Subwoofer booster circuit with PCB Layout
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.

is -12v connected to ground ?
ReplyDeleteno is asymetric power supply needed
Deleteyes.
ReplyDeletecan u give me a description about the connection board
Deletecan u give me a description about the connection board
Deletecan u give me a description about the connection board
DeleteNo i dont have image about the board
DeletePlease send me the pbc layout in my Gmail account [email protected]
Deletei dont have pcb layout for this subwoofer booster circuit
Deletehello 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.
Deleteyou can see now, the pcb laout subwoofer booster.
Deletethanks you for your valuable information
ReplyDeleteHello ashik
DeleteYoure wellcome
In sub woofer booster circuit component ....IC2=TL074 .... some ic number missing so pls help me frds
ReplyDeleteActually its same as NE5532
DeleteIn a number IC2=TL074 there some no missing...i need full no and details about IC2=TL074
ReplyDeletehello sorry for the eror's on the schematic, i'm updated the schematic include pcb layout for subwoofer booster
DeleteIn a sub woofer booster circuit components ........ R9& R12 are timmer resistance or timmer capacitor ...help me
ReplyDeleteThe R9 and R12 its Trimmer Resistance
Deletedownload lingk error
ReplyDeleteif you want to download proteus file, please sign in google account before.
DeleteI can't saw a photo in this post
ReplyDeleteI can't saw a photo in this post
ReplyDeletePlease refredh again
ReplyDeletecan you plz explain what is the function of VR1 and VR2
ReplyDeletethe vr 1 and vr2 is for adjusting frequency low pass filter. is abaout 50hz - 150hz
DeleteMas 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?
ReplyDeletesetelah tone control, seblum power mas.
DeleteSir,
ReplyDeleteOutput and input have only one line in pcb layout
Sir,
ReplyDeleteOutput and input have only one line in pcb layout
yes it just one line, mono subwoofer booster
DeleteSir,
ReplyDeleteSubwoofer have two line
you must make it two kit for stereo sir.

ReplyDeleteHELLO 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,
Deleteif 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
ReplyDeletenice project
okayy thanks dude, hope you enjoy in here.
Deletecan i use this circuit for a 50w amplifier
