Ruthenium* plating is used, renowned for its resistance to deterioration over time and its sound quality.
Ruthenium, known for its high hardness, abrasion resistance, heat resistance, and corrosion resistance, is used to plate the speaker,
resisting deterioration over time and enabling long-term use inside the car.
*A type of precious metal also classified as a platinum group metal. Platinum group metals are a collective term for six metals—platinum, palladium, rhodium, ruthenium, iridium, and osmium—that are mined together as minerals and share common properties. Ruthenium has a silvery-white appearance and is a hard, brittle metal. However, like palladium, it has the ability to absorb large amounts of gases (such as hydrogen and nitrogen). Adding ruthenium to other platinum group metals creates a high-hardness alloy. It is primarily used in electrical, catalytic, and electrochemical applications. It is obtained as a by-product of the platinum ore smelting process, but its trace amounts make it a rare metal.
█ Three-layer coating for vibrant, expansive sound quality
A three-layer coating consisting of copper underplating, gold flash plating, and ruthenium plating.
The gold flash plating underneath the ruthenium plating suppresses harsh, harsh sounds and produces a smooth high range and expansive mid- and low-range sounds.
