B&W Nautilus 804 - how good are they

I don't like the treble balance of the B&W line for the most part. If you listen, try to listen below the tweeter, more on the mid axis to do it justice.

IMHO the Monitor Audio Platinum line has a much more neutral tonal balance throughout, but for many it would be too laid back.

I have found all B&W speakers to be too bright for my taste.  You will not ever get soft highs with a B&W speakers   

Agree with the above — given your tastes you’re barking up the wrong tree here.  Buy these and you’ll be much happier…

The Nautilus line is not representative of current models of B&W.  They are more relaxed on the top end and actually present a very nice sound.  I'd say go for it if the price is consistent with used prices.

When Diamond tweeters were introduced, their tonal balance shifted.  The Nautilus is the last line before this introduction.  There is a reason the Nautilus line (especially the 802) still holds strong values.

I have the diamond version of 802 and 805 and I do like their sound - especially for classical music. They might be geared towards that (not sure but many seem to agree that they do classical well). 

They can be found in many recording studios and there must be a reason for that as well.

Speakers are personal so you got to hear them and love them, although researching and asking questions are also good - let your ears be the final judge, preferably with your front end (especially the amp section).

The 804`s are fine for a 22x13x8 room. For a larger room you describe, I recomend the 803`s, or 802`s.

Lets make the price point under <$1,800 for discussion purpose. 

No diamonds in this one:
