As much as I like to talk about my speakers, this is perhaps not the best place for that.Yep, as You said. Advertising--at You website, isn't meant to be a scientific publication. I still think this state of affairs is a pitty. Fair enough, though. Amps, I always thought this case is settled. I personally cannot imagine to question my humble AVR, if my goal is to just fancy me with interesting musical presentations. It does the trick, so what else to expect? More detail? Not really ... More volume would entertain my neighbours next street ...
I think our little conflict is settled. As I, for the time being are not that much into "imaging" with stereo, I can't appreciate audio systems that claim for themselves to be superior in this respect. For whatever reason. Would You mind to link some scientific sources here anyway?
Last, to tell that Your subwoofers are technically "horns" is a bit of a hyperbole. Just my impression. Performance still is pretty much o/k for the formfactor.
It is not only about imaging. Having very good early reflection attenuation increases clarity, gives better instrument separation, preserves the room information from the recording better.
Some systems project images - small images - of the instruments, accurately placed in a 3D-landscape. This can be fun, but it can also be questioned whether this is accurate and true.
Then you can have imaging that presents some objects very sharp and accurate, while other objects are big and diffuse - there is huge contrast.
Some audiophiles choose to place the speakers as far away from walls as possible, others choose to install large horn systems. They both try to minimize early reflections - though the resulting sound experience is very different.
So reducing early reflections as much as possible and having a controlled decay for what happens further out in time, will improve sound quality.
We can find support for why this is so theoretically.
In an article/thread I try to describe how acoustics are fixed in a small room. Look at the measurements, and compare to your own room, if you are able to do similar measurements there. The owner of this room wrote a brief impression, which I find is quite good at describing what this is about and how bit relates to sound quality: https://www.kvalsvoll.com/blog/foru...coustics-for-a-f205-system/?part=2#postid-237
