hello, i have a onkyo home theater reciever with a passive subwoofer. wondering if someone could recommend a simple yet effective single channel amplifier circuit i could build to get some thump out of it. i had no luck tinkering with different built in settings. thank you!

 

Hello,

On the projects page of ESP, you will find several circuits:

There are subwoofer processors and amplifiers over there.

Use a TDA2030 ic http://ampcircuitschematic.blogspot.co.uk/2011/04/tda2030-complete-tone-control.html?m=1

 

An amp such as this is likely better and cheaper than anything you could build.

i always like the challenge of building my own circuits, but this may be the way to go. thank you!
