A good Speaker design uses a combination of drivers and crossovers to let each driver focus on those frequencies it can produce accurately. This neodymium midrange speaker is designed to control the "middle" part of the spectrum, between 500 Hz and 4 kHz. This mid-car speaker is probably the most important frequency range, as the most audible sounds, such as musical instruments and human voices, are produced in this range. The frequency range of these slim midrange speakers has 74 ~ 3KHz. All speaker produces certain frequencies that are softer or higher than others. If you assume that your ultimate goal is to create a more accurate sound or music, so the less variation in loudness between frequencies in other words that the flatter the frequency curve, and that makes the better quality of the speaker.
