  • FBSPS-001
  • The speaker's performance depends mainly on the following parameters: Loudspeaker unit, frequency response, signal-to-noise ratio, sensitivity, impedance and antimagnetic function. 1. The wider the sound pressure frequency range of the Wireless Speakers, the better the frequency characteristics. 2. Frequency divider: Generally speaking, the performance of three division speakers should be better than that of two division karaoke speakers. 3. Sensitivity: Generally speaking, a speaker with a sensitivity of 90dB is enough to meet the needs of home audio. 4. Rated impedance: the common rated impedance of speakers includes 4 Ω, 6 Ω, 8 Ω, 16 Ω, etc. At present, the speakers are mainly driven by transistors or integrated circuit power amplifiers, and such amplifiers generally do not use output transformers, so the impedance of connecting speakers is mostly in the range of 4-16 Ω. In use, the impedance of speakers should be selected according to the requirements of power amplifiers.
