For that I think you would be better of building a dedicated subwoofer amplifier, or using a tone control circuit. Though its better if you do…… But if you search in Google with the name of the project you will find the script…… Just copy and paste it.

Is the ic LM n will be the same kind or lm38n6-1.

I wanted to make a portable speaker out of an old speaker datashdet I bought a couple of months ago and your circuit with bass boost was exactly what I needed. I just updated the images to show the positive side of the cap leading to pin 5.

However, after one donation, you are able to donate again only after 3 months when your body has regained the donated blood. I understood from your other tutorials that C2 and R1 act as low pass filter. I have watt speakers if they are okay with the IC LM or not????? The idea is to put another capacitor as close as possible to pins 4 and 6 to maximize the decoupling.


You can connect two speakers in parallel. Sanath on December 23, at 3: Hiii…i made my own circuit that works with 8 ohm speaker, but i want to replace it with datasbeet 3 ohm speaker…is it possible? I really enjoyed this tutorial and this would really help me a lot in my experiments. This is the best project with an LM I have seen in the Web, for many reasons — very professional and cool, and yet easy for newbies.

DevRoy on September 5, at 4: Boss, this is the best circuit i have ever seen. Maybe 10uf on input and uf on output. I built this according to the information above, and double-checked the schematics in the LM datasheet, but for some reason I do not get a change in volume when adjusting the volume potentiometer.

Hi Bruno, you can run the LM at 12V without a regulator. The minimum voltage rating is 4V, so it might not work. The bass boost and the gain pots are not connected to ground. It is asking me to write a programme.


Andrew Gravlin on May 15, at 9: As in this circuit the input dwtasheet directly connected to a op-amp, input decoupling is a must. Algen on May 14, at 8: Louis on November 28, at 1: Be sure to subscribe to keep updated on our posts as soon as they are published.

Will you be kind enough to email it to me?

Build a Great Sounding Audio Amplifier (with Bass Boost) from the LM386

One of those caps is a 0. So the input signal will get oversteered fairly quick.

On the presented circuits an important capacitor is missing, the source input cc decoupler. S Prakash Rao on July 11, at 2: Florence on October 24, at 6: Anthony on September 16, at 8: This was just what I was looking for.

NOME on December 30, at 1: DungFung on July 29, at 6: Will on December 19, at 7: Arslan on April 3, at This would allow me to hear what should be the lowest and highest volumes quickly, rather than gradually.

The circuit operates at 9V, so any capacitor voltage rating above about 16V will work fine. I am doing datashdet to attempt to convert from 9v to 12v.
