Tak máme štandard na meranie domácich reprosústav:
citácia: | This standard describes how to determine the frequency response, directivity and maximum output capability of a residential loudspeaker. It is intended to determine the audio performance of a loudspeaker, not the loudspeaker’s ability to survive a given input signal. This standard applies only to loudspeaker systems, and not to raw transducers. |
