G1302

The enclosure is a staggered bass reflex type, divided into an upper 2-way section and a lower bass section, each with a capacity optimized for the respective bandwidth. Different woofers, each designed exclusively for this purpose, are used to achieve a sense of volume and speed.

Three HP weights, which do not cause unwanted specific resonance by themselves, are attached to the pedestal portion to adjust the resonance and balance the weight of this slim tall-boy type.

Like the G1300, the G1302 uses a pure magnesium diaphragm that delivers the supple, thick reproduction of a soft dome and the high responsiveness of metal, while the finely tuned tweeter for the G1302 delivers a softer, smoother high-frequency expression with natural mid-highs.
The crossover frequency is set at 1.6kHz to achieve a sense of substance and pinpoint sound image localization of flesh tones.

In addition, a newly developed ridge dome with a different distance from the voice coil to the dome tip is used to eliminate the inherent noise caused by the dome, and a thorough elimination of inherent coloration is sought from the material and structural aspects.

The low-frequency woofer is designed with a long voice coil to reproduce low frequencies with breadth and volume, and a 120mm ferrite magnet is used for the main magnet as in the mid-range and low-frequency woofers.

In addition, a 120 mm dia. ferrite magnet of the same size is used for the boost magnet to strengthen the magnetic flux, resulting in a double magnet configuration. The magnetic circuit has the largest driving force in its class and reproduces deep low frequencies with high responsiveness.

In addition, a low frequency crossover at 160Hz was considered in the coil used, and a low-loss coil using Hiµ material as the core material was newly developed for the G1302.

The woofer adopts the HR shape, which was developed by introducing new paper-making technology into the HP diaphragm, which was developed as a light and strong diaphragm shape that suppresses inherent resonance.

In the magnetic circuit, a large 120mm diameter ferrite magnet is used for both the main magnet and the boost magnet, and a short voice coil system is used to obtain a strong magnetic flux, which enables low distortion and excellent response.

The diaphragm is made of banana pulp, which has strong fiber-to-fiber bonding strength, and is blended with several new materials, including highly elastic carbon, using our proprietary paper-making technology to create a light and strong diaphragm with no habitual characteristics.

The 13cm diaphragm is designed to reproduce high speed bass sound with high response and a core, taking advantage of its small diameter by approaching the sound from various angles.

The G1302 is also equipped with the G1300’s popular MID controller, which flexibly responds to the listening environment. This controller does not change the sensitivity of the entire tweeter band like a conventional tweeter attenuator, but controls the sense of connection between the woofer and the tweeter.
Since the controller is not connected in series with the tweeter, the highest frequencies remain unchanged, providing superior adjustability without the sound quality degradation that is a concern.

The input terminals use gold-plated terminals machined from copper in consideration of loss to the contact points, and are compatible with bi-wiring. We also pay close attention to the sound quality changes caused by short bars when bi-wiring connection is not used, and the copper/silver alloy wires used in the internal wiring are used for short bars to prevent deterioration of sound quality.
The coils and capacitors used in the network are luxurious network elements beyond their class, using high-quality, low-loss OFC copper foil coils and capacitors developed for loudspeaker craft use.

For the enclosure material, a rigid 18mm-thick beech plywood is used for the baffle plate to emphasize the sound of natural wood, and 18mm-thick particleboard is used for the top, bottom, and side panels, which are made of 9mm-thick boards laminated and re-glued to increase rich sound and rigidity. The back panel is made of 15mm-thick MDF to optimize strength distribution and provide a natural and clear sound.

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