Features
World's first* 13cm HR-shaped woofer with pure magnesium diaphragm
The world’s first 13cm-diameter pure magnesium HR diaphragm is used in the woofer.
Pure magnesium (purity: 99.9%), which realizes supple and thick reproduction and high responsiveness of metal, has excellent properties 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 squeal 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 120mm-diameter ferrite magnet, achieving smooth sound quality with high density and penetrating power.
*According to our own research conducted in August 2011
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 based on 19mm beech plywood, which has high strength and a straightforward resonance spectrum, valuing the resonance of the wood.
The G1300MG uses 19 mm beech plywood for the baffle, 18 mm CE plywood (camphor wood and eucalyptus) for the top, bottom, and side panels, and 15 mm high-grade MDF for the back panel to release unwanted vibrations and suppress turbidity generated by the cabinet itself.
The names “Violin Red” and “Fagot Brown” are generic color names.
The shade of paint will vary individually due to the hand-painting process of each cabinet.
The grain pattern of the wood is different because of the use of natural wood.
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 in the network elements.
Crimping process with sleeves is applied to the wire connections to thoroughly eliminate any factors that may interfere with sound quality.
Furthermore, the G1302MG/G1300MG use 19 OFC φ 0.32mm x 19 coaxial stranded wires for the internal wiring material, pursuing both power and delicacy.
In addition, 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.
