A space frame reinforced tweeter dome is disclosed. The tweeter dome includes a space frame and a convex diaphragm attached to the space frame. The space frame can include a crown portion in the form of a triangular frame and three leg portions each extending from a corresponding vertex of the triangular frame. Each leg portion has a distal foot adapted for connection to a voice coil former for movement therewith. The convex diaphragm can be comprised of a soft, e.g., textile, material while the space frame is comprised of rigid material such as metal. The space frame reinforced tweeter dome is free from ringing while being sufficiently rigid to follow the enormous accelerations of a music signal at high frequencies.
