Sound cone selection is a key link. The material and characteristics of the cone directly affect the sound. We finally adopted a woven carbon fiber cone as the cone of this speaker. The carbon fiber material is lighter and harder, and the sound performance is similar to that of the ceramic cone, but after the combination of weaving, the plane can be bent, the toughness is very good, and it can return to its original shape after moderate bending. Therefore, this woofer has the sound quality and advantages of a paper cone and a metal cone at the same time.
In order to increase the power of the horn, we choose 80 magnetic steel design, carrying 25 core magnetic circuit, and in the T iron and pot frame to do ventilation and heat dissipation design, so that the horn can not only adapt to high power work, but also long-term work is not affected. The speaker's power rating can actually reach 40 watts, which is about the same as a regular rambler 2.1 speaker. It can be imagined that this is a real power woofer.
According to our test, there is no abnormality or poor performance when the power of 4oW is input for 24 hours, and the power of the speaker is still relatively large. We recommend that the power of the speaker can be 20-40W.
The general recommendation is 3886 or 3116 digital chip power amplifier. The woofer is more powerful and dependent on the box body, which requires professional knowledge and skills. Car with words, in addition to pay attention to power, but also need to pay attention to the height of the horn, can not top to the window glass.
