Duke is a sexy high-end speaker that created ripples at the CES. Designed by Trenner & Friedl, the Duke speaker system has a Swarovski-crystal “disperser” for a 360-degree radiation effect. It features two 12-inch “fiberglass-reinforced paper-cone woofers” and uses the damping material, which is hand-felted sheep wool. The five feet tall and 284 pounds Duke has frequency range ranges from to 80kHz (-3dB) with a sensitivity of 92dB/W/m. And, it sounds superb! However, what’s most thrilling is its price tag, which stands at staggering $175,000.
