The Crossover Design

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, 6 dB per octave.
• A capacitor at 105 µF 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 µF value, just connect two capacitors in parallel (e.g. 100 µF + 4.7 µF), as shown in the diagram above.
