Commentary
A bookshelf type speaker system that uses a concave woofer.
A 20 cm cone woofer with a concave diaphragm is mounted in the low range.
The diaphragm is of the concave type with a concave center cap. By using the center cap itself as part of the diaphragm, the expansion near the crossover is minimized and the extreme resonance peak is reduced to obtain simple characteristics.
A unique radial edge is adopted for the edge, and by adopting an Ω shape with two types of curves with different radius of curvature, split vibration at the edge is suppressed.
A 3-cm dome type tweeter with an edge support structure is installed in the high range.
The enclosure uses a pressure balance system.
The pressure balance system is close to hermetic, and is designed to balance the internal pressure by allowing only unwanted vibrations outside the audible band to escape from the baffle port, thereby reducing the hermetic enclosure and the bus-ref-type boumey.
