The maintenance of the speaker unit (whether in the box or the newly purchased speaker unit).
(1) Carefully remove the speaker unit in the finished box, be sure to be careful, and mark the position of the box and the speaker with an oily pen, so as to reset and install after good maintenance.
(2) prepare a box of imported car wax (imported brand cars with) evenly spread on the magnetic steel on the upper and lower two layers of T iron, generally the T iron are iron galvanized products, if the basin frame is iron frame must also be treated like this, let the wax attached to it, do not erase it, can prevent N years from rust.
(3) the speaker unit from the sound volume to the wiring end of the two parabola of woven soft copper wire, also must be coated with wax, and finger back and forth evenly, do not erase it, in order to prevent a long time, the lead black become elastic and reduce the impact of work.
(4) If there are mildew spots and white spots in the paper base or paper base composite basin, please use medical liquor Jing cotton ball to wipe them carefully and quickly from the back (liquor Jing cotton ball should be twisted half dry and half wet, not too wet, and it should not permeate to the surface of the sound basin). If there are mildew spots on the surface, you can only use 40-45 degrees of warm water, add a few hand sanitizer shampoo, use a clean soft towel dipped in water, wring and wiping, master moderate, do not repeatedly wipe. Do not use wine, such as Jing, with volatile organic solution to wipe it.
(5) Frequency divider maintenance. First take a look at the frequency divider, there is just a series connected in the frequency divider and to the GAO speaker that capacitor, is not the GAO quality of MKP frequency divider capacitor (general capacity and voltage is 2.2-6.8uF / 100-400V, depending on the different frequency points and capacity is different), such as the use of the then do not move, Otherwise, in any case, a GAO quality MKP frequency divider capacitor should be replaced.
(6) GAO loudspeaker in the pot (generally 1-3 months), and then for a period of time, about half a year to a year or so, and then the bass unit on the speaker removed (GAO sound don't move) rotation of 180 degrees orientation and then installed back (the first maintenance has been marked, this time as long as the installation of the upside down position), In order to make the speaker more balanced under the influence of their own gravity, at the same time to see if there is any need to fill wax, such as the need to fill up.
