Already own the original “White Cone”? Avantone can keep them running for years. Since Yamaha® discontinued the iconic NS10M, the supply of aftermarket components has become more and more expensive and less and less available. Avantone Pro has done an exact reverse engineering of the original drivers. Using our global resources and decade of experience in driver construction, we have reproduced the components faithfully, while upgrading components for longer life, and updating materials to comply with environmental requirements. Black box. White cone. High-range frequency. It’s not known as the world’s best — it’s known for being the world’s best reference — the sound that creates hits. Replacement Woofer for CLA-10 / NS-10M The Low Frequency driver, AV10 MLF, is a near exact match from 20Hz to the crossover frequency. We have changed the cone design from a lapped seam to a single continuous press formed cone from the same supplier as the original. This allows a much higher level of quality control and consistency during the manufacturing process. The AV10 MLF replacement driver is physically and dimensionally exactly the same as the original and is a “bolt in” hassle free install that requires no changes to the cabinet in the installation process.
