RECOMMENDATIONS FOR THE USE OF SPEAKERS

The service life of speakers depends largely on the correct choice of amplifier, settings and acoustic design. It is necessary to select an amplifier with a rated power not exceeding the rated acoustics power.
Correct matching of a car head unit (the source unit) with the amplifier will allow you to get a clean, undistorted signal supplied to the speakers, which will prevent overheating and failure of the voice coil.
Like a new car that has just rolled off the assembly line, the speakers of which only what was taken out of the box, it is necessary to warm-up first.
Parts of the speaker moving system cannot immediatelly work at their best of a necessary level, just like an athlete cannot show a decent result without a preliminary warm-up.
A certain period of time must pass before the voice coil centering washer and cone with suspension are flexible enough and elasticity for adequate performance. A new speaker takes 70-100 hours warming up at 30% power.
Of course, the figures are approximate.
If during operation of the acoustics at high volume You feel a strange smell, you need to reduce volume and let the speaker cool down at a low volume.
Recommended settings for a a car head unit volume level is no more than 80%.
HPF should be set to 70-80Hz, bass boost – 0. Amplifier sensitivity should be set to 50%.
