Small Audio Power Amplifier Using Op-Amp and Two Transistors
https://www.deeptronic.com/electronic-circuit-design/small-audio-power-amplifier-using-op-amp-and-two-transistors/
Using two small transistors (2N3904 and 2N3906), we can build small power amplifier which deliver several hundreds milliwats. The basic circuit is a totem pole transistor pair with small biasing circuit configuration to give small leakage idle-current. Let’s see the schematic diagram of the circuit in the Figure 2.

Assembled Small Transistor Audio Power Amplifier. For some simple applications such as toys, intercom, or small gadgets, there is sometimes a need for small, simple, low cost, or low voltage solution of power amplifier circuit. For this requirement, high fidelity is rarely needed. A modification of amplifier circuit from Bowden’s circuit collection is presented in our article, …

Mono amplifier two speaker outputs using transistors. In normal stereo amplifier is 2 speakers. And if a mono amplifier is a single speaker. But this circuit is a special Mono amplifier. It can drive 2 speakers at the same time. Without parallel or serial access. Because It causes the impedance of the speaker changes.

https://electronics.stackexchange.com/questions/97827/best-transistor-to-use-for-audio-amplifier
Transistors are used in audio amplifiers in different ways. You have discrete class-a circuits that overdrive well like the infamous Neve console mic pre. On paper an op amp designs will have the best performance (actually putting separate transistors in front of a conventional op amp is probably going to get close to the theoretical limit of performance).
