Description Features: brand new and high quality The bass frequency point is not necessarily accurate, and it is only for reference:1. The woofer used when the bass is in position A will emit bass, but will not emit subwoofer (bass) below 100Hz. 2. When the bass is in position B, the voice of the bass speaker is limited to more than 300KHz (the bass gives consideration to the bass). 3. When the bass is in C position, the bass speaker limits the bass, and the frequency is above 400Hz. The high pitch point may not be accurate, but it is only for reference:1. When position A is 3.4uF, the tweeter is limited to above 2KHz. At this time, the tweeter gives consideration to the middle tone, which belongs to the middle high tone (loud). 2. When bit B is 1.2uF, the treble pronunciation is limited to more than 7kHz, belonging to the frequency band close to the super treble (the third ring). 3. When the C bit is 2.4uF, the treble pronunciation is limited to more than 3kHz, belonging to the treble (second ring).
