So, how much power? Well, the company says 20w. Since a USB port can only provide 5V/0.5A of power, regular speakers usually offer just 0.5W per channel. But Yamaha has developed the “Charged Capacitor Amplifier”, so it can throw out 10x the normal power – 10W x 2. And to boost the sound even more, Yamaha’s SR-Bass technology reproduces “the deepest bass ever” in relation to the size of speaker.
The NX-U10 also offers battery operation if you are out and about, with an additional 3.5mm input jack to enable your phone, iPod, MP3 and or analogue source to connect too. Available in the early part of 2007, priced at £149.
