[@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.

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.

Sir what is the name core put inside the bobbin

I have mentioned in the video that I have used soft iron core.

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.

[@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.
