**Preventive maintenance of a driver or high frequency cornet.**
Preventive maintenance of a driver or high frequency cornet.
The driver that I chose to maintain was the Eminence psd-3006, whose features are:
• 2-inch titanium diaphragm.
• It has a ceramic magnet.
• 100W AES power capacity.
• Nominal impedance 8 ohm.
• Frequency response (800hz-20000 kHz).
• Eminence manufactured in the USA.
** Tools to be used: ** Allen wrench, 10mm wrench, spline screwdriver.
Steps to follow:
** First step: ** The diffuser is separated from the driver by loosening the screws with the 10 millimeter wrench.

** Fourth step: ** With a sheet of machine proceeds to clean the driver inside the channel where the membrane is placed in order to remove accumulated dirt and dust, since a dirty driver carries bad sound, or can even damaged because it causes friction between the membrane and the wall of the magnet.

** Fifth step: ** Proceed to arm the driver again, if we see in the photo of the magnet has a hole which is the guide where the membrane goes, and is not misaligned with it.

** Eighth step: ** We proceed to test this driver to see how it works, the positive cable is placed with the red connector of the driver, then the negative cable with the black connector, a music is placed and there is a video Short of how the driver is sounding.
