I couldn't tell if that article was being serious, or was meant to be a joke. Let's assume it was serious ...
On acoustic suspension .... that came across as an ignorant rant. The implementation matters not, only the results. Whose speakers measure the lowest distortion? Magico. What loading do they use? Acoustic suspension. Case closed, rant negated, article launched towards garbage can.
Class-AB or Class-D are idle much of the time, and even listening to your music loud, the average power is quite low. If you want to rant, rant against Class-A heaters, not against a speaker that is most of the time getting less than a few watts average power .... the article, now circling the rim of the garbage can.
I didn't record the grand piano in my room, I recorded it in a concert hall or studio. I am not trying to create the sound of a grand piano playing in my room, I am trying to recreate the sound of a grand piano playing in another room. That whole paragraph is just mindless bloviating in an attempt to look erudite and relevant. The article now drops fully to the bottom of the garbage can.
Page 2? ... no, already put the trash out to the curb.
