A single coil speaker is not good in handling high and low frequency at the same time. 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.This is what is realized here.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.
Circuit Diagram with Parts List
- 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.
