I need to build an active crossover circuit for my 2-way speaker design. I decided to use TDA2009 as my audio amplifier. TDA2009 is shown connected below in the picture. My question is: how can I modify the TDA2009 circuit to implement the circuit in the gray box?
I know that C10 and C11 are need for the DC battery to minimize noise as well as C1 and C2 (2.2uF). So these 4 capacitors need to stay in the circuit. What about C4 and C5 do I need them? or I just connect the high pass filter of the gray box directly to pin 8 and 4 of TDA2009 and the low pass filter directly to pin 10 and 2 of TDA2009? What do you think?
Finally I need it to be active filter that is my TDA2009 need to be placed after the filtering circuit (gray box).
Please I need your help concerning this. I came to this forum after weeks of research because I am really stuck.
