Mini Subwoofer Circuit 22W
The subwoofer is a subwoofer or a speaker to reproduce low frequencies, devotee of 20 Hz to 150 Hz electronic circuit diagram below shows the details of a scheme of the main amplifier TDA1516 22 watt in 4 ohm car subwoofer driver. This device is designed for an existing stereo amplifier, often requires adding another blow to the music of driving a subwoofer.

Subwoofer Filter with LM741
The acoustics of converting a filter, near are many aspects of the financially viable possibility of the further famous are Baxandal filter low and soaring frequency filters and crossover Acoustic area is transformed into subordinate-domains, so with the purpose of the Thursday Speakers. Applications, we offer a filter, the limits of the region to transform acoustic (20-20000Hz) happening the region of 20-100Hz.

The make signs on behalf of a head high pass filter C1, C2, P1, which is undesirable level DC input. A lowpass filter consisting of R3, R4, C3 prevents frequencies on top of 10 kHz, which look after not benefit from this design, and it would come about so as to the instability and clatter. The precipitate amp invert make signs.
The low Summary of the amplifier signals extend to a next low-pass filter to prevent the frequency from the speakers.
I unambiguous, a second order, because this box with a bunged place bring out. If you give birth to a circuit with a valve coordination, and therefore simply close the Wind (Roll a pair off of socks and pick by the docks / Wind), this preference bequeath you a sealed box as a replacement for.

TL072 Car Subwoofer Filter Circuit
Here is the circuit diagram of an easy subwoofer filter that can be operated from a 12V DC supply. Such a circuit is incredibly helpful in automobile subwoofer applications. The circuit is nothing however a low pass filter whose pass frequency can be adjusted between 60 to 160 Hz.
The circuit is designed based on the TL072 dual BIFET opamp IC. Out of the two opamps inside the chip, IC1A is wired as a buffer. The left and right audio inputs when mixing is fed to the input of the IC1A using the DPDT switch S1. Switch S1 is the part control switch which can be used to create the subwoofer in part with different speakers. When S1 is in position 2, 180 degree part shift will be induced.POT R7 can be used for controlling the level. IC1B forms the low pass filter whose pass frequency can be controlled by adjusting the dual gang POT R13.

Description
The TDA7293 is a monolithic integrated circuit in Multiwatt15 package, intended for use as audio class AB amplifier in Hi-Fi field applications, such as home stereo, self powered loudspeakers and Topclass TV. Thanks to the wide voltage range and to the high output current capability it is able to supply the highest power into both 4-Ω and 8-Ω loads. The built-in muting function with turn-on delay simplifies the remote operation avoiding on-off switching noises. Parallel mode is possible by connecting several devices and using pin11. High output power can be delivered to very low impedance loads, so optimizing the thermal dissipation of the system.

600W subwoofer audio amplifier
Skema Rangkaian 600W subwoofer audio amplifier - This picture below is about my setup subwoofer amplifier with 20 CH mixer and parametric. This amplifier use transformer 10 ampere to supply the power and 3 ampere transformer use to supply mixer and parametric.Elco capacitor that i use for the transformer 10 A, only 10000uF numbered 2. The circuit of amplifiers that i use which is 600 watt mono subwoofer amplifier . And booster amplifier only use 2 Sanken transistors. See picture subwoofer amplifier assemblies below :
