      This driver is in the absolute top range of midrange drivers. Very high sensitivity, high SPL and smooth frequency range. Easy to integrate, very low THD. Why only 4 stars? I directly compared to the Aluminium version and the silk driver is more "gentle" and softens the sound a little. It brings a sound by itself which means it's not as honest as the metal driver. (e.g. Crash cymbals sound less "explosive" and metal as they are) This can be the perfect sound for enjoing music and NOT hear every little mistake happend during recording/performance! But I want precision in the midrange when useing a dome driver - so I will use the A or B version for my projects. (This sound of the driver is "designed" from Bliesma and wanted so people have choices. The dome is relatively soft, the classic ATC driver is more stable as I remember)
