CORAL BX-1005D
Price unknown (1 unit, around mid 1970 s?)
Commentary
3-way bookshelf speaker system.
A 25 cm cone type woofer is installed in the low range.
Natural pulp-blended curved cone with moderate internal loss is used for the diaphragm, and combined with skybar edge with excellent linearity for large amplitude, low frequency with less distortion is realized.
The mid-range is equipped with a 10 cm cone type squaker.
This unit is fully enclosed to prevent the adverse effects of the sound pressure of the woofer.
A 3 cm hard dome type tweeter is installed in the high range.
The diaphragm is made of a newly developed laminate film, so that it is light and hard and has an appropriate internal loss. Combined with the CCAW lightweight voice coil, the piston band has been greatly improved.
In addition, high efficiency, low distortion rate and wide directivity are realized by a diffuser and a strong magnetic circuit designed based on detailed calculation.
The enclosure uses a bass reflex system.
