Small speaker for a musical keyboard that does not have one

[Whiffle]

Hi there.

I am thinking of taking up piano and have got hold of a keyboard that does not have any inbuilt speakers.

It does, however, have a headphone output, stereo phono outputs and midi connections.

If I buy a small unpowered speaker, will there be enough power to run it? I only want to use if for a bit of practice (when headphone make the old ears a bit sweaty) so it does not need to be very loud.

Also, would it be better to connect the speaker to the headphone output or the stereo outputs?

Thanks

Thanks guys.

Just to fill in a gap in understanding - am I correct in thinking that headphone outputs have a little bit of amp power (just enough to run headphones), whereas regular 1/4" outputs have no real power and rely on active speakers for the output?

Really helpful - thanks very much.

One other thing I have noticed is that the L/R outputs have a separate output dial. If I connect an active speaker, what output would I have to use on the keyboard before then being able to control volume on the speaker itself.

I have often wondered the same, when I used to use a Raspberry Pi with Libreelec. I had separate volume controls for both the Pi and the connected TV and I could never work out which to use.
