Sound you can feel - like the roar of a powerful engine. Audio inspired by the colors and design of Yamaha Motorcycles. Revved up and ready to go. A feeling of freedom like riding your motorcycle on the open road - without leaving home. Add a new color to your daily routine with the unique MCR-B043D. Choose your color and get more out of your music. From the top panel ornamentation recalling an engine fan to the volume knob echoing the design of a radiator cap, the inspiration behind Yamaha motorcycles shines through. The dark grey color features the distinctive racing stripe that evokes the speed of a motorcycle. Yamaha Motor's vision is fully realized by this sleek and stylish speaker. Enjoy wireless playback from your smartphone, tablet or PC effortlessly with Bluetooth technology. In addition to the CD player, USB and DAB/FM radio, it has an AUX-In terminal for connecting a PC or Digital Audio Player, giving you music enjoyment from a variety of sources in one unit. An onboard USB port allows you to charge your smartphone or tablet too. The MCR-B043D includes Yamaha's Music Enhancer that restores what is lost when audio data is compressed (as in a Digital Audio Player) to deliver sound that is more dynamic and has a greater feeling of expansiveness. What's more, the speakers feature an 11cm (4-1/2") drive unit that uses a large-diameter magnet to deliver rich bass, clear mids and sparkling highs. The large-volume cabinet acts like a bass drum, further helping to produce deep and robust bass.
