The crossover will cut at 500 hz, this will help the distribution of the sound in the woofer.
A coil with 0.95 mH cuts off the bass over 500 hz, 6dB per octave.
A capacitor at 105 microF cuts off the highs on the low side 6 dB per octave.
This is a part of the project where it’s open for experiments checking out more exotic and expensive solutions and types of crossovers to see if they make any difference. I was not able to find anything other than the normal grade stuff (i.e. crummy), but it is a prototype, so that’s fine! To obtain a 105 microF, just connect two capacitors in parallel, as shown in the diagram above.
