First, pay attention to speaker output sound is uniform, due to multi-media music, sound source, mainly gaming and general music-based, so a larger proportion of them treble, bass small.
Second, we must note that the ability to locate the acoustic field. Speaker positioning capabilities will have a direct relationship to the user to play games, watching Hp nc6120 battery DVD movies-spot results.
Third, the speaker should be noted that the frequency domain dynamic amplification limit, that the speaker volume when the user to open large and exceeds a certain limit, the speaker is still another area in the whole tone of the sound source to maintain even a clear signal amplification capability.
Fourth, we must pay special attention to whether there is resonant speaker cabinet. General box or plastic shell thin speaker in the low frequencies below 200Hz high-volume output, resonance phenomena occur. Resonance box appears sound quality will seriously affect the output, so users in the selection of speakers should be advised to select wooden shell of the speaker.
Fifth, we should pay attention to whether the magnetic nature of the chassis. Because the display is very sensitive to the surrounding magnetic field, if the speaker's magnetic field a larger image on the screen will be affected, or even decline in life expectancy led to the display, so extra care when selecting.
Sixth, pay attention to the airtight speaker cabinet. Because of the better Mitac 8375 battery speakers in an enclosed, the output quality, the better. Leak detection method is very simple, users will be hands on speakers outside the inverted-phase hole, if the sense of a clear or smoke into the air out of the phenomenon, it shows a good performance in an enclosed speaker.
Maintenance
Speaker sound system as a whole an important component, valued at about half of the whole system so it must be properly treated.
��� placed in direct sun exposure to avoid the place, not close to the thermal radiation equipment, such as stoves, heating tubes, etc., should not be placed in moist places.
��� speakers connected to the amplifier, you should first cut off the power amplifier in order to avoid damage to speakers. ��� feeder connection with the amplifier should be conservative when you can not pull in by the fall, positive and negative polarity can not pick the wrong. Feeders must be adequate to connect the speaker thick, not too long, so as to avoid loss and to make damping worse. In order to deviate from the Ibm thinkpad r40 battery frequency response of the maximum disability 0.5dB (0.75mm2 wire maximum length of 9cm, 1.5mm2 wire maximum length of 14m, 2.0mm2 wire maximum length of 21m.
��� should pay attention to the suitability of the speaker impedance amplifier recommended values
��� shall not exceed the rated power to use. Otherwise, sound quality will deteriorate, or even damage the speaker.
��� shell should be soft, dry cotton cloth wipe, do not wax or painted furniture, benzene, alcohols.
��� speaker surface dust can only be removed with a soft brush, can not use vacuum cleaner gettering.
��� speaker should be placed on sturdy, solid floor, so as to avoid bass attenuation. Do not place the speakers too close to the wall.
��� Do not place the speakers too close to the turntable, so as to avoid acoustic feedback caused by whistle.
