Commentary
A 3D speaker system with egg-shaped face cabinet satellite speakers and subwoofer.
The satellite speaker uses an elliptical enclosure that is long in the vertical direction and a net grill that controls diffraction waves to form a large wave front, and reproduces sound with a sense of depth even when playing at close range.
In addition, a 5 cm cone type unit is adopted for the unit.
A high-efficiency D-class amplifier is used in the amplifier section of the subwoofer. Because of its high conversion efficiency, this D-class amplifier can be made smaller than AB or B class amplifiers.
The unit uses a 10 cm cone type woofer and a 12.5 cm passive radiator.
The passive radiator unit is a double-edged symmetrical unit with good linearity and large amplitude. By using this passive radiator instead of a bass-ref-type duct, it realizes low distortion, wide bandwidth and rich low-frequency reproduction while reducing the size.
