The Special Edition foxL (pronounced foxul) PLATINUM, defies conventional wisdom about sound - a miniature audiophile portable music system that turns the palm of your hand into a personal amphitheater; it provides enhanced performance features beyond even the award-winning foxLv2 Bluetooth model. Wall or battery powered. Wired or wireless. For phones/ipod/mp3 players, laptops, mobile gaming, and more. Soundmatters' foxLv2 Bluetooth is the first and only pocket-sized portable loudspeaker for audio purists - now with great sounding wireless music streaming for Macs, iPhone and iPod touch. It also has a built-in microphone for business-quality hands-free operation to take phone calls on. To achieve audiophile-approved sound quality and its remarkable 8-octave bandwidth, the tiny foxL utilizes highly advanced speaker technologies found nowhere else, regardless of size or price. Additionally, the Platinum edition add CSR's aptX Bluetooth codec for On-board amplification is supplied by four ultra high-efficiency digital amplifiers delivering total power up to 8W at < 0.1%THD. Unlike other portable speaker systems, foxL engineered around a pair of proprietary, highly sophisticated acoustic drivers, unique in their ability to reproduce both extreme high (tweeter) and low (woofer) frequencies from a single very small diameter (25mm) dome speaker, dubbed the""Twoofer"".
