Totally dustproof Developed by Sony, the X-Balanced Speaker Unit achieves high sound quality and powerful sound pressure for a richer, deeper, more rewarding listening experience.

Built to last Unlike the circular diaphragm in a conventional speaker unit, the newly developed X-Balanced Speaker Unit in the XB33 features a non-circular diaphragm.

Long battery life The unit's non-circular shape not only maximizes the area of speaker diaphragm, increasing sound pressure for more punchy bass-it also reduces driver excursion while maintaining the same sound pressure, resulting in less distortion.

What is the X-Balanced Speaker Unit" The rigid and lightweight Mica Reinforced Cellular (MRC) speaker cone and dust cap contributes to the sound quality.

Increasing sound pressure and reducing distortion The layout of the side passive radiators has been optimized to reproduce clear bass sound.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
