The estimated market price is 258,000 yen including tax. The model is built around a newly developed True Magnesium diaphragm and replaces the beryllium driver of the 2019 A8000, which final says became difficult to manufacture because of material procurement. Final says all parts are newly designed and selected.","whyItMatters":"Final is rebuilding its flagship around magnesium because the beryllium supply that defined the 2019 A8000 ran out, so the successor carries both the old tuning goal and a new material problem to solve.","webCardHtml":"\u003cp\u003eThe A8000 DC exists because True Beryllium stopped being procurable. Final discontinued the 2019 A8000 when the material became difficult to continue manufacturing, and the replacement cones seven years later with a diaphragm it calls True Magnesium.\u003c/p\u003e\u003cp\u003eMagnesium does not match beryllium on resistance to deformation, and final says so directly. The argument for it is weight: about two-thirds that of aluminum, which allows a thicker diaphragm, and bending rigidity rises with the cube of plate thickness. A proprietary alloying treatment addresses pure magnesium\u0026#39;s strength problem, and a polyurethane edge carried over from the A10000 development targets divided vibration.\u003c/p\u003e","blueskyPost":"Final's A8000 DC arrives October 30 at 258,000 yen.
