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?

The anechoic and/or quasi-anechoic measurements people are used to seeing are supposed to be flat.
In a room you should have a descending response from around 100-150 Hz. This is what all of the automated room-correction software tries to do, more or less. They don’t attempt a ruler flat response for exactly the reason stated by the OP.


There are some other things going on in tweeters I'd like to mention though.


B&W and some other "high end" speakers use a ragged tweeter response designed to elicit a sense of detail. This is a trait I blame Stereophile for hyping/promoting as "neutral." It isn't.


Brands which shy away from this kind of tweeter trickery are Magico, Vandersteen and YG Acoustics.  However, that doesn't mean the rest of their response is ruler flat/accurate either. Just that they at least don't try this hyper-detail trickery.  Of course, I call it trickery, you might call it a wonderful feature. :)


Having said all this, I also find that the floor area behind/between the speakers is an unexpected place for harshness in a speaker sound. If you have a solid floor or rack between the speakers, it’s worth experimenting with blankets/pillows in the area.
I find that the most natural and comfortable to listen to speakers are the ones that employ some subtle version of "The BBC Dip".

Highly revealing, spacious, well done lower slope crossovers, fast, tuneful, all of it, with a slight BBC Dip. Clean and warm, as the mix demands. A properly done BBC Dip, in my design experience....has the lowest part of the dip centered around 3.5khz and then goes back up again, and is about 2db deep, overall, as a best potential compromise.

And then it’s good all around and it can play all day, at any volume. From soft to break the windows levels...

Everything else that might be off.....is generally just bad equipment choices. (It is a multistage learning curve and individually committed to as an act --same goal, and very probably a different path for each person)

This graph has it as being slightly exaggerated but warming up to being ideal.
This would come down to personal preference and likely room response as well. For me, I am not a big fan of this design technique, though the reason to implement it, to invert the peak in the Fletcher-Munson equal loudness countours and "soften" the sound makes sense. From a methodology standpoint, it is similar to the "loudness" setting that boosts bass response at low volumes where we have poor sensitivity to bass. It is sneared at in audiophile land, but there is a solid reason to do it when you can’t turn the volume up.  I would not be surprised if there was a variation in the level of dip in the loudness contours from person to person.

This means you should never think that a studio monitor speaker is even remotely suitable for neutral and balanced home use. They are emphatically not.
B&w, pmc, atc, kii audio, etc many are used for both.

That curve is about what I normally do with digital eq to "tame" my loved ATC 150asl somewhat. Maybe up to 4db around 3,5 khz where they cross to the tweeter. Except for a flat response in the bass.....

Can't really agree that most pro monitors are especially exaggerated in the highs (above 8 khz). Maybe they are just not rolled-off and a little more direct in their dispersion. Most often they have controls to take down/roll-off the treble. NS-10 of course very special. Made only to work with the mids.
