Subwoofer booster circuit is used to enhancing or boosting or increase the subwoofer amplifier, but it also can improve the quality of the bass sound on an amplifier or High Power Amplifier. Subwoofer booster circuit/bass enhancer circuit based on the IC 4558 and TL074 or commonly known as IC op-amp, it's suitable to be a boosting in subwoofer system, which together with some components.
Part List Subwoofer booster circuit:
R1=22K, R2=100K, R3=220R, R4=220R, R5=220R, R6=10K, R7=4K7, R8=1K, R9=20KTrim, R10=150K, R11=22K, R12=20K Trim, R13=4K7, R14=2K2, R15=220R, R16=220R, R17=180K, R18=22K, C1=4u7/25V, C2=10uF/25V, C3=220uF/25V, C4=220uF/25V, C5=1n2, C6=47n, C7=47n, C8=100n, C9=100n, C10=4u7/25V, C11=330uF/25V, C12=330uF/25V, IC1=JRC4558, IC2=TL074
For this subwoofer booster/enhancer circuit using voltage of 12 V +, 12V -, and ground. To be in accordance with the power of the speakers and amplifiers, the Subwoofer booster circuit/subwoofer enhancer is also equipped with a subwoofer volume setting on the R9 and R12 use 20 K ohm trim. Issued a circuit of subwoofer output is quite high, making it suitable for some speakers.
Updated Circuit and PCB Layout Subwoofer Booster using 4558 and TL072:

is -12v connected to ground ?
yes.
no is asymetric power supply needed
can u give me a description about the connection board
can u give me a description about the connection board
can u give me a description about the connection board
No i dont have image about the board
Please send me the pbc layout in my Gmail account abriedoor@gmail.com
i dont have pcb layout for this subwoofer booster circuit
thanks you for your valuable information
Hello ashik
Youre wellcome
In sub woofer booster circuit component ....IC2=TL074 .... some ic number missing so pls help me frds
In a number IC2=TL074 there some no missing...i need full no and details about IC2=TL074
In a sub woofer booster circuit components ........ R9& R12 are timmer resistance or timmer capacitor ...help me
Actually its same as NE5532
The R9 and R12 its Trimmer Resistance
hello sorry for the eror's on the schematic, i'm updated the schematic include pcb layout for subwoofer booster
hello ebin, you can see clearly schematic circuit diagram subwoofer booster on end post. if you have proteus, you can download the schematic and layout for more detail connection board.
you can see now, the pcb laout subwoofer booster.
download lingk error
if you want to download proteus file, please sign in google account before.
I can't saw a photo in this post
I can't saw a photo in this post
Please refredh again
can you plz explain what is the function of VR1 and VR2
the vr 1 and vr2 is for adjusting frequency low pass filter. is abaout 50hz - 150hz
Mas Wahyu yg ganteng, saya dah bikin tuh rangkaian. Saya punya speaker aktif 2.1. Dah saya pasangin giga bass sebelum tone control tp saya belum puas di subwoofernya. Kalau mau saya pasang di speaker aktif saya, urutannya gimana mas?
setelah tone control, seblum power mas.
Sir,
Output and input have only one line in pcb layout
Sir,
Output and input have only one line in pcb layout
yes it just one line, mono subwoofer booster
Sir,
Subwoofer have two line
you must make it two kit for stereo sir.
HELLO I WANT YOU TO HELP ME WITH A TL074CN I HAVE IT IN CIRCUIT THAT IS FOR TWO SATELLITES AND A WOOFER BUT I WANT TO MODIFY IT FOR TWO SUB WOOFER.
THE LOW OUTPUT SIGN IS VERY HIGH FOR MY SUB WOOFERS THAT YOU WOULD RECOMMEND ME I WANT YOU TO SLEEP LOWER HUB AND LOWER AS IN SOME SYSTEMS THAT BRING A GROVEE BUTTON YOU KNOW HOW YOU COULD DO THANKS
Hello,
if the output is too high, you can modify the circuit by replacing c8 and c9 100n with 470n. you can try it.
this circuit can be using on 2 subwoofer, what the njmber of your amplifier?
tks for include Proteus file
nice project
okayy thanks dude, hope you enjoy in here.
