The Grande Castine horn speakers are the brainchild of Musique Concrete, which means "real music" in French. The unusual contraption should appeal to audiophiles with its deep bass response down to 20Hz, thanks to a sizable 38cm woofer and an efficient horn design. Covering the other end of the spectrum is a 50mm midrange driver and a 25mm tweeter, allowing the Grande Castine to achieve a full 20kHz response. What's more, the speakers' high 106dB sensitivity means they can effortlessly play back soulful tunes utilizing lower-wattage amplifiers, unlike most large and power-hungry speakers.
You can catch the Grande Castine in action at the High End 2011 exhibition in Munich from May 19 to 22, but expect these exotic speakers to cost somewhere around $100,000.
