Again back in product protection mode.
Read again from Texas Instruments, far more authoritative than you Ralph, and this is still with the output filter in place, but with it set too high, without it and you have a tweeter meltdown.
From Texas Instruments:
On output filters of Class-D amps that are set too high corner frequency.
"A concern with the switching waveform being dissipated in the speaker is that it may cause damage to the speaker"
This is what happened to my mates Wilson 8’s above, as Wilson does not use a Zoble Filters on it’s tweeter and I on any of their speakers tweeters.
