With the tweeter assembly open, we get a better look at the vented, horn-loaded tweeter that gives the HomePod its "precise" sound.

The vents on the sides of the voice coil bobbin and the four holes at the rear of the tweeter prevent air pressure from building up behind the tweeter dome as it moves.

Reduced pressure saves the dome—and the music—from distorting while the tweeter moves back and forth several thousand times each second.

So far we haven't seen any evidence of diamond tweeters ... Any answers for us Dr. Geaves?
