This Instructable show how to make your own audio crossover.
My circuit garranties excellent high class audio quality.
Just a new design to reduce crossover frequency losses.
In this instructable you'll need the folowing items:
A soldering iron
Ferric Chloride or any other Cooper echent
A horizontal drive transformer ( found in televisions)
10uf and a 2.2uf non-polarized capacitor
1.5 mm to 3.5 mm drill bits
A speaker box with an tweeter and loudspeaker
A digitial or analog multimeter
A permanent maker
Six strips of wire preferable three different colours about 1.5 metres
Step 1: Summary Of Operation
It can be placed on a breadboard with ease, overall it shows you how to connect it.
Well the transformer that i used can be found in a crt television set and it must be selected based on the power rating of your speaker.
I have a 15W Loudspeaker and a 5W tweeter this transformer is fairly small, so if you plan to have speakers that are very powerful i advise you to get a transformer of similar ratio but bigger. The transformer's ratio is 1 : 5.
Its primary resistance was 0.8 ohms and secondary 3.4 ohms
The same goes for the capacitors the voltage range is small like 16v -50v for small power applications. As you increase your output power the voltage of the capacitors must increase to the range of 100v -250V. The value of the capactors usually stay the same. Use non polarized capacitors because they wouldnt be damaged by the alternating voltage.
