YL Acoustic D-5500
Price unknown (1 unit, release date unknown)
Commentary
Horn type tweeter developed for the mid-range of D series.
The D series is a series that uses plastic edges.
A thin polyester resin plate is attached to the edge with corrugating by heat molding. By installing the corrugating by heat pressing, edge squeal due to edge resonance is suppressed.
As with the 35 Series, the 55 Series is equipped with a vibration plate behind the magnet so that the sound can pass through the center of the magnet for rationalization.
Hard duralumin plate is used for the dome of the diaphragm.
