class ab amplifier

hi everyone, I am a university student pursuing physics honours I am building an project in which i need to drive an sine signal on 4-ohm woofer from an function generator. so as not having that much core electronics background I studied some basic circuitry like building a power amplifiers...

Is there any problem of my circuit? How can I fix the clipping?

Hello I was looking at circuit to bias a class B amplifier in order to avoid crossover distortion and I found the circuit shown below. Can someone please explain to me how does it work?All biasing circuits that I've found in theory use diodes and resistors and I have not seen a circuit like this one
