It's not only a matter of having better hardware (though it certainly helps a lot). For example, Apple does a lot of software tuning and tweaking to make the Macbook speakers sound as good as they do. And it's been fascinating to read the extent of work Asahi Linux had to do to recreate the software portion of Macbook's audio stack.

The problem is you need correction EQ built into to the drivers tuned to the enclosure (in addition to loudspeakers that are also designed accounting for their directionality, position, and the volume of the enclosure).

They should be able to offer a better trackpad module (and I've been hoping that they eventually do). The speakers seem like a harder problem to solve. The acoustic engineering that goes into designing a good speaker involves every element that can interact with the sound waves, not just the driver itself.
