reminds of that time I went to the Klipsch forum to find someone to take measurements of this thing at 115db 1m to see what headroom might look like....I was not well received. As the one person whos spent some time on the topic
Headroom. Neither have enough to truly cross at 250hz and remain true (undistorted) to true peak at high volume.. I personally am treading water with a ~150hz horn at 200hz and a 48dbLR, using 115db/1m as a benchmark.
Nevertheless. I agree with the point that a large system doesn't have to be void proper polar response. Actually large systems are needed to get the directivity people are looking for.
If you are using IIR filters (only), then could you show us your resulting excess group delay measurements due to those two HP/LP 48 dB/octave filters? A step response would also be instructive to see.

I may have found what you referred to above...
Well, you certainly impressed Mike (an acquaintance who owns Heritage Jubilees):
Jubilee thd @ 115db/1 meter ?

What's a dsp automatic eq do more than a standalone classic eq, eventually parametric? Your fingers should be following your ears ...
An auto eq in the sound engineering side is just a dynamic eq with a 1/3octave, neutral threshold.... just like any dynamic eq, whatever signal makes it past the threshold is attenuated by the multiple filters placed in the spectrum... they have some other features but its just, to me, the best version of a dynamic EQ, based around a 1/3 octave neutral threshold. Dynamic eq does not attenuate the whole signal like a wide band compressor. It just attenuates parts of the spectrum based on how you set the filters up and how much level is in the signal vs frequency versus where the threshold is set.
