Every time you open your mouth, you impress. You are correct. Each stereo speaker requires equal lateral distance to its sidewall (preferably without obstructions). Confirmation came when I made the necessary adjustments. Screenshots with your fault finding is free schooling. We thank you 🎉

Thank you. It is not me that requires equal distance. It is a requirement of two channel stereophonic sound presentation.

That KEF system with the two big SVS(?) subs probably fulfills its intended purpose of sounding impressive with movies. I would make sure the subs are on isolation feet and try to get some treatment up on those walls. But also, in such a tight space, I would consider not using the center channel at all, unless they typically have people listening way off axis. When you're on axis, the center channel really isn't needed and if it's not vertically aligned with the left and right, I feel like it does more harm than good. At least in this case, it appears to be both the same kind of speaker and a proper point source. So, better than most.

Another example of quantity over quality.

Disagree profoundly about subs on a wall/boundary, absolutely the best thing to do provided you can EQ it. SVS advise corner placement for subs and they're absolutely right on that.

Speaker manufacturers know that most people want quantity over quality. Their goal is quantity since that is what people buy. Notice sub stacking. Room corners produce room distortions that increase amplitude. This increase in amplitude is room distortion.This distortion can be measured. If your goal is quantity then place your subs in the corners. If your goal is low frequency resolution then you must match the sub to the dimensions within the room and find a location that produces less room distortion.

The last one brings up an interesting discussion. Unlike the first two which seem to be 2 channel stereo system, the last one was more home theater. Center channel and two massive subs included. It would seem each has their own design criteria. With home theater wanting a really dead room and lots of speakers around you. While HiFi is only 2 speakers (more minimal sub as needed) and controlled ambience in the room instead.

You must match the usage to the room size. You must match the treatment to the usage.

I once lived in a room that had the shape of a "kicked" letter L. The speakers were placed at the junction of two rectangles. The left speaker stood 1.5 ft from the side wall with windows, and the right speaker stood 10 ft from the right wall with a large mirror (3 ft). There were no acoustic panels used in the room. How is it possible that in such conditions I managed to achieve holographic sound filling the entire room? Of course, this does not deny the positive impact of acoustic panels. I'm just curious how it is possible to achieve such good sound in such unfavorable conditions.

Achieving a soundstage with center image focus is not difficult to achieve. The resolution which includes instrument seperation and definition is much more difficult.especially in the lower frequencies. These qualities require treatment to achieve. Remember we have two main issues for treatment: pressure and reflections.

Listening near field in a small room is better than no listening at all. But listening near field to me is like looking at an oil painting close up. What loiks like a mess real close up, morphs into a beautiful piece of ar 12 feet away. For me, the soundstage and depth imaging doesn't gel unless you are 12 to 15 feet away from speakers.

Near field is less room sound, more resolution. Far field is less resolution more room sound.

I enjoyed near field listening when I had to. But now that I have a gigantic room, and am sitting fairly far from the speakers, when I lean my head forward a few feet the image just doesn't gel in place anymore. The instruments themselves sound more 2 dimensional; not just the soundstage. When I lean back again, that wonderful 3 dimensionality of not only the soundstage but the 3 dimensional of the instruments themselve, all of a sudden click back in. That's the best way I can describe it. The instruments sound a little too much like 2 dimensional carboard cutouts when I lean forward a few feet. The window with slats over it behind the speakers, when I first moved here, was playing havoc with the sound. Singers like Rickie Lee Jones you couldn't even stand it! So I had to move the speakers nearly 7 feet from the wall behind them to correct that. I do have quite a bit of acoustic treatmen on the side walls. My one speaker I can only get it about 3 feet from it's side wall. Because of how the room is shaped, the speaker on the other side is in much free space in that way. If you have 4 speaker terminals for biwiring on the back of your speaker. Try bypassing the bass terminals of one speaker, if your room has a bass peak. I had an awful one. It worked for me. I now have the best bass definition I've ever heard, and it's all coming from the left, where I have a subwoofer. Low bass is non directional and it sounds like it is coming from the middle instead of from the left of the room. It fills the room beautifully. Moving my speakers that far forward from the wall behingd them, necessitated using a subwoofer. I am very pleased with my acoustics now, and no frequencies are being accentuated that I can hear. It all sounds perfectly flat and even to me. Like your videos a lot! One of my favorites.

@@sidesup8286Im really curious if you can fix the phenomenon if you toe the speakers in a little more so that you experience the same amount of high frequency again. Can you please confirm if this is so, or if it really has to do with listening distance?

Any experience with panels & subs? Parallel to front wall, subs centered 😊 Yes, mid gear ⚙️ isn't helpful, 4' above rack

Sub positioning is directly related to room dimensions.

The 2nd and 3rd setups look like they were forced by their other half to move to the finished attic or the upstairs half-story, which is a shame, especially if they're the one paying the bills or most of the bills. (edited to reorder because I didn't account for the 4th setup) I really like near-field too, and if you're forced by your small property or your not being the alpha dog in the house to set up in a small room, then near-field is definitely worth trying, especially if your budget is limited, meaning you can't afford AF-quality room treatment.

What about magnepan speakers

Remember that the room only sees energy. The source of that energy does not matter to the room. In our experience these speaker types benefit from diffusion after reverb decay times are managed correctly.
