Infinity Reference Series 103WSL 10" Shallow Mount Subwoofer 1050W 2/4-Ohm Selectable Impedance SSI

INFINITY REFERENCE SERIES: DEEP BASS, SHALLOW FIT

Upgrade your vehicle’s audio experience with the Infinity Reference 103WSL. This isn't just a subwoofer; it’s a high-performance solution for modern car interiors. Engineered with an ultra-slim profile, it delivers the signature Infinity deep bass you crave without sacrificing precious cabin space.

VERSATILE SYSTEM CONFIGURATIONS:

Under-Seat Stealth: The 3-1/4" mounting depth makes it ideal for compact enclosures under the seats of many pickup trucks and SUVs.

Slim Trunk Enclosures: Perfect for shallow-mount boxes that leave room for your gear in today’s compact cars.

Selectable Impedance (SSI™): Easily switch between 2-ohm and 4-ohm loads at the flip of a switch, allowing you to reconfigure your system without buying a new subwoofer.

OEM Integration: A premium choice for replacing factory subwoofers in shallow locations while providing a massive boost in low-frequency impact.

Multi-Sub Setup: Low-profile design allows for dual-subwoofer configurations in tight spaces for double the bass output.

KEY FEATURES:

Patented SSI™ (Selectable Smart Impedance): Features a unique dual-impedance switch that lets you choose 2 or 4 ohms. Switching to 2 ohms allows you to "unlock" the maximum power of your amplifier (as most amps deliver higher wattage at lower impedance), giving you harder-hitting bass without needing a more expensive amplifier.

Slim Design Profile: Specifically engineered for "shallow-mount" applications where traditional bulky subwoofers simply won't fit.

Proprietary Aluminum Cone: Engineered to provide high output while maintaining its shape at full excursion to ensure low distortion and musical impact.

High-Roll Rubber Surround: Provides superior cone edge suspension while maximizing excursion for deeper, more powerful bass.

Harman Standard Reliability Testing: Every Infinity speaker undergoes environmental testing that would destroy most speakers—freezing, baking, and shaking—to ensure it lasts a lifetime in your car.
