This simple sub woofer circuit can be got easily, in general this circuit is also used for automotive audio such as car audio and speakers are indeed also have benefit in order to remove the noise more jarring, and also more not thin or jamming bass. The simple circuit sub woofer can certainly also make the speaker sound so is is more focused to see or listen to music as well as films. A moment of meaning as well as understanding of the subwoofer itself is a device that acts to lift as well as  capture low frequency usually has a frequency between 20Hz to 200Hz reach. The series is generally so additional electronics circuit in the speaker device is indeed more involved to raise and also lifting a low voice as the sound of the bass.
It is indeed a simple sub woofer circuit should remove noise that meet and also meet the general standards of human hearing. As well as of course it is recommended to produce sound at frequencies around the center. Do not be too loud any low that it can certainly make noise so less enjoyable. Speaker device indeed has its own limitations in the flow system delivers the sound in most frequencies that can not be reached by the speakers.

Active sub woofer is typically used to reinforce the bass sound to make it more "kick". And no less does the bass sound in the speakers active tend to feel less attractive even more treble. Of course this can be annoying. Not to worry, you can assemble your own version of the active sub woofer to get the bass sound more interesting. You can make the circuit using a power amplifier or type BTL Bridge Tied Load that uses IC TDA1516BQ components.

in the picture above the active sub woofer circuit schematic, the output voltage has a magnitude that came out 22 watts with 4 ohm impedance. And this circuit requires a power of 12 to 15 volts that can be taken anywhere with the use of an adapter or batteries. And also there exist a circuit schematic of the low pitch setting. Some of the features that can be used in this circuit are:
-  Volume button,
-  Phase button
-  Frequency On - Off

Below is the list of components require to make a simple subwoofer:

• P1 10K
• P2 22K
• R1,R4 1K
• R2,R3,R5,R6 10K
• R7,R8 100K
• R9,R10,R13 47K
• R11,R12 15K
• R14,R15,R17 47K
• R16 6K8
• R18 1K5
• C1,C2,C3,C6 4µ7/25V
• C4,C5 68nF
• C7 33nF
• C8,C9 220µF/25V
• C10 470nF
• C11 100nF
• C12 2200µF/25V
• D1LED
• Q1,Q2 BC547
• IC1 TL072;
• IC2 TDA1516BQ
• SW1 DPDT
• SW2 SPST
• J1,J2 RCA
• SPKR 4 Ohm Woofer

In the active filter sub woofer, amplifier needed Op-Amp TL072 IC that functions as an active low pass filter. Input L and R are combined and controlled by the P1 part of the level which is then converted into the volume control. While SW 1 serves to select the phase to be used. While on the power amplifier, using TDA1516BQ IC components that will enhance the signal that had previously been entered into the transistor Q1 as reinforcement before entering the power amplifier. Here's a little information about the active sub woofer circuit that you can assemble your self.
