Speaker types:
1. Electric speaker
Electrodynamic loudspeakers have the characteristics of soft sound and high power. It is important to measure the maximum linear sound pressure level SPLmax of 7 electrodynamic loudspeakers in a large-signal working state, so as to calculate the corresponding maximum linear displacement Xmax.
2. Intermediate frequency speakers
As long as the frequency response curve of the mid-frequency loudspeaker is flat, the effective frequency response range is larger than the width of the sound reproduction frequency band it bears in the system, and the impedance is consistent with the sensitivity and the low frequency unit. Sometimes the power capacity of the midrange is not enough, you can also choose a higher sensitivity, and the impedance is higher than the midrange of the bass unit, thereby reducing the actual input power of the midrange unit.
