Reference audio system of Miyajima-Lab

This photo is the audio system of Miyajima Laboraory recently.

This audio system divides the frequency into four.
Ultra low frequency, low frequency, medium frequency, high frequency.
Ultra low frequency is outputting 50 Hz or less by an independent power amplifier.
Low frequency and medium frequency are separated by LC channel divider.
Low frequency is 50 Hz - 300 Hz.
Medium frequency and high frequency are separated by network.
Medium frequency is 300 Hz - 5,000 Hz (10,000 Hz). (WE 555 and Carl Horn)
It is the best system that Miyajima-lab thought.
All speaker units excluding high frequencies are of excitation type.
MC amplifier, preamplifier, all three power amplifiers are composed of vacuum tubes.

Below is the details of the contents.
