Based on the company’s prior Soulra sound system, the Soulra XL features an integrated 72 sq. in. solar panel for charging, a rechargeable lithium-ion battery pack good for up to five hours of playback, eight speaker drivers—two tweeters, two woofers, and four passive radiators—22 Watts of total output, rubberized end caps, an anti-glare tinted docking chamber, an included remote control with integrated storage, and a removable, gel-cushioned carrying strap. The Eton Soulra XL speaker system for iPod and iPhone is available for pre-order and is expected to ship later this month for $300.
