B&W 804 D4 review and measurements by Stereophile

[Jukebox]

Courtesy to mr. John Atkinson and Stereophile we have the measurements of the new 804 D4. For many this speakers could be the best bang for buck in the 800 D4 series and the one with the most upgrades compared with the older model (reverse wrap cabinet; down fire port + plinth, new spider for the midrange, aluminum back plate...etc).
Now the look I personally consider beautiful, the sound is not for everyone but some aspects of the measurements are very interesting, like the very low impedance, the great rigid cabinet, not so great port resonance and of course somehow excessive high frequencies.
Didn't tested them personally yet, should happened next week.

yeah because they sound awesome, so if you don't see it you won't know how bad they are ;) I didn't imply they have to sound bad because they don't measure flat. Probably they can sound great.

Really good nonresonant cabinet. But horrible frequency response. Putting a tweeter on top of a loudspeaker is a really bad idea indeed. But nice looking speaker.

I saw the discussions there but now that the review is online I thought it deserve a separate discussion for this model only.

At this price point, measurements aside, I'd really appreciate it if drive units were completely centered in the enclosure.

 

[Puddingbuks]

I just don’t like B&W. Too mainstream, and mediocre performance for a lot of money.

I have to applaud JA1's attempt to reach new levels of diplomacy:
"The Bowers & Wilkins 804 D4's measured performance is enigmatic"

They cost how much?

Bah humbug from me, but if this was a BBC Thin-wall model or an ATC/PMC, they'd be absolutely roasted to a cinder (domestic PMC's do mimic some of these characteristics I think), yet being B&W with all the hi-tech facilities and expertise at their disposal, this dreadful performance is somehow excused as 'enigmatic...'

I think JA should get out his old M801's and do an appreciation of how good B&W used to be.....

That may be so, but it's visible in the pair photo as well.

Horizontal directivity is quite smooth though compared to other newer B&Ws so with some EQ it can be probably made to sound more neutral.

It's a render. companies don't photograph things anymore lol

Are you sure? the image shows one of the biggest crossover mismatches i have ever seen.

Good grief, there are a lot of overpriced horrors on the Stereophile reviews. No wonder Bowers sell so well.

I am totally sure, everything is relative, just look at these B&Ws in comparison:

True, but that plot only goes up to 60° off axis which can be a bit misleading

Seems like the best thing about D4 its the D3 are going to lower his price..

That’s quite a roundabout way to say they’re pretty crap
