On a MacBook Pro 15inch Retina I find the sound output from the internal speakers to be quite 'strange'. It is like there is too much bass from where the spectrum starts and then as if there are some kind of gaps in the spectrum where middles and highs are somehow absent or underdeveloped.
These are small speakers and they are usually judged as quite good for their size. Yet they seem to me part of the wrong side in the loudness war.
Besides the cumbersome setup of this surely outdated solution: On these newer machines I cannot arrive at a satisfactory result.
But I remembered a few "audio optimizers" offered some speaker correction presets for these machines. (Examples would be Boom3D, Hear, eqMac2, Bongiovi DPS…) With the smallest settings I found Boom quite smooth. But that piece of software is unreliable in operation, costs money, and offers a range of other features I do not want or need, and it is even accused of possibly damaging your audio hardware if misused. On top of it the results on this machine are not in that way 'better' as I remember it (and re-tested with an older version just now) from older machines.
Since I am lacking even the right terminology for this kind of task:
How do I approach speaker correction for this machine properly? Are there equalizer presets to start from? Settings perhaps to download somewhere or to copy along the sliders of the band?
Can these speakers or their response curve really be calibrated (as the setup from one of the software titles seem to suggest) Other software solutions to consider altogether?
Note that I am aware of "perceived sound quality" as pretty much opinion based, therefore I am not asking about "the best setting" but about the proper approach to this problem in general. The huge difference between the so called "optimized for this machine" settings offered by Boom and Bongiovi DPS is testament to the "opinions differ" thing as well.
