This speaker system is the top model of the High Resolution Series.
A 38 cm cone type woofer is installed in the low range.
This unit is driven by a Sampha ear power amplifier built into the speaker system and acts as a servo-controlled subwoofer.
The mid-range has 2 13 cm cone mid-range units.
This unit is named MAG alloy mid-range and uses a concave diaphragm made of magnesium / aluminum alloy.
A 2.5 cm hard-domed tweeter is installed in the high range.
Diamond-coated titanium dome is used for the diaphragm.
Anti-magnetic design is applied.
An acoustic suspension system is adopted for the enclosure, and a tall boy type is realized by mounting a woofer unit on the side.
