Bright High End Speakers = Bad Room?

I often get the impression that a good deal of the members on this forum appreciate to be fooled by a speaker being non-bright on bright recordings, that is quite rolled-off in the highs. They seem to call it musical. And name other speakers more true to the recording bright. Then there are speakers that are more bright than they actually should be, which may be fine as a working tool identifying problems in a recording. The end result of course a lot depending on the room and the listening distance. 

Speakers that are very 'revealing' are often considered to be bright. 'Bright' speakers have become something to fear and avoid. I refer to many of them as 'clear'. Padding a speaker down in an effort to flat line on a chart can/will soften the sound by removing detail. High end audio is high resolution. If the speaker is capable of sounding natural at a high resolution then I find it to be wonderful clarity. Why remove detail that you've worked so hard to attain? However, it will be critical of poorly made recordings. Over processed music out of a high resolution speaker can and will sound edgy. Good recordings are amazingly clear and sound incredible when done right. 

Good quality headphones are extremely clear. I began use them as a baseline for the clarity of my speakers. This put me on the 'bright side' of neutral and I much prefer it.

Agreed. Don't want the speakers to do the eq-ing. There are other tools for that where you actually know what is done and only when it's needed.

It all come down to enjoyment.  Even if you sit there thinking to yourself, Wow, these speakers are really accurate, how wonderful!, if you cringe and shudder even time the massed violins come in forte, then there's not much point to it, is there?  In music, emotional enjoyment > intellectual enjoyment.

Pro speakers for recording rigs in studios with consoles (64 channels, etc) are designed to be bright, or chosen for their unnatural brightness...as a form of revealing what is put in a mix. So that it is spotlit and thus manipulable, workable, mutable, changeable. Where slight changes in the recording can be heard. It is purposely exaggerated and unnatural.

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.

Neutral speakers for mastering, is another thing altogether.

This is true most of the time, so much so that it is a logical maxim. There will be exceptions or people taking exception with such statement. Sure. Whatever... But it is very much a norm in recording studios. Horses for courses.

NS-10 speakers from Yamaha, for example... are trash. Utter trash, and not suitable for home use or balanced listening to actual recordings in your home. Unless one is a masochist.
