speakers have a low impedance, typically 8-Ohm. Even for a low-power 0.5W audio amplifier, PIR 2 /2 requires that the amplifier must be able to source a peak AC current of around 350 mA with an 8-Ohm load. This is a lot more than a typical op-amp is designed to provide. For example, the LM358 and LF353 (two op-amps used in this lab) can source
