Beyma CD10Nd 8 Ohm 70W 1" Bolt On Compression Driver
Beyma's unique, patented PM4 diaphragms incorporate a new high tech polymer never used in audio before.
Delivering a stronger joint between the diaphragm dome and the voice coil former, resulting in high power handling and the ability to withstand extended duty cycles, PM4 diaphragms have been designed to bring a more transparent sound. After bringing excellent results to reference acoustic systems, PM4 technology is now available in a range of compression drivers of exceptionally natural tonal qualities and stability.
