Woofer speaker circuit diagram

A Subwoofer is a loudspeaker which produces audio signals of low frequencies. The first subwoofer amplifier was developed in by Ken Kreisler. It is basically used to improve the bass quality of audio signals. Here we design a subwoofer amplifier producing audio signals at low frequencies from 20 Hz to Hz and with an output power of W, used to drive a 4 ohm load.

In this post we learn to make an active loudspeaker system circuit for enabling self sustained amplification of any music source that may be directly plugged in to the active speaker box. With the advent of ultra modern cell phones, now it has become possible to store huge music data and listen to them with just a flick of your finger. By amplifying a small music signal from either a cell phone or similar source and hearing it over active loudspeakers can become more interesting and the outcome simply amazing.

Complete design idea and schematic of a simple speaker amplifier is produced here. A normal loudspeaker may be a 3-way type with the connected amplifier equipped with the usual bass treble controls etc. No matter how good they may be in their performance, they can never beat the sound quality that is normally achieved through active loudspeakers.

Building an active loudspeaker system may look complex but can be very amusing, and once built can indeed become a treat hearing its magnificent response. Although the cost involved compared to its passive counterpart is much higher, an active system has definitely a clear edge over the passive systems.

The various advantages of a built in speaker amplifier over the passive design may be listed as follows:. No use of passive filter circuits using resistors and inductors means an increase in the overall efficiency of the output response due to the absence of power losses through heat dissipations generally involved with passive filter resistors.

Unlike passive filters, the active filters help to boost the set responses. Here we will discuss one such active loudspeaker circuit, capable of transforming even an ordinary music inputs into outstanding reproductions. The following points will discuss one such speaker amplifier circuit, capable of transforming even an ordinary music inputs into outstanding reproductions. The idea is very simple, equalize the inputs by passing them through appropriate lo-pass and hi-pass filters at the input stages, then amplify this dimensioned content to suitable high volumes using ordinary amplifier.

We do exactly as mentioned above; referring to the figure we find that a single IC TL which is basically a dual op-amp in a single package is discretely configured into two separate filters. IC 2A is wired as a standard high pass filter. As the name suggests, the circuit will pass only specified degree of high input frequencies. The cut off frequency may lie around 3 kHz and can be varied by adjusting VR1 and VR2 or any one of them.

IC 2B is wired in just the opposite configuration i. It will stop all frequencies above this. The response is adjustable using VR3. The above suitably equalized audio now is simply fed to an audio amplifier for the required amplifications over the connected loudspeakers.

The channel responsible for producing higher frequencies uses a twitter for better optimization where as the other section which handles the lower frequencies is integrated to a woofer for the relevantly bass output optimization.

If you have any circuit related query, you may interact through comments, I'll be most happy to help! Your email:. Please send me reply on this as I would like to make this Loudspeaker as Bluetooth with proper power cord to get proper music from any devices including Cellphones etc.

I understand your problem, however, sorry, I do not have any details about Sanyo SS speaker systems. Good day sir. I am new to electronics, but I am also fascinated by audio amplifiers. I have collected a few old car stereos and was wondering if I can use the power amp circuit to make an amplifier? I have downloaded the data sheet for the ic, however i do not know what to so with the mute and the standby pins.

I tried to learn about the standby and the mute pins in the datasheet, but I could not find any such pins available on the IC?? Hi, Surely the circuit as drawn is nearly correct and the woofer and Twitter are connected to the correct outputs.

Please comment. Thanks, You are absolutely right, it seems I did not concentrate on the diagram while replying the previous comment from marife..

Hi Sir, correct me if i'm wrong, you have mentioned above that IC 2A is wired as a high pass filter yet it was feed to a woofer at pin 4 and IC 2B wired as a low pass filter and was feed to a twitter at pin 6.

Should i interchanged the two driver? Hi Marife, yes it's a mistake, just swap or interchange the woofer and the twitter positions for correcting the fault. Hi Sir, in the diagram above what is the correct value of capacitor connected across ground and pin 5 of TL?

Could u please tell what is the difference between a 3 way speakers being driven by an amplifier with tone controls for bass and treble , and the active speakers? Looking at the construction of the active speakers its looking same as having equiliser circuit followed by an amplifier build into it. Please let me know if my understanding is ok or not.

In active speakers we have separate amplifiers with corresponding separate active filter modules for the relevant attached speakers woofer, twitter, squeaker. The design provided in the article has followed the above mentioned concept and has employed separate amplifiers for each speakers, therefore it is a good active speaker system.

Today I am going to an audio amplifier using mobile charger. We can also use wastage of charger. We will need only transistor of mobile charger and also we can use 1K resistor of the charger which is connected to the LED indicator. Firstly we have to connect all components according to the circuit diagram as shown in the picture. Question 1 year ago on Step 1. Hello, my name is Julian. I am almost finished with this project. I would like to thank you for sharing it. But I am curious as to any information about the speaker you can share?

Subwoofer Wiring Wizard

This is basically a low pass circuit which is used to separate out low frequency sounds from audio signals at audio play back devices. A simple loudspeaker is not capable of reproducing all the frequencies of the audible range. Different kinds of loudspeaker are available which can reproduce the sound at certain range of frequencies. Tweeters are the kind of loudspeakers which are used to reproduce high frequency audible sounds and woofers are the general term for the loudspeakers which are used only for reproducing low frequency sounds. In an audio playback device at least the low frequency signals are required to filter out, amplified and fed to the woofer and such kind of circuitry is called bass separator circuit.

This speaker crossover calculator will help you design a set of amazing sounding speakers. It'll tell you what capacitors and inductors you need to create a passive crossover design for either two speakers a 2-way passive crossover or three speakers a 3-way passive crossover. In the 2-way mode, the calculator uses the impedance of your tweeter and woofer to produce a 2-way speaker crossover design. By choosing three speakers, it becomes a 3-way crossover calculator, in case you also want to incorporate a midrange speaker into your design.
