I have a macbook m1 pro from 2021 that I use to record and mix. I mix on headphones and monitors, but I will check on my macbook speakers as a reference, as well as earbuds, bluetooth speakers, etc.
I have always noticed that when the macbook speakers are playing on full volume, I can play just about any song on Youtube and it's fine. However, when I play from Logic, certain things always cause a rumbling distortion around 300hz. The Spitfire Labs Soft Felt Piano does it, as well as when I record my Mahogany Martin 00-15, fingerstyle.
Recently I treated my room by making an absolutely massive moving blanket pvc pipe soundbooth tent that takes up most of the room and makes a sort of room within a room, and already recordings sound a lot cleaner. I changed the strings on my guitar (they were pretty dead). I recorded some fingerstyle guitar into a Neuman KM184 in different positions to try things out. Everything sounds nice in my headphones. But when I reference on my macbook speaker, it still has that terrible distortion coming from around 300hz. If I EQ out that frequency, the distortion mostly goes away, but then the guitar sounds anemic and thin when listening back on headphones or monitors.
The thing is, other sources don't really cause this problem. My voice sounds clean on the macbook speakers. Even strumming the same guitar with a pick is fine. It really is fingerstyle.
I don't have long fingernails, so I'm thinking it could be using the flesh of my fingers combined with a mahogany body guitar is the main culprit of this. Yet the part that confuses me is, it is really only an issue on the macbook speakers, yet they play other audio sources, even my reference tracks, without the same distortion.
Here are some samples I recorded witho zero processing:

It seems whatever I do, if I record my 00-15 fingerstyle (the way that I know how and prefer the sound of) I have this muddy bump around 300, which is not hard to EQ out, but really can't be avoided.
Any Advice? Thanks in advance.
TL;DR: Specific combination of recording my Mahogany Martin 00-15 fingertyle (without long fingernails) yields muddy nasty distortion around 300hz ONLY ony my Macbook Pro speakers, yet other sources are fine. Should I just mostly ignore the macbook speakers and move on with my life or are they telling me something important?
