You want deep, rich bass. Sony's unique Mobile ES Series XS-W122ES 12" sub uses proprietary materials and creative design to bring high-performance bass to your ride and give you the gift of great sound.
Into the cone zone
The XS-W122ES features a Mica Reinforced Cellular (MRC) cone, created for high rigidity and light weight. This material combines a layer of mica flakes and paper pulp with a honeycomb-shaped aramid fiber core, for a speaker cone that's 10 times stronger than polypropylene. You'll hear cleaner, more realistic bass with smoother, more natural sound characteristics, along with powerful bass that stays tight at the highest volume levels. In short, this sub is all about accuracy.
Intelligent design
The woofer surround features another proprietary Sony technology — distinctive curved notches to ensure that the cone stays on track. The acoustically-optimized double-layered spider maximizes power handling, with a profile designed for more rapid and precise cushioning of the speaker cone. The sub's "Five-beam Frame" design virtually eliminates resonance, while its integrated Dynamic Air Diffuser ensures efficient air circulation to keep things cool when the music gets hot.
