4:58 - Thank you! Glad to finally have someone agree with me. The key is of course the Center speaker "done right"..., which is all too often NOT the case. Done "well" maybe, however done "right" (as in very very well) often the Center speaker is not. As well I'll add that for Stereo music listening utilizing a Center speaker not all Preamp processors are created equal and therefore a 3.1/7.1 (or 3.2/7.2) setup can sound substantially better with a Preamp processor doing things rigjt/better (which also provides the adjustments to get the setup right).
Combined Measment of speakers in different locations at especially at higher freqiencies will be affected by combfiltering because of the wavelengths and distance. Higher frequencies spaced out greater than their wavelength will have greater combfilltering effects where the phases will superimpose positive and negatively with its multiple harmonics. We in the pa/sound reinforcement industry do measure multiple speakers in multiple speaker arrangement such as column and j arrays, in groups. I get what the person was saying. You still have to compare each speakers response in the room and see how their individual response are reacting throughout the room and see how best we can get even response throughout the room. You still will have variations, hence why allot of hometheater purist strive for all speakers being sonically being of the same speaker, to achieve an even room response. So the best is just a comparison between all your speakers.
I’m confused. A while ago I asked you about the pros and cons of virtically stacking 2 pairs of identical speakers, creating a column array. You responded, something to the effect of, ‘don’t do it. You will experience major anomalies with comb filtering which will seriously impact the integrity of your audio reproduction’. Yet, in this video you explain that comb filtering in a stereo set up is normal and nothing to be concerned about. How is comb filtering an issue in certain scenarios, but not in others?
Comb filtering *at* the speaker (like 2 stacked) is not the same nor perceived the same as combing between 2 channels. The latter is normal stereo effect, some mild coloration and an elevation error (upward). Nothing objectionable.
I recently asked your advice on virtically stacking identical speakers. You strongly advised against it because of issues with comb filtering. I appreciate that advice. Then, in this video, you state that some comb filtering in a stereo set up is not an issue, normal, nothing to be concerned about. Would you be kind enough to expand upon that. Why is comb filtering an issue in certain scenarios, but not in others. I’ve taken on board how comb filtering manifests itself, but can’t grasp why that manifestation should occur when identical speakers are virtically stacked and precision aligned. You did suggest that I was a little aggressive in the way I asked my last question. Aggression is not my intent. I’m merely hoping to expand my own understanding by tapping into the knowledge of someone with a more profound understanding than myself.

Great topic!
Fun video as always. I also suffered this problem you described before being helped by another to understand.
Always Interesting, So I Keep Listening!
I appreciate that!

I wish I could give you tons of likes while you give us a tutorial on subs integration. 🙂
One could argue that if music was mixed in stereo the coloration has already been taken care of.

@@ajsoundfield9652 that was the message that came across, but with no explanation, which is what I’m seeking.
Great video!
Thanks!

Thank you for supporting my channel! I'll be recording a video and answering your question shortly.
Interaction comment! Does this still count? 😀
Meaning BACCH crosstalk cancellation should be future standard.. and good directivity speakers should be priority..
Is this a priority technology or can it be done via known DSPs such as MiniDSP, HypexFusion...?
