CORAL BL-3
¥ 19,000 (1 unit, around mid 1970 s?)
Commentary
This speaker system was developed as a model with the advantages of back-loading type such as BL-20D and BL-25D, and bookshelf type which is relatively small and economical.
16 cm double cone type unit has been adopted.
The subcone paper, which is responsible for the high sound range, is made of high-density pulp with a special treatment. In addition, a sound-absorbing material made of synthetic fiber is placed on the back side to prevent interference with the main cone paper.
In addition, a ceramic magnet of 110 φ x60 φ x15t is used for the magnetic circuit, and a magnetic flux density of 13000 Gauss is obtained.
The edge shape is a free edge of the high linear method rich in amplitude symmetry.
The enclosure uses a CW backloading horn.
Also, the net comes in two colors, orange and brown, so I could choose the design according to my taste.
There was a speaker stand (BS-3) sold separately.
