New ideas

When you're looking for a new subwoofer, you want deep, rich bass. Sony's Mobile ES Series XS-W104ES 10" sub is engineered from top to bottom with proprietary Sony technology to deliver low frequencies at high volume levels with minimal distortion, so you'll get the best bass possible.

Into the cone zone

The XS-W104ES features a Mica Reinforced Cellular (MRC) cone, created for high rigidity, light weight and good internal loss. 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 that uses 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.

If you're looking for superior low-frequency punch, this unique Mobile ES sub uses proprietary materials and creative design to bring high-performance bass to your ride and give you the gift of great sound.
