Passive Cross over network for Sub woofer

This video is for making a simple Crossover filter network for use with a Sub woofer, which cuts down higher audio frequencies above 200 Hz. This network will pass low frequency range of 20 to 200 cycles which is most suitable band for a sub woofer. This network can handle sufficient power upto 300 watts. For higher power, the coil wire has to be thicker . A non polar 100 mfd capacitor can be made by joining negative ends of two 200 mfd 100 volt capacitors which becomes 100 mfd 200 volt.
If the coil is made with a coil winding machine you can check the no. of turns. Otherwise you have to calculate the weight of the wire from wire gauge chart. I shall share about other types of network for two way and three way speaker systems in my next episodes of Making Loudspeaker series.

[@shiernanpapin85]

Nice idea Sir. Yes, the bass is more gain. But that's much better to call; 'high frequency killer', than a :subwoofer booster'. Because the amount of power from amplifier to distribute in speaker is decreased by cancelled high frequency. Anyway thanks for video.

[@sux2bu883]

Thank You for taking the time to show us (your students) how to wire this configuration. How do we find what inductor and capacitor to use for different speakers configurations ? Like smaller, bigger speakers more powerful and less powerful amplifiers .

[@makingloudspeaker]

To calculate values of inductor and capacitors you have to use some mathematical equations. If you want to know about it please contact me at whatsapp no.

Sir but every time complition of one layer of winding the diameter gets increased for second layer ,then third layer and soo on.... how to calculate indctance of inductor inductance because the diameter increases ,even if bobbin is short number of layers increases, if it is long noof layers decreases then also diameter changes but we are calculating for bobbin diameter, i get confused how sir can u explain

[@makingloudspeaker]

From standard wire gauge chart you can find turns per inch/cm, then get no.of layers, mean dia, mean length x no. of turns, total length of wire and weight of wire for required number of turns. You can get tips from any transformer winding handbook. Thanks.

For 4 ohms inductor value will be half and capacitor value should be double.

@@makingloudspeaker thank you 😊 so much

[@kathiravankalidass7852]

and more over that 6.5 mh inductance may filter around 500hertz only , some technical person tell if it is around 63 mh it may give around 40 hz like he tell , now what is your idea sir

[@makingloudspeaker]

Thanks for your comments.There is a standard equation to find out the values of C and L for any crossover frequency and impedance.
That is C=1/2πfR and L=R/2πf
You can find out values of inductors and capacitor as required.

For full range speaker cross over network is not required. If you want to add tweeter, you will have to use a high pass filter.

What is the permeability of iron core that you used in the video?
Can you suggest online calculator (or formula) for inductance with multilayer iron core [like steel core with permeability of 2000]

[@makingloudspeaker]

The inductor coil shown in the video is made on trial basis.
However,
The absolute permeability of a soft iron core is given as 80 milli-henries/m (80.10-3). ... While, air may have a permeability of just one, some ferrite and permalloy materials can have a permeability of 10,000 or more.
