During the OPPO PM-1's manufacturing process, drivers are closely matched to ensure optimum stereo imaging and soundstage.
Unique Planar Magnetic Sound
Utilising a planar magnetic driver , PM-1 features a transparent, highly dynamic sound that exhibits well-balanced tonal qualities .The diaphragm is driven in a symmetric pull-push manner evenly and the magnetic system and conductor patterns have been optimised for maximum sensitivity and consistency.
FEM-Optimised Magnet System
Maximise sensitivity and consistency of the applied force over the driver area.
Double-sided Spiralling Coils
Allows twice as many conductors to be placed within the magnetic field, which leads to higher sensitivity, better damping, and even drive force.
Seven-Layer Diaphragm
Ensures that it is very stable under thermal stress and vibration
