Commentary

A 4-way large-floor speaker system that employs a horn unit.

A 38 cm cone type unit is used for the low range.
This unit is driven by a 11000 gauss magnetic circuit with a high magnetic flux density of 180 φ x95 φ x20mm ferrite magnet and and a ferrite magnet of φ x95 φ x20mm.
In addition, the support system is equipped with an edge with moderate internal loss and excellent linearity of displacement, a polyimide laminate length damper with excellent linearity and reliability, and a reinforcing ring, etc. to constitute a highly effective suspension system.

A horn type unit is used for each of the middle and high areas.
Ultra-hard duralumin diaphragm is used for the Scoker, and titanium diaphragm is used for the Tweeter.
The tweeter uses free edges, multiple equalizers, etc. to improve the elongation and transparency of the high frequency range.
The horn section uses a secaural horn (horizontal diffusion angle 90 °) for the squaker and a catenoidal horn with an acoustic lens (horizontal diffusion angle 120 °) for the tweeter.

A horn super tweeter is used for the super high frequency range.
