The whole construction process of "Pit Vipers"

I started construction again today

This is my frequency divider PCB

[9sheng]

I haven't found a capacitor of the appropriate specification for the mid-range C2, so I chose two capacitors in parallel. Of course, one capacitor of the appropriate specification can be directly welded in the PCB. I only reserved 2 capacitor welding positions.
It is very interesting that I designed the mezzo PCB into the shape of "USS Enterprise (NCC-1701-J)"!





For the C5 capacitor of the bass part, I also used two capacitors as parallel connection, and he also reserved the position for welding a single capacitor.

Three parts of Crossover




Find a suitable position in the box,

Start fixing the base of the frequency divider

The installation position of the frequency divider is behind the woofer. There is enough space. It is very convenient for later disassembly, upgrading and maintenance.



The speaker terminal will also be installed next to the bass divider.


Starting from the frequency divider, I need about 40cm bass speaker line, 50cm mid-range speaker line and 60cm tweeter line​

Some great ideas on crossover board layout. Very satisfying to watch.
