The ceramic-coated aluminium dome ensures a balanced frequency response and superb transient behaviour for a uniquely realistic soundstage. Its compact aluminium housing with integrated grille protects the delicate dome, while the high-efficiency neodymium magnet guarantees linear magnetic flux. The FlexMount25 system uses bespoke adapter rings to transform this universal tweeter into a vehicle-specific solution, allowing seamless installation in original mounting positions.
