Infinity Reference 123WSL

The Infinity Reference 123WSL is a 12″ shallow‑mount component subwoofer engineered to deliver deep, powerful bass while fitting easily into installations with limited depth. It features SSI™ (Selectable Smart Impedance), allowing you to switch between 2 Ω and 4 Ω to best match your amplifier and audio setup. The subwoofer uses a proprietary aluminum woofer cone with high‑roll rubber surrounds for strong low‑frequency output and maximum cone excursion, paired with a vented basket design that keeps the voice coil cool during high‑power use. With 400 W RMS and 1200 W peak power handling, 84 dB sensitivity, and a frequency response of approximately 30 Hz – 500 Hz, the Reference 123WSL delivers impactful, accurate bass performance without sacrificing space. Its shallow mount design (about 3¼″ mounting depth) makes it ideal for tight installations such as under seats or compact enclosures.
