    Legatia Speaker Design Considerations The Legatia-series component speakers are electrodynamic drivers that are comprised of a diaphragm (cone, or in the case of the Legatia L1V2 tweeter, a dome) that is set in motion by a motor system that has both electrical and mechanical components. For more details about the Stage V Legatia tweeter offering, the Legatia L1V2, please go to page 10.
