The correct connection of speakers and tweeters in a speaker to obtain better sound quality, without danger of burning the amplifier components is something that not everyone respects. We then give two simple circuits in which the speaker and the tweeter are shown in the right way to connect. In these circuits, C1 is a 47uF x 50 V bipolar type, which capacitor can be obtained by connecting two 100 uF x 25 V capacitors in opposition. The L1 coil consists of 100 turns of 22 AWG wire in a shape of approximately 1cm in diameter without core. The author used an empty thread spool for this purpose.
