CANTON CA30N
¥ 1,400,000 (1 unit, around the early 1990 s?)
Commentary
Active speaker system with a 4-way 7-speaker configuration driven by a total of 7 internal amplifiers.
The CA30N uses the MFB method, and the magnetic sensor (Hall element) is connected to the cone paper of the woofer. The voltage corresponding to the movement of the cone paper is obtained from the Hall element, and this voltage is fed back to the amplifier to control the movement of the cone paper, and delay in the rise and over / under shoot are improved.
Four 26 cm cone type woofers are driven in parallel for the lower range.
In addition, the speaker vibration system is incorporated into the NFB loop of the amplifier in an MFB (motional feedback) system, eliminating distortion in the ultra-low frequency range.
It has a 19 cm cone type midbus in the middle and low range.
The mid-range is equipped with a 3.8 cm hard-dome squaker, and the high-range is equipped with a 2.5 cm hard-dome tweeter.
All units are driven by seven independent module amplifiers with two power supply modules at each end.
The exterior has a mahogany finish.
