Commentary
Coaxial 2-way speaker unit.
In order to improve the low-frequency characteristics, the newly developed UL edge is used for the edge part, which makes compliance large and stable and lowers fo.
The magnetic circuit uses a magnet with a weight of 650g and a yoke with high permeability to improve efficiency and damping.
A horn type tweeter is installed in the high-frequency part.
