Simple Tweeter Crossover Circuit

Circuit Description

The circuit diagram of tweeter crossover circuit has been described here. The advantage of this circuit over circuits of single coil speaker is that it can handle both high and low frequency signals simultaneously. A tweeter circuit can produce a better sound clarity than single speaker circuit if low frequency is filtered out from the amplifier output.  That principle is applied in this particular circuit. Here a low pass filter circuit consisting of elements C1, C2 (25 uF) and potentiometer R1 (100 ohm) is used for filtering high frequencies. This filtered output is given to the tweeter (K2). The existing woofer (K1) is driven with the low frequency.

Notes

  • The power rating of potentiometer should not be less than 2 Watts.
  • Use electrolytic capacitors for C1 and C2.
  • The tweeter can be a 2 to 3 inch, 4 to 8 Ohm one.
  • Potentiometer R1 is used to adjust the output level of tweeter to that of woofer to match both.
