GOTO UNIT SG-17S/A |
49,800yen
(One set. It put on the market in February, 1978 and afterwards. ) |
The horn type tweeter unit of SG-17 series.
The horn part is a hyperbolic curve with the hole-was-made structure about
the aluminum round bar, and is united with the driver. By this horn, the
perfect horn loading started the diaphragm and the air impedance is uniformly
applied to all the frequencies.
Moreover, by A type, the horn is changed and the
cut-off frequency has become 2.5kHz.
The Mylar (FRP) edge is adopted.
The edgewise volume voice coil which used the aluminum ribbon line is
adopted as a voice coil.
The ring magnet of a Ferrite type is adopted as
a magnetic circuit.
