Commentary
A compact speaker system that can be mounted on the wall, pursuing high efficiency and sound reproduction.
A 20 cm cone type woofer is installed in the low range.
The edge uses a rubber-like urethane edge to achieve high compliance and low symmetry. In addition, by using a strong frame, resonance of the frame itself, which occurs during heavy bass reproduction, is suppressed as much as possible.
A 5 cm cone type tweeter is installed in the high range.
This unit is equipped with a sub-frame with an orifice structure in the chamber. By eliminating standing waves in the chamber, it prevents unwanted sound from sticking and realizes high-sound reproduction with excellent transient characteristics.
In addition, the center cap is made of titanium alloy with high rigidity and excellent specific elasticity, and by suppressing split vibration, a smooth high sound range is obtained.
A 90 dB output sound pressure level is achieved by adopting a powerful magnetic circuit and a bass reflex system.
In addition, the voice coil has excellent heat resistance to provide sufficient input resistance.
A 15 mm thick plate is used for the enclosure, and a strong structure is achieved through repeated modal analysis and hearing tests.
Wall mount brackets on the rear of the enclosure allow for wall mount to suit room conditions and preferences.
