subwoofer, but Infinity doesn't want you to miss out on the bass you deserve. They designed the Reference Series 103WSL 10" subwoofer to fit into today's smaller enclosures without sacrificing on sound. With response that goes down to 35 Hz, you'll definitely hear the low frequencies you've been missing.

Selectable impedance

Unlike most dual-voice coil woofers which require complicated wiring schemes for different impedances, this Infinity sub features an SSI (Selectable Smart Impedance) switch that flips between 2 and 4 ohms, the most commonly used settings for a single sub. You'll be able to extract every last watt from your amplifier without compromising stability and thermal safety margins.

Standout design

The 123WSL features an aluminum cone with a unique radial pattern reinforced cone that keeps its shape at high output levels, plus a high-roll rubber surround that allows maximum excursion while keeping the cone stable. The vented basket optimizes airflow to keep the 2" voice coil cool. A gloss black trim ring press-fits into place and conceals the mounting hardware for a clean, professional look.

Reliability testing

Infinity tests every model under extreme conditions that would break lesser speakers. They 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. Get ready for big bass in a small space.
