2pcs 40mm Graphene Headphones Speaker Unit Composite Diaphragm DIY HIFI Headphones Drivers 32 Ohm
The dome of the diaphragm is made of biological sound film material, and the edge diaphragm is made of graphene material, which is durable. The middle diaphragm (to enhance resolution and increase low-frequency), and the back magnet is strong and magnetic. It is important to pay attention to it while welding.
Graphene composite biological diaphragm benefits high resolution! The tuning of the driver is balanced and slightly higher pitched. If you prefer bass effect, please remove the tuning paper on the back of the speaker unit.
Brand new disassembled headphones speaker unit, some speaker units may have some appearance flaws, but the quality is very good, please don’t worry.
NOTE: The unit has strong magnetism, don’t put two drivers together, which can easily cause the diaphragm to flatten.
