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

INFINITY REFERENCE SERIES: UNCOMPROMISED BASS PERFORMANCE

Upgrade your car’s audio with the Infinity Reference 103W. Part of the newly redesigned Reference Series, this 10-inch component subwoofer is built to deliver deep, powerful, and accurate low-end frequencies that transform your daily drive into a concert-level experience.

VERSATILE SYSTEM CONFIGURATIONS:

Precision Sealed Enclosures: Optimized for 1.02 ft³ sealed boxes to provide the most accurate sonic reproduction for all music types.

High-Efficiency Vented Setup: Ideal for ported enclosures when you want maximum bass output from a smaller amplifier.

Selectable Impedance (SSI™): The exclusive dual-impedance switch allows you to toggle between 2-ohm and 4-ohm loads instantly—perfect for system reconfigurations.

Free-Air Compatibility: Can be mounted to a baffle board (infinite baffle) for unique installation needs (note: power handling is halved in this setup).

Multi-Sub Integration: The flexible SSI technology makes it simple to wire multiple 103W units together while maintaining the ideal load for your amplifier.

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, providing harder-hitting bass without the cost of a larger amp.

Double-Stacked Magnet: Equipped with a massive magnet structure that allows the voice coil to travel over a longer excursion for bigger power handling and deeper bass.

Vented Basket Design: The basket is specifically engineered to keep the voice coil cool even at high output levels, ensuring long-term reliability and consistent performance.

High-Roll Rubber Surround: Provides superior cone edge suspension while maximizing excursion and linear stability.

Harman Standard Reliability Testing: Subjected to extreme freezing, baking, and shaking tests to ensure your investment lasts for years under the harshest car environments.
