The world’s first pure magnesium HR scorcher is used in the bandwidth critical for music reproduction.
By using a special molding method to create an HR diaphragm shape from pure magnesium, which has high responsiveness and little incidental sound inherent to metal, the generation of intrinsic resonance is suppressed and reproduction of a transparent and deep midrange is realized.

The φ100mm ferrite magnetic circuit, one of the largest in terms of aperture ratio, uses a pure iron pole piece with excellent magnetic characteristics to provide a light and natural expanse of sound field space.

*As of June 2008, according to our own research.

A pure magnesium diaphragm is used, which enables flexible and thick reproduction despite being made of metal.

In addition, a newly developed ridge dome with a different distance from the voice coil to the tip of the dome is employed to realize natural high-frequency characteristics without peaks in the highest frequency range by eliminating any inherent coloration in terms of materials and structure, and together with the Alnico magnetic circuit, enables lustrous high-frequency reproduction.

The woofer for mid/low bass/bass tones uses the HR diaphragm, which was developed as a light and strong diaphragm shape that suppresses inherent resonance.

The magnetic circuit for the mid/low bass woofer, which handles frequencies up to 350 Hz, uses a long voice coil system with two 145 mm dia. ferrite magnets.

The diaphragm is made of banana pulp, blended with several new materials including high modulus carbon using our proprietary paper-making technology to create a light and strong diaphragm with no habitual characteristics.

Aiming at reproduction of the lowest frequencies with a deep sinking sound, the woofer for bass has an ultra-long voice coil specification with a plate width of 14 mm and a voice coil winding width of 27 mm, and a large, powerful magnetic circuit that uses two φ156 mm ferrite magnets, the largest in its class.
The magnetic circuit with the largest driving force in its class reproduces powerful low frequencies with high responsiveness.

The enclosure is divided into an upper mid-bass woofer and a lower bass woofer, each with a capacity corresponding to the speaker unit optimized for the band it receives, and is a 4-way staggered bass reflex type.
The pedestal part is a floor standing type with three HR weights installed to prevent unwanted specific resonance by itself, and to adjust the resonance and balance the weight.

The baffle is made of a rigid 18mm thick beech plywood and a newly developed 15mm thick camphorwood and eucalyptus plywood.

The top, bottom, and side panels are made of 27mm-thick particleboard, which is made of 9mm-thick boards laminated and re-glued together to enhance rich resonance and rigidity. The back board is made of 18mm-thick MDF for optimal strength distribution and natural, clear sound.

The baffle is made of satin sycamore, which has a characteristic grain, and the sideboards are made of natural beech veneer with a glossy piano finish.

The G1300/G1302 is also equipped with a MID controller that flexibly responds to the listening environment, which has been well received by the G1300/G1302. This controller does not change the volume of the entire tweeter band like a conventional tweeter attenuator, but controls the connection between the screener and the tweeter.
Since the controller is not connected in series with the tweeter, the highest frequencies remain unchanged, providing excellent adjustability with no degradation of sound quality.

The input terminals are machined from copper and gold-plated in consideration of contact loss, and are compatible with bi-wiring. For internal wiring, newly developed copper/silver alloy stranded wires are used, and all contacts are caulked with gold-plated sleeves to prevent deterioration of sound quality.

The coils and capacitors used in the network are high-quality, low-loss coils and capacitors developed for loudspeaker craft use, and network elements appropriate for their class are employed.
