Wider sound with Line-Shape Diffuser X-Balanced Speaker Unit for powerful and clear sound IP67 water resistant and dustproof 16-hours of battery life and quick charging Strap for comfortable portability Product Highlights Better sound all around : The XE200 has a Line-Shape Diffuser that will help your music reach further, even to the side of the speaker. Plus, with a portable size and handy carry strap, you can take it anywhere you go with ease. Introducing the Line-Shape Diffuser : Inspired by the audio systems used at professional concerts, Sony's unique Line-Shape Diffuser creates line source and distributes the sound energy much more evenly, across a wide sound front, to better fill your venue with audio. This spreads high-quality sound further and wider around your venue, without compromising on sound quality. What the Line-Shape Diffuser does : With the Line-Shape Diffuser, the sound spreads further to the front area of the speaker allowing you to enjoy the same sound quality whether you are at the front or to the side of the speaker. This means that everyone in your venue can dance to the same music feeling the same sound quality. A=Conventional Service Area B=Wider Service Area with Line-Shape Diffuser How it works : Unlike a conventional speaker, with most of the energy focused from the center of the cone, our unique Line-Shape Diffuser refocuses the sound through a narrow aperture. The increase in sound pressure energy spreads the audio equally in each direction both further and wider out from the speaker. What is the X-Balanced Speaker Unit? : Unlike the circular diaphragm in a conventional speaker unit, the newly developed X-Balanced Speaker Unit in the XE300 features a non-circular diaphragm which realises more sound pressure for a high-quality sound.
