Actually thanks to twoleftears ’s dog, this would be a great way for Class-D owners if they have a young’ish dog to tell if their output filter is set too high or too low, as they will be one the other, or combo of both, eek!
Just watch to see if they react when in the same room when you turn on and wait for the delay to switch on your class-D amp/s.
I would say if you get no reaction you’ll have the "set too low filter" and you have a Class-D that is not hard or bright at all, but I bet it’s number 2: of the above.
If they run out of the room or react you know it’s the high filter number 1: above.
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 this tweeter and I think all their speakers.
