Commentary
38 cm cone shaped woofer unit.
The high-frequency characteristics are improved by adopting curved cone for the shape of the cone paper.
Excellent transient characteristics are realized by adopting a 5.9 kg magnetic circuit using an Alnico V magnet, a 10.2 cm diameter voice coil, and lightweight cone paper.
130A has 8 Ω specifications, and 130B has 16 Ω specifications.
