50 hz booster circuit for subwoofer

jaya000 said:
I saw subwoofer amplifier with 18db 50hz bass boost.
I want to know about the circuit design of the same & wish to make one myself.

If all you want is 50Hz boost, use an equaliser circuit.
Just build one circuit for the one frequency.
If you want a circuit to correct for bass deficiency, then I recommend the correction circuit Linkwitz developed.

I got the circuit.
Now i want to know more about this circuit design.
I think U5- A is used for 50hz boost purpose.
What formula is used for this?
If i want to change 50hz boost to 70hz?
