This seems like a needlessly aggressive and poor take. Its a cool bug that they discovered; but going into "Apple's audio engineering team is, at least on some level, incompetent (or incompetently run; I'm not blaming the employees here, but rather the organization)" is just unproductively mean.

"and obvious in a sine sweep frequency response test, which is the most basic test you can run end-to-end on a completed audio system to ensure it is performing properly. So they didn't even run that." The one conclusion you can draw, outside looking in, is: whatever tests they ran resulted in the creation of the best sounding speakers on any device in its class. That doesn't scream incompetence to me; it screams "We tested this against songs people will actually listen to, not 300hz sine waves."

This post is a bad look for Asahi.
