The Ocharaku Flat4-Kaede
The name Flat4 is derived from the description "Full-range 2-Element 4-Way Effect."
According to the company website this 4-way effect is as follows:
Placement of opposed elements reduces mechanical vibration due to anti-resonance.
Twin element parallel drive improves sound pressure sensitivity of low to middle frequency sound.
External auditory meatus tuning technology using phase correction tubes dramatically improves middle frequency sound.
Deletion of acoustic resistance and employment of small elements dynamically enhances ultra-high frequency sound and realizes wide sound propagation.
The Ocharaku Flat4-Kaede is priced at JPY 71,400
