Here is one of two copper woofer inductors that are used for a pair of new VAF Signature i66 MKV's, wound in-house from heavy gauge 2mm pure copper wire, and weighing a whopping 3.5 kg.
Why use such a hefty inductor? Ultra low DC resistance. This provides several benefits - better power transfer, better damping and power handling with more dynamic headroom, along with better thermal stability. Being an air cored inductor, the thicker wire avoids magnetic core saturation and results in lower distortion. It also doesn't alter the woofer's Q, which leads to more accurate, predictable and consistent crossover simulation during the design process.
All of this purposeful, thoughtful design for an internal component that 99.9% of purchasers will never see, or even know is there.
