How can I tell a B&W 804D (series 1) from a 804D2

Is the dust cover (bullet) on the midrange driver silver (D2) or black (D1)

It's Silver. (D2)
HOLD EVERYTHING!!

I think I've figured this mystery out.

the 804D (series 1) review in Stereophile was done in 2013.

Yeah, and the pictures in the review clearly show the D2 drivers, but there is NO mention of being a Series 2 at all in the article.

Was there NO 804D2 at all? The 804D clearly has the release date of the Series 2 and series 2 upgrades. My Linn speaker matching software does NOT give a 804D2 option, only a 804D. The other 800 series speakers have D2 versions to choose from.

I think it went like this:

804D (but released way later during D2 time frame and with D2 upgrades),

804D3,

804D4.

Normally the D1's came out in 2005, the D2's had to be 2010 maybe??

For some reason B&W would not give the 804D the D2 designation. I think that is why everyone selling these is calling them a 804D2. (that actually describes what it is way better than calling them 804D).

Answer to this is that a 804D (series 1) is actually a D2 in age and engineering, but it just got stuck with the 804D (series 1) name.
