TWEETER CROSSOVER CIRCUIT

  1. A single coil speaker is not good in handling high and low frequency at the same time.
  2. If we could filter out the low frequency and play it through a tweeter ,it will produce more sound quality than using a single speaker.
  3.  This is what is realized here.
  4.  Here the high frequencies are filtered out using a low pass filter made of C1,C2 and R1 and send to the tweeter.The low frequency is only fed to the woofer.
    NOTES:
    • The tweeter can be a 2 to 3 inch, 4 to 8 Ohm one .
    •  R1 is used to adjust match the the tweeters output level to that of woofer.
    • C1 and C2 are electrolytic capacitors.
    • R1 should be rated more than 2 Watts.
