Commentary
This is a 3-way speaker system that adds a super tweeter to the 2-way system that uses a woofer originated from LE14 and the traditional 175 series compression driver.
A 35 cm (14 inch) cone type woofer of LE14 series using natural pulp diaphragm is mounted in the low range.
The frame of this unit is a square frame made of die-cast aluminum, which firmly supports the magnetic circuit and prevents twisting and deflection at large amplitude.
A horn type tweeter is used for the high range, and a 2-inch compression driver 175Nd-1 using neodymium magnet is installed as the driver.
A flat front biradial horn made of MDF is used for the horn part.
A 2.5 cm (1 inch) ring type super tweeter, UT-405, which has a regenerative capacity of more than 70 kHz, is mounted for the super high frequency band.
The diaphragm uses a 2.5 cm diameter Tempered titanium diaphragm with a slit-type horn gap.
The enclosure is made of MDF and uses Rosewood-style natural wood with round side panels with high gloss finish.
In addition, there were 2 types of top plate, marble top which mounts natural marbles and glass top which combines natural wood and glass.
Sold separately, there is a round design wood stand with a unified design.
