transformers/output impedance

Hello,
I'm confused, or is it a question accepted that the use of output transformers for tube amplifiers, aims to lower the output impedance of the same, to match with the impedance of the speakers? However, how can a passive device (transformer) influence the output impedance of an active amplifier unit? I say that the output impedance is a characteristic of the amplifying machine, and transformers only optimize the ratio of its ability to deliver current, with the current requirements of the speaker, easily translated by its impedance

Thank YOU,
In your example, we say this
is a transformer 1-50? The final voltage, after transformer will decrease 50 times, but amperage will increase 50 times. The power (watts) will remain the same.
The same power, but with an lower output impedance?

Thank you all,
Is nice that when I start this thread I was thinking in preamplifiers, even if I did not say, because it was easyer to introduce the subject talking about amplifiers.
Now I can say, The more we learn, the long we know the way is
