1. Is the damper correction network a frequency divider? Many believe that adding a fullrange speaker unit constitutes a frequency divider. However, rigorous manufacturers incorporate the network solely to adjust parameters in a favorable direction to achieve the desired outcome. 2. The specific auditory effect is the attenuation of peaks in the mid and frequencies, resulting in a more balanced overall sound. Notably, the notch filter is employed for finetuning the sound, and the assembly makes a difference. For programs with average sound quality and lowend amplifiers, this effect may not be as noticeable. 3. Is a trap filter ? No, it is not. It suppresses the frequencies, and those who prefer brighter highs may not need a notch filter. Additionally, those without demands may not require one. In fact, traditional lowend fullrange speakers were not designed with this in mind due to cost and technical constraints. However, our actual testing shows that a quality speaker with a notch filter can elevate the sound performance to a higher level. 4. Why use an LCR correction network (notch filter)? The flatness of the frequency response curve is one of the most crucial and direct factors affecting sound accuracy. The function of the LCR notch filter is to balance localized peaks in the mid or uppermid frequency range of the speaker's frequency response curve, maintaining reasonable flatness and enhancing the sound to a level.
