Flat-4 Effect Manufacturer Definition:
1st effect
Placement of opposed elements reduces mechanical vibration due to anti-resonance.
2nd effect
Twin element parallel drive improves sound pressure sensitivity of low to middle frequency sound.
3rd effect
External auditory meatus tuningTM technology using phase correction tubes dramatically improves middle frequency sound.
4th effect
Deletion of acoustic resistance and employment of small elements dynamically enhances ultra-high frequency sound and realizes wide sound propagation.
