DB11的7寸中音也是碳纤维盆吧
“Kharma’s remarkable Omega 7 driver is the heart (and soul) of the speaker. It is the brainchild of Charles van Oosterum, designer and Kharma CEO who has long been known for his pioneering work with ceramic drivers (he was the first to employ them in reference-quality loudspeakers). With the Omega 7, Charles said he was looking for higher reliability than ceramic cones provide, so he initiated a long-term development project to create a better cone, starting from a proverbial blank slate. He wanted a driver of optimized shape with great stiffness, transient quickness, and no audible resonances. Instead of utilizing a carbon-fiber sandwich for the diaphragm, Charles eventually decided upon a midrange cone made of strands of the highest-quality, strongest carbon fiber available. According to van Oosterum, this approach was “much more costly but led to less smearing.” The shape of the Omega 7 was optimized using finite element analysis, resulting in a driver with “near-perfect behavior.”
What distinguishes the Kharma S Series is the quality of the ultra-high-grade carbon fiber—a rare material only found in some of the more exotic Formula One race cars that is reportedly stronger, less resonant, and lighter in weight than any comparable fiber on the market. It is “the closest you can get to a pure diamond [driver],” according to Charles. The S Series also uses ultra-pure silver wiring throughout, and my local Kharma dealer, Michael Woods of Elite Audio Systems, told me that Charles evaluated more than 200 different samples of silver cable before selecting the one he liked best for the dB11-S. (Kharma also offers its own pure silver cables and interconnects, using the same silver conductors.)”
