Horn with good density magnets, the dB level is relatively high, up to 93dB, small power amplifier will be able to launch large volume than the same size of the horn; a large voice coil, water basin, basin water hardness course than ordinary hardness to hard flat basin, this basin is less vibration offset bit; the shape of the screw thread the side edges, thread from the United States, the edge of the thread benefit is very small when the amplitude of the vibration of the loudspeaker sound. With 6 screws fixed, this does not need to be said, of course, to be more stable. Because of low volume on the vibration of the loudspeaker basin, encouraging air flow in the issue, the speaker behind the 6 large holes, ordinary horn opened 5 of the air horn basin encouraged more let.

A lot of people think that loudspeaker box is designed for OK, but it is not good if it doesn't meet the requirements. A German designer once said in the audio book, "designing a loudspeaker box is only preliminary, and more importantly, debugging." And the power amplifier with power amplifier is also very important, sometimes is not enough, a slightly larger volume of the horn will sound, some people do not understand the strange horn, is actually not enough force in the horn out of power, after all, the amplifier would not speak, would not say that he is not. Some problems often encountered in debugging: if the bass more mixed, mixed, noise, or the volume too much, these can be placed in the box with sound-absorbing cotton, can improve a lot, if little bass, treble more, it is necessary to pay attention to a phase, phase bass is the superposition of RP is low tone offset each other; the correct phase of treble attenuation, a series resistor and a resistor, the resistance value of the amount of attenuation can be decided, slightly changed the frequency divider. With the debugging and power amplifier, high power amplifier audio speakers sometimes, high tone, will feel the entire range of treble, bass less, you can change the power amplifier pre op amp feedback capacitors, increasing the capacity of the whole range of variable to reduce the bass, let the variable bias high tone. Try to cooperate and try different music.
