Commentary
The Control Series speaker system combines innovative design with excellent digital reproduction capability.
A 13 cm cone type woofer is installed in the low range.
A cone laminated with a high polymer black film on a pulp base is used for the diaphragm. A wide roll edge made of natural edge rubber and a high polymer suspension damper made of polyimide resin are used for the diaphragm to realize a powerful deep low sound despite being small in diameter.
Mid-range with 5 cm dome mid-range.
It uses a diaphragm that combines a pure titanium diaphragm with a free edge structure to achieve high-speed and high-grade mid-range sound. The voice coil uses super-heat-resistant polyimide resin developed from space optics to reduce eddy currents in mid-range sound and achieve clearer sound quality.
A 2.5 cm balanced drive tweeter is installed in the high range.
Pure titanium diaphragm is used for the diaphragm. By using the same material for the mid-range and diaphragm, the connection of sound from the middle range to the high range is made smoother.
Uses an anti-magnetic design.
The enclosure uses a bass reflex system.
Special mounting bracket is included.
