Sure works for me and in every case I've done it the speakers and LP are at a room odd harmonic and the more it is in 3D the better, more seamless the response. Once I understood this, it became obvious that ideally at least one sub per dimension was required and even though Drs Geddes, Toole have published multi-sub papers, folks continue to mostly put speakers, subs where convenient/WAF approved and at most, use room EQ to even out the worst of it, usually with mixed results.

I just spent some time EQing and tweaking and watched some of my favorite action scenes from the fast and furious series. I'm thinking my next sub build might just have to be for my surround system to upgrade my little 8" Sony....whatever it is. Sooo....can I borrow one of yall's budgets? Just for a minute, I swear! 😀
Can you post screen shots of the inuke dsp tabs? Make sure you don't have multiple low pass filters. If you're using a processor that already low passes the signal, you need to turn off the low pass filter in the inuke dsp.

Things are getting confused here. And I hope we will not see any more posts containing direct personal abuse.
Whether or not the thing being called the reciprocity principle works in theory, I think there are more caveats that should be raised in practice. But the basic question is the relevance of that method to the task at hand. Are you looking for the good location for your seat or for your sub?
Some of the researches being referenced for justification have to do with ensuring the best possible sound over the largest number of possible seats (for example in a recording studio with folks standing, sitting, and in all states of inebriation). The researchers like Toole and Olive (if I recall correctly) tried various sub location and various mic locations (and sometime various opaque stats criteria).
Here we are trying to make the sub or subs sound best at typical one or maybe a few locations that - in the usual circumstances in life - are defined by the layout of the home. The subs can be shoved around and even put behind furniture, in closets, and hung on walls. But the issue remains choosing sub location(s) that sound best at the specific seat(s).
Finding a good sub location is the end of the task with my approach. But with the reciprocity method, you are just at the start when you have completed your mic survey of the total room.

It's OK to be critical, even very critical, even totally critical of some posted idea. But it is not OK to call somebody an idiot.
It is positively rare to hear any apologies here.
GM -
Sorry that it wasn't clear I was referring to the earlier nastiness (that others also complained about), not to you. I am sorry if anyone looked (unsuccessfully, of course) for the abuse in your prior post.

Normally I would agree with you totally. But when you try to ridicule a suggestion to use commonly-accepted process that you don't understand instead of simply asking about it, you basically "open the door". Next time, ask, instead of acting the fool and then complaining about being called one.
The very fact that you are actually asking that question just highlights that you still do not understand what is being discussed.
Ben,
1) The reciprocity principle is not just theory, it works perfectly in practice, and is relevant to anyone who does not want to endlessly move a sub about the room in search for the "best" response.
2) Usually both locations are somewhat limited, so the compromise between the two is what one looks for, after the usual "stereo imaging" has been achieved or discarded along with other audio basics because of logistic compromises.
3) Correct, which is why the reciprocity principle is used- for a single sub. When utilizing multiple subs, reciprocity is no longer a simple process, as there are multiple interactions between the room modes and sub distances from each other and the mains.
4) Since the reciprocity principle starts with the sub in the listening position, after you complete the survey of possible sub locations simply moving the mic and checking for "best" response, you have finished the process other than moving the sub from the LP to the proper (or most logistically acceptable) location.
OK?
Cheers,
Art

I'm completely agree with this, but the punch is not all the time the same thing for everybody.
Listening to the subwoofer only you can not hear too much punch.
You have to listen to the whole spectrum from a full audio speaker system to make a decision whether or not it has enought punch.
I have generally used 1/3 octave equalizers or parametric EQ using a combination of RTA, SMARRT (a dual FFT system) and my ears to determine balance and best phase response through the crossover region with the location compromise chosen.
