I write this review after six months of useage of this pcb with pair my old box type Onida tv speakers. It very compact and very small in size but noise quality is awesome. Sound output is very clear and disturbence free. For higher volume sometimes small distrubance came other then that it works very well. I also connected 100k potentiometer as volume adjuster with this pcb. This is good for 2.1 small home speakers with normal volume output.
