Infinity Subwoofer Reference 103WSL

Bass Without Compromise

Compact cars shouldn’t mean compact sound. The Infinity Reference INFSUBRF103WSL 10″ Shallow-Mount Subwoofer is engineered to deliver the deep, resonant bass you crave—even when space is limited. With response that dives down to 35 Hz, every beat and every note gets the weight it deserves.

Why It Matters

• Selectable Smart Impedance (SSI): Switch easily between 2 or 4 ohms for maximum flexibility with your amp setup—no messy wiring required.

• Shallow-Mount Design: At only 3.25″ top-mount depth, it fits where traditional subs can’t—perfect for today’s slim enclosures.

• Engineered for Power: Handles 350W RMS (1050W peak) with stability, efficiency, and thermal safety.

• Premium Build: Aluminum cone reinforced with radial design + high-roll rubber surround = deep excursion and distortion-free bass.

• Proven Reliability: Infinity puts every subwoofer through extreme freeze, bake, shake, and UV tests to ensure long-lasting performance.

The Experience

Forget flat, lifeless sound. With Infinity’s Reference Series, you don’t just hear the bass—you feel it. The 103WSL brings stadium-level depth into your cabin, no matter how compact your car. Smooth integration, clean design, and a trim ring that hides the hardware make it look as good as it sounds.
