Ok that makes sense!
What high pass slope is it?
If you know exactly the slope and type I can compensate for it.
Still better to remeasure though, if only to improve S/N down low.

Why are you using a high pass? Are you using a sub?
That would make things more interesting to correct using rephase, because linearizing the phase of a 24dB/oct filter at 2.2kHz is not likely to bring any audible improvement :D

You know your stuff! There is indeed a high pass filter set at 60 Hz and 48 db/oct. I forgot to turn it off. I use it for sub integration- sunfire true subwoofer mkiv.

Btw the speakers I've been measuring are not sealed- they have a bottom port.

Thanks!

Ok then just set the phase linearization settings to LR24 at 2.2kHz and LR48 at 70Hz (or so), and make sure the openDRC is placed before the loudspeaker/sub crossover (but I imagine this is already the case)
Then you have to be sure that the sub and louspeakers are at the same polarity.
Some further measurement (possibly with the loudspeaker's port plugged) will be necessary to adjust everything, but at least that should give you a near minimum-phase system. Adjustment will be limited as you cannot independently EQ and filter the loudspeakers and subs.
It could also be rewarding to processed to some minimum-phase EQ, but this require some more measurements (playing with gating and all).

Of course if you post impulse responses in txt or wav format, together with some contextual info (mic/speaker distance, distance from boundaries for both mic and speakers, etc) then I would be willing to help as much as I can.

Great! I plugged it all in and the low end phase looks much better. Im sorry I forgot about the sub integration filters!

I'll give it a listen and let you know how to sounds.

Thanks again for all your help!!!
