Commentary
A multi-driver speaker system designed for listeners seeking high-quality sound.
Four 18 cm cone woofers are installed in the lower range.
It uses a large magnet with excellent breathability and a 40 mm diameter copper clad aluminum voice coil with a titanium bobbin.
A cast frame is used for the frame, making it a solid structure.
The mid-range features a custom-made 15 cm cone mid-range for high input resistance and smooth, fine resolution.
A 2.5 cm hard-domed tweeter is installed in the high range.
A newly designed titanium diaphragm is used for the diaphragm, and the influence of back pressure is suppressed by the structure that uses the magnet structure and rear cavity that ensure air permeability.
The network section is assembled on two independent epoxy boards.
We use carefully selected parts and wires such as large low-loss inductors and polypropylene capacitors, and set the slope high to reduce interference between units.
The enclosure is large enough to mount six units at the minimum required width, providing a sleek appearance with extended low-frequency reproduction, and a solid structure with careful internal reinforcement to minimize sound coloring.
The exterior is finished with a pair of mirror images with a decorative plate finish. Especially, the side panel is designed so that the pattern of the wood grain is symmetrical from left to right.
There were 5 kinds of finishes such as black ash, cherry, curly maple, rosewood and gloss black.
Comes with a floor stand that tightens the low range and improves stability when the floor is made of wood.
