I feel as if I'm on a hiding to nothing, but here goes: Why would that totally distort the waveform?

Phase distortion

You should build one on a prototype board and inject a 80 Hz sine wave on the input , then look at the output waveform on a scope

As anyone with any knowledge of these matters knows, the particular SHAPE of the soundwave on a scope does not relate to the SOUND of the wave to the ear.

I've don't said anything about the sound, but evenless how it sounds this is very subjective, S.Linkwitz was considering that 100Hz was the threshold of audibility (as i remember)
At 80Hz it seems that you are in the audibility zone, with very low efficiency loudspeakers in a reverberant home environement.

Thanks, that's what I thought you must have meant. It's a shame no one responded to Siegfried's request to test their findings and audibility.

Is that some way to weasel out of your post and double-talk? We only care about the sound not the pictures on your scope.

Perhaps that no-one have a good enough sounding room for that.

Yes, the sound of the signal.
