Commentary
SG-17 series horn type tweeter unit.
The horn section consists of a circular aluminum bar hollowed out into a hyperbolic curve and is integrated with the driver. This horn provides a complete horn load horn load on the diaphragm and evenly applies the air impedance to all frequencies.
Type A has a modified horn with a cutoff frequency of 2.5 kHz.
Uses Mylar (FRP) edge.
The voice coil uses an edgewise wound voice coil made of aluminum ribbon wire.
An external magnetic ring magnet is used for the magnetic circuit.
