LM386 amplifier is good for audio applications and the load impedance must match the output. Generally, if you want to connect the loud speaker make sure that the load impedance is within the limits.
As per the datasheet of LM386 datasheet, it is mandatory to maintain impedance between 8 to 32 ohms. Hence the impedance of loud speaker must be within this range.
You can go through this article for actual working of LM386 as audio amplifier

That article and schematic do not agree with common knowledge .
