Everyone will have their opinion when it comes to speakers and positioning etc, but think about it this way... would you wear headphones lop sided? On one ear but not on the other? And expect to hear 100% of their performance and ability?
by failing to place your speakers correctly, that is in effect what you are asking them to do.
you could spend all the money you want, but if you don’t put them on your ears you aren’t going to hear them.
same applies to speakers and positioning. If you don’t create the soundstage, how are you ever going to hear the potential?
spend a million on sound and stick your head in sand, all you will hear is sand.
It would be nice if you'd considered there might be some truth to my reply, instead of claiming it's the same as wearing headphones incorrectly.
Take this Danley speaker, for example:
https://www.danleysoundlabs.com/products/loud-speakers/synergy-horn/sh50/
It's not a small box, that's for sure, but it'll be a good illustration of my point.
Speakers like these are designed to put sound only where you want it. As you start to move outside of the coverage angle (in this case, it's 50x50 degrees, but there are other coverage angles available), the sound drops off very quickly. Because of the design of the thing, they manage to pull that trick evenly across most of the frequency range. ie, from a few hundred Hz upwards, the sound is being sent out towards the listening area, but very little is being sent directly sideways or backwards where it'll interact with the side/back walls.
Compare that with a typical 6" 2-way HiFi speaker. Those end up basically omnidirectional below 800Hz-ish (ie, lots of room interaction), directivity narrows as you move up, and then the tweeter comes in at about 2kHz and they end up almost omnidirectional again.
Not only do typical HiFi speakers throw lots of sound at nearby surfaces (which seriously disturbs the stereo image - it'll tend to collapse down to just hearing the speaker locations), they do so in a manner that's uneven with regards to frequency. ie, the overall tonality of the speaker in the room is strongly dependent on those nearby reflections.
The Danley speaker linked above would be just fine positioned near walls etc, because it simply wouldn't interact with them.
Just because you haven't experienced the benefits of controlled directivity speakers, it doesn't mean I'm sticking my head in the sand.
