The hybrid speaker uses a CLS electrostatic treble/midrange driver on a new ultra-rigid aluminum frame "AirFrame Blade", and the dynamic woofer section is equipped with two 200 mm drivers. The key feature is the integration of a new type of crossover speaker into the architecture, which brilliantly copes with the task of accurately distributing the signal between different types of drivers.
