I don't understand what you're accusing me of. My plot shows the original measured impulse with the original polarity (red trace), along...

I am not accusing you of anything, I am just saying your graph presents a suitably time shifted impulse so as to show a min phase...

I agree that a speaker indeed follows a f^2 relationship due to mass control but is a mic diaphragm not designed to move with velocity...

Cool then. But that deems your time shifted graph below wrong because it attempts to show a min phase response: while my inverted...

"Relevant to discussion" would be an explanation of why you think shared sub measurement's response is minimum phase because it's NOT...

I am curious what your definition of excess phase is. Mine is "any deviation from the minimum phase response". Poles and zeros occur in...

The mic is inverting it during measurement acc. to this experiment:

:) That seems a bit forced to look min phase and peaks in the opposite direction but more importantly does not explain the excess group...

ART for the Monoprice HTP-1 has been in beta for 1000 years now.... DTS:X Pro was supposed to come shortly after. I feel sorry for the...

True, maybe they are not minimum phase or maybe it's some boundary reflection leaked by suboptimal anechoic conditions. Maybe @j_j can...

The response is not minimum phase according to your measurements, see excess group delay compared to minimum phase version even after IR...

True as with the wavelengths involved, the enclosure can be considered a point source but that property is nearly useless for all...

What John means there is excess phase group delay after removing minimum phase part of the response. It may as well mean "uncorrectable"...

My advice might go against the grain, but it’s backed by both data and experience (just not by the industry): For Atmos, always aim for...

I think what Levimax was saying is that to get 20Hz response from a 13" driver in a small box, a good deal of low end boost will be...
