What kind of towers? By "pointed roughly at my ears," do you mean a near field pc setup? Not all towers or speakers work as near field monitors, IME, or toed-in, for that matter.
As someone who has historically chosen larger, monitor type speakers, I took it for granted that all speakers could work up close like that, and I was mistaken. Once I started getting into different speaker designs, I found that the spaces I tend to inhabit and the way I like to listen up close to my systems, actually favors the monitor types. Other towers I have, I thought were flawed, but actually worked fine pointed more straight and as a whole room speaker.
Reason I ask is, a good near field is incredibly immersive even as a 2.1 setup. So much so, in fact, I never care to consider atmos or even 5.1, for music, or desktop videos/gaming.
Just trying to understand (i'm not into movies/tv so I really don't know) what would drive people to keep looking further into more and more audio effects, or it makes me wonder if something might be missing from the main speakers to start with before looking further. That and, friends I have that are HT junkies with dedicated surround sound rooms, have since implemented their own 2.1 music systems in other rooms of their homes after sitting at mine. Now they chat me up in the evenings with song selections from sitting at their pc based near field systems while their HT is mostly unused during the week. They had no idea that 2.1 was even a viable way to listen anymore, and thought it just a budget, or all-in-one trivial/ghetto way to get music at a computer desk.
A well implemented 2.1 near field is a step up from headphones, with SQ, SPL, and in the immersive sense from my experience. Only reason I mention, or ask is, because I had friends give up on optimizing their systems because they thought they needed more channels and speakers to contend with today's content. That and for those with limited space/convenience with regard to multiple channel systems and gimmicks, that there are still uncomplicated ways to get totally immersive sound without headphones.
