Help me solve this speaker distortion issue

I've been composing with some piano libraries lately, trying to achieve a very dark sound. I noticed that every time I would play the dark piano, no matter the library, I would hear some slight distortion, which I have never noticed before.
There is no distortion when listening to other music, both soft and loud, everything sounds like it always has to me. Also, with headphones I notice no distortion anywhere.
I hear the same slight distortion in a piece like this: YouTube
But not in a pice like this when the sub synth hits: YouTube
The latter I assume is because high frequencies are masking the distortion, whereas in Dream 3 or the pianos I play there is nothing on top.

So now my theories are two:
- my speakers are damaged
- my speakers used to be better then me, but now my ears graduated and started noticing their shortcomings

What do you think? Have you had this happening to you?
I have a pair of JBL LSR2328P coming out of my Apollo 8.

I don't hear any distortion. Could it be the piano sound is exciting/buzzing something in the room?

Can you record the distorted sound so we can hear it?

You are right, I forgot to include some very important details.

There is nothing buzzing in the room. The room is pretty much empty, and I'm 100% sure the distortion is coming from the area where the speakers are located, where there is nothing but the speakers and the stands. I can distinctly hear it coming from the left and the right speakers.

This is where it gets weird: the closer I get to the speakers, the less noticeable the distortion becomes. Could there be some psycho acoustic explanation to this?

I have uploaded some samples:
- one from monitoring position (roughly 1,5 meters from the speakers)
- one with the mic up close to the cone, about 2 inches away. This is level-matched to the first one
- the first file with a bandpass filtered centered around 2k, the range where I hear the distortion
- the second file with the bandpass filter. Notice how, though the non-filtered file was level-matched, the distortion is less noticeable here
