One Knowles armature is tuned for clear upper mids that blend smoothly with the electrostatics; the other has a vented back chamber for fuller lower mids, which suits pop vocals. The four Sonion EST65QB02 electrostatics give an airy, open treble. A new RLC second-order band-stop filter removes resonance peaks from the drivers and shell, for a smooth treble that stays easy to listen to.\u003c\/p\u003e\n\u003ch3\u003eTuned shells\u003c\/h3\u003e\n\u003cp\u003eFiiO’s patented S.Turbo sound tube in the front chamber adds bass weight and punch and filters excess upper frequencies from the dynamic driver, and micro vents in the rear chamber balance the pressure for deeper bass and clear vocals.
