Subwoofer circuit:
This is a Subwoofer amplifier circuit diagram. this circuit makes
only Bass. we can use this circuit for the woofer. it includes a
lowpass filter. we need this to make a 2.1 sound system. here
use the sunken 2sc2922 and 2sa1216 transistor to make the
sound strong. we also can use 2sc5200 and 2sa1943 transistor.
we can use 25-0-25 voltage to 50-0-50 voltage and 5 amperes.

The transistor 2SA1216:
The material of the transistor is Si
The polarity is PNP
The maximum Collector Power Dissipation is 200W.
The maximum Collector-Base Voltage is 180V.
The maximum Collector Current max is 17A.
The max operating Junction Temperature is 150 °C.
The transition Frequency is 25 MHz.
The Current Transfer Ratio (hFE), MIN is 33.
The transistor 2SC2922:
The material of the transistor is Si
The polarity is NPN
The maximum Collector Power Dissipation is 200W.
The maximum Collector-Base Voltage is 180V.
The maximum Collector Current max is 17A.
The max operating Junction Temperature is 150 °C.
The transition Frequency is 25 MHz.
The Current Transfer Ratio (hFE), MIN is 33.

This circuit doesn’t have speaker protection. here need a
speaker protection circuit. here is the link to get the speaker
protection circuit. Diagram is here.
This is the Speaker protection circuit diagram. It can protect our
Speaker from the burn. if the amplifier has any problem then
this circuit can save our soundbox. Normally when the transistor
makes a short circuit the voltage comes out from the speaker
output line then this circuit protects that voltage. This circuit
should not allow any direct voltage to be sent to the speaker.
This circuit is very important for protecting the speaker.
