Is it possible to make a low sinewave not saturated ?

I'm pretty sure it's caused by the wave cycle crossing from plus into minus.
A saw wave would sound like a click, but a sine just sounds like a fluctuation of some sort.

At the slowest crossing 0 happens 40 times per second... are you sure it is the fluctuation you hear?

Well I'm sure there is a fluctuation of some sort. I won't claim to know what causes it.
I don't really notice through speakers, but headphones, yes.
Even now, decades later, with studio headphones, I still notice it.
If I remember right, you have to go lower than 40hz of something to notice it

Yes actually it was about my speakers

Thanks everyone

Probably intermodulation distortion and lack of headroom in the mix. Trying to use clean sines in the lowest audible octave is usually more trouble than it's worth unless you're doing sound design for a very large audio system.

You could simply add a keytracking highpass and lowpass filter. Vital would be perfect for this
