Subwoofer filter using one transistor

Subwoofer filter using one transistor is very very simple for filtering your subwoofer tone control. This circuit diagram for subwoofer filer using one of transistor :
Subwoofer filter using one transistor circuit diagram
Subwoofer filter is using for filtering audio tone signal, subwoofer tone about 40Hz - 100Hz. Input audio is stereo , and output to mono subwoofer output. It' very simple subwoofer filter, you just need a few component resistor and capasitor, and basically strenghening by 1 transistor , the transistor just using C945 ot C828

Component list Subwoofer filter using one transistor :
  • Q1   C945 / C828
  • C1   1 Uf
  • C2   100nf /ceramix104
  • C3   1uf
  • C4   1uf
  • C5   1uf
  • C6   1uf
  • C7   100uf
  • R1   10k
  • R2   47ohm
  • R3   220k/470k
  • R4   10k
  • R5   10k
  • R6   10k
  • R7   1k
  • R8   2k2
