This is a 50 mm Transducer, 25 u PET diaphragm, obtained the good effect of intermediate frequency, and has a lower distortion, which is suitable for OVER e-sports headphones, EAR and 30 Ω impedance.

This is a 14.2 mm Transducer, applied the diaphragm of a 9μ PEN, has good effect of high frequency sound, it is suitable for TWS headphones, 16 Ω impedance.

This is 40 mm sensor, suitable for TWS and ear headphones, impedance 32 Ω, adopts the DCCA copper clad aluminum wire circle, promote new and high frequency expansion in the clear.

This 12 inch 8 ohm Woofer driver features a strong ferrite magnet motor system with bump bottom plate and long throw
voice coil, which has high excursion. The distortion can be decreased by Aluminum short circuit ring at
low frequency, the semi-pressed paper cone uses a new mixed material of 40% pulp and 60% carbon
fiber to make the sound stronger and sonorous. Beyond that, the wonderful collocation of foamed rubber
surrounding, CCAW and short circuit ring can provide high SPL and extended high frequency. 
 

This 4 inch Aluminum Alloy woofer, Aluminum Die-Cast Frame with Mg-Li Alloy cone. It has good process
ability and high yield for mass production. Because of this special raw material structure and unique
processing technology, from magnesium lithium metal foil, the attributes of Magnesium Lithium offer
high strength, good rigidity, good heat resistance, low density and so on.
