DIY speakers Visaton BG 20 full-range speaker no tweeter dome + tweeter SC 10 N / making a crossover for acoustics Hello friends. in this video I will make a notch filter for a full-range speaker BG 20. I removed the tweeter dome from this speaker.  now you see the frequency response of the full-range speaker BG 20 with tweeter dome and without tweeter dome . I will select a notch filter empirically to remove this hump in the frequency response of the speaker. and I will also add a tweeter Visaton SC 10 N to the speaker. we will all see and try to hear the difference in sound.  housing for acoustics made according to the drawing of visaton solo100. let&see together how I selected the notch filter. First, let&look at the frequency response of the speaker without a filter. I have a filter for B 200 High-end full-range loudspeaker from SOLO 100, let&try to connect it and see how the frequency response changes.  new filter from the components that I have.  I will use a filter from Visaton solo 100 as the basis for the circuit.  diy 2 way speakers thank you very much
