In professional recording scenarios, the frequency response of the speaker has extremely strict requirements. Specifically: The frequency response requirements of a professional recording studio to the speaker must be straight and wide. 

Only when the frequency response is straight can the audio not exaggerate or weaken the sound in any frequency band and accurately restore the original state of the sound; while the wide frequency response range allows the audio to fully capture and reproduce every sound detail from extremely low frequencies to extremely high frequencies, whether it is a low and thick bass or a crisp and bright treble, it can be presented truthfully. 

This will ensure that the recording and monitoring sound is true and reliable, provide accurate sound reference for professional recording work, help recorders and musicians make accurate judgments, and ensure the high quality of the recording works.
