Commentary
A floor-type speaker system equipped with a large passive radiator.
A 26 cm woofer and a 6.6 cm cone type tweeter receive the centrodesmus range of music playback. In addition, a ribbon type radiator is added to the ultra-high band and a 36 cm passive radiator is added to the ultra-low band.
A 26 cm cone type woofer is installed in the low range.
The diaphragm of this unit uses carbon graphite, which hardly changes in characteristics with time or changes in temperature and humidity. It is driven by a large 140 φ mm magnet.
In addition, a 6.6 cm cone type tweeter using carbon graphite is also mounted in the high range.
This tweeter realizes a wide bandwidth of 800 Hz to 20 kHz by taking advantage of the physical properties of cone, and high-quality reproduction is possible by using only 2 kHz to 10 kHz bandwidth.
For ultra-low frequencies, it is equipped with a 36 cm large diameter passive radiator made of carbon graphite.
In combination with an enclosure with an internal volume of 91L, it resonates only in the ultra-low frequency range of 30 Hz to 80 Hz and performs ultra-low frequency reproduction.
A ribbon-type super tweeter based on PT-R5 is mounted in the super high band.
In the ribbon type, the vibration system itself is the driving part, and the input signal can be faithfully converted by the vibrating air and the light diaphragm of equal mass, and the piston motion is made possible up to the ultra-high frequency band of 120 khz, which is beyond the audible band.
The enclosure is a floor type with a large internal volume of 91L and a slim style that does not require much floor space. In addition, the units on the baffle face are concentrated so that sound sources are gathered sharply.
It is finished by utilizing the grain of natural wood マスールローズ.
