Commentary

A peaker system developed based on the policy of studio monitor.

Equipped with 20 cm cone type woofer 116A in the low range.
The cone paper is made of materials with the most suitable mass and compliance. The low-frequency characteristics are relaxed and a low distortion rate is achieved. The voice coil driving the cone paper is made of 5 cm diameter copper ribbon wire edgewise wound. The larger diameter reduces distortion and takes into consideration the heat-resistant effect of the Dainyu force. The frame is made of an aluminum die-cast frame to reduce resonance.
An Alnico V magnet is used for the magnetic circuit, and the pole piece, top plate, gap, etc. are also precisely processed to create a high quality structure.

A 3.6 cm cone type direct radiator LE26 is mounted in the high range.
A 1.6 cm diameter voice coil is driven by a magnetic circuit with a high magnetic flux density of 15,000 Gauss to improve transient characteristics, and the diameters of the cone and center dome are designed as small as possible to improve directional characteristics.
In the LE26, the cone circumference is covered with a hard material with a gentle slope, and the unit and baffle plate are attached together to eliminate harmful reflections and effectively eliminate phase distortions.

The network section is designed using JBL's technology to correct the phase and flatten the impedance characteristics.
In addition, high-quality parts such as low-loss inductors, high-voltage capacitors, and resistors are used to reduce distortion.

A continuously variable level control on the rear of the enclosure provides high-range level control.

The enclosure uses a 19 mm thick, high-density particle board, and the interior is filled with sound absorbing material to absorb standing waves.
The exterior has a walnut finish.

A new type terminal with low contact resistance is used for the input terminal.
