Bright High End Speakers = Bad Room?


Long time lurker, new poster and diving right in.
I have noticed on the threads, a lot of what are considered high spend speakers, high end B&W's particularly, but not exclusively, being faulted for being "bright", a viewpoint typically garnered from "heard them at a show", etc.
I would posit that the reason this is, not exclusively of course, but in many cases, is due to a conscious decision in how these speaker companies balance on/off axis energy  (or an unconscious decision due to the space they were voiced in).

Whether it is assumed you are going to have more off-axis energy due to reflection/diffusion and/or assumed you are going to have less off axis energy due to absorption, if you don't implement your room accordingly, you are going to find the speaker bright or dark versus a speaker, even a low end one, that is voiced in a room more like the typical partially or poorly treated room.
Thoughts?

But there was one group who consistently preferred a flat response: Recording engineers. To them, speakers are a tool, and in general the more revealing the better.  
Do you have a link to the study that mentions this? Thanks
Toole conducted extensive double-blind listening tests and found that most listeners prefer a gently downward-sloping response trend,
what was the explanation?
" Do you have a link to the study that mentions this? Thanks "

He describes it in his book, don’t remember whether or not he included a reference. I’ll try to remember look for it this evening.

" what was the explanation? "

I don’t recall offhand what Toole said about it.

I have read that it may have to do with the absorption of high frequencies as sound travels significant distances through the air. At a live performance the distances involved would reduce the amount of high frequency energy reaching the audience, whereas the relatively short path lengths from instrument to microphone and later from speaker to listener do not attenuate the high frequencies significantly.

Chances are very good Toole’s test system was overly bright. Oh, well, back to the drawing boards. Shut the cave door and back to pigmy country! 
audiokinesis, we may be in agreement and we may not be.

A speaker that is ruler-flat on-axis, anechoic chamber, will have a typical room response that slopes off at high frequencies. It is this response, the room response that slopes off that people prefer predominantly. Generally first reflections will always be sloped as they are off axis. I copied pieces of my post below as I wanted to be quite clear that ruler-flat on axis anechoic response is much different from room response and it is room response that people respond to and determine as too bright.

In Floyd Toole’s latest presentation he heaps praise on a speaker with ruler flat on axis anechoic response. He also states in his excellent 00 paper on Maximizing Loudspeaker Performance the need for a "flattish, smooth, axial frequency response". His personal preference at that time was room friendly loudspeakers (i.e. most rooms).  Do you know when that first study was done?  If it was old, it could be an artifact of speakers at the time?

The real solution, for professionals as well as consumers, is loudspeakers that deliver similarly good timbral accuracy in the direct, early reflected and reverberant sound fields. This can be described as a loudspeaker with a flattish, smooth, axial frequency response, with constant directivity (which together result in flattish, smooth, sound power).

Floyd Toole, Bruel & Kjaer, and I all agree with Kenjit on that point.

Toole conducted extensive double-blind listening tests and found that most listeners prefer a gently downward-sloping response trend, both for the first-arrival sound and for the early reflections. Most people perceive a "flat" response to be "bright", and a gently-downward-sloping response to be "flat".
atdavid OP12 posts10-30-2019 3:14pmA ruler flat response on axis only matters in an anechoic chamber and/or listening very close to the speakers. The room response is likely to be much different which is what my post speaks to.I do not think overall that most people consider a ruler flat response too bright, especially since it is the room response they respond to, not the anechoic measured on-axis.
