Description
Infinity Kappa 123WDSSI
The Infinity Kappa 123WDSSI is a high‑performance 12″ component car subwoofer engineered to deliver deep, powerful bass with versatile impedance options for system flexibility. It features SSI™ (Selectable Smart Impedance) technology, allowing you to switch between 2 Ω or 4 Ω final impedance to better match your amplifier and audio setup. The subwoofer uses a Plus One™ glass fiber cone with high‑roll rubber surround for increased cone area, strong low‑frequency response, and greater excursion. It also includes a vented basket design for better cooling under high output and durable performance. With 400 W RMS and 1200 W peak power handling, 84 dB sensitivity, and a frequency response from approximately 30 Hz – 500 Hz, the Kappa 123WDSSI delivers impactful, deep bass suitable for sealed or ported enclosure applications in high‑performance car audio systems.

About The Product
Take Infinity car audio for a ride. Innovative materials and breakthrough engineering have always placed Infinity products in front of the competition. You can expect extreme output from Kappa subs, so be prepared for accuracy and detail that will simply blow you away. The Kappa Series subwoofers feature SSI™ (Selectable Smart Impedance), a HARMAN-exclusive impedance selector that lets you choose a 2- or 4-ohm impedance at the flip of a switch. Our proprietary aero-cooling design keeps the voice coil cool while optimizing power handling and long-term reliability. Finally, the acoustically damped glass-fiber cones have been engineered to minimize distortion and unwanted artifacts. More performance and flexibility: you get both when you step up to an Infinity Kappa subwoofer.
