Hey! Can anybody help me uit with schematics for 3-way cross over filters.

I am now starting with the PROJECT23 from And afterwards i wan to buy some speakers form a dutch e-bay site called

The schematics should also be noted the voltage and 'thickness' form the analog components, so i can buy them at the desk of my local electronics store.

I can not calculate it myself. Further pictures will follow from the back of the conusses as soon as i bought them.

Anybody URL ???

If you know the cross over components, you know the cross over points match with speakers. You know sensitivity of speakers match.
Then its only a matter of putting it all together.

If you do not have speaker of components then I recomend that you go to a two way system with a single high pass filter for tweeter.
You match woofer cut of with tweeter, tweeter can be woofer sensitivity up to -6db. best to be arround -3 db(fits in with the average curve of speaker). Really depends on speaker response and look at graphs if you can.
If ur woofer cut at 8k and you tweets can go below 8k. you can cross them over arround 8k. slightly earlyer slightly later depending on response of speaker.
You can also calculate cutt of freq ... lator.aspx
