Features
13cm HR-shaped woofer with pure magnesium diaphragm
The woofer uses a 13cm-diameter pure magnesium HR diaphragm.
Pure magnesium (purity: 99.9%), which realizes supple and thick reproduction and high responsiveness of metal, has excellent characteristics such as low specific gravity, high sound velocity, and high internal loss, but is extremely difficult to mold.
This has resulted in an ideal diaphragm that has the high density and penetrating power of a metal diaphragm, while at the same time suppressing the peculiar ringing characteristic of metal.
Furthermore, the edge supporting the diaphragm has a UDRT shape that allows the front and rear amplitudes to be close to symmetrical, contributing to accurate and clear reproduction of the sound field.
This is driven by a powerful magnetic circuit using a large 120 mm diameter ferrite magnet, achieving smooth sound quality with high density and penetrating power.
Ridge-dome pure magnesium tweeter
The tweeter also uses the same pure magnesium diaphragm (99.9% purity) as the woofer, and is equipped with a powerful magnetic circuit using a total of three 40mm-diameter neodymium magnets (two stacked + one boost magnet).
A 20mm-diameter diaphragm with a ridge-dome shape is used to realistically render the sound image along with the excellent directivity characteristics of a small aperture.
The substance of the flesh tone and pinpoint sound image localization will make you feel close to the artist appearing in front of you.
By keeping the propagation speed of the woofer and tweeter diaphragms at the same level, a natural and smooth tonal connection is achieved, as if the speaker units were one.
Beech plywood base cabinet
In order to reproduce the beautiful resonance of the instrument, the cabinet is made of beech plywood for the baffle, which has optimum rigidity, and CE plywood (camphor/eucalyptus) for the top, bottom, and side panels, while the back panel is made of high-grade MDF to release unwanted vibrations and reduce the turbidity generated by the cabinet itself. The back panel is made of high-grade MDF to release unwanted vibrations and reduce turbidity generated by the cabinet itself.
bi-wiring input
The input terminals are machined from copper and gold-plated instead of brass, which is commonly used, to avoid contact loss.
In addition, we pay close attention to the sound quality changes caused by short cables when bi-wiring connections are not used, and use OFC φ0.32mm x 19 coaxial stranded wires, which are also used for internal wiring, to minimize changes in sound quality.
high-definition network
Luxurious design using high quality sound elements beyond its class for the network elements. Crimping process with sleeves is applied to the wire connections to thoroughly eliminate any factors that may impede sound quality.
For the internal wiring material, OFC φ0.32mm x 19 stranded coaxial wires are used to achieve a powerful and delicate sound.
The tweeter network circuit incorporates a MID controller to accommodate a wide range of music genres.
Since this controller is not connected in series with the tweeter, it can adjust the mid and high frequency range from 1.6kHz to 10kHz, which is important for music reproduction, without attenuating the entire bandwidth, in the range of +1 to -2dB without degradation of sound quality.
