Commentary
A 3-way bookshelf type speaker system that inherits the flow of HS-3.
A 25 cm cone type woofer is installed in the low range.
Lordi original technology ギャザードエッジ is placed on the edge, and low frequency reproduction is improved by combination with magnetic circuit using 110 φ -60 φ -15t magnet.
In addition, it is equipped with a rodio actuator (low distortion magnetic circuit).
A 5 cm cone type tweeter is installed in the high range.
A magnet of 80 φ -40 φ -15t is for the magnetic circuit, and a new material, polyimide heat-resistant fiber is used for the voice coil bobbin, and thermosetting self-fusion wire is used in combination to improve the input resistance.
For the edge, roll edge which is a part different from the diaphragm is adopted, and it is combined with high quality micron glass wool inserted in the magnetic circuit to enable low fo.
The center cap uses a titanium diaphragm to improve the high frequency range.
A 1.4 cm dome type super tweeter is installed in the super high band.
Titanium is used for the diaphragm, and directivity is improved by making the diameter small.
In addition, a magnet of 45 φ -22 φ -8t is used.
The enclosure is a bass-reflex type that employs a frameless baffle structure with no edge on the front baffle plate, and two types of sound absorbing materials (glass wool and natural fiber) are used inside to improve sound quality.
The exterior has a Mersey-rose-like finish.
