Product model: 148-32D
Diaphragm material: multi-layer nano biological material composite molding
Impedance: 32 ± 15% ohms
Frequency response: full frequency band (20-20000Hz)
Sensitivity: 116dB/mW

Maximum power: 5mW
Harmonic distortion: 3% (TMD%)
Driver size: 14.8 mm
Features:
The standard unit on the market is a 14.8 unit and a 14.1 copper ring sound film is used, while our factory’s 14.8 unit uses a 14.8mm copper ring sound film, with a larger film size, greater swelling force, and a larger sound field, which meets the permeability of a flat head and provides a deep sense of depth for low-frequency diving. In terms of flat head plugs, this one has a very high cost performance ratio.
Instructions for use:
Suggest customers to use a multimeter to test the conductivity of the unit after receiving it to ensure it is in good condition, and then weld it. The unit should be marked positive and negative
Pole, the colored one is the positive electrode, solder the positive electrode wire, the unmarked point, solder the negative electrode, and it is best not to exceed three seconds when soldering with a soldering iron, and the temperature should not exceed
If the temperature exceeds 385 degrees Fahrenheit and the soldering time is too long, it is easy to burn out the voice coil leads or directly damage the circuit board, causing unit short circuits and silence.
