B&W 803 diamond series 1 vs 2

I've had a pair of 803 diamonds since 2012 that I acquired  from a friend.

 How would I go about finding out what version they are? I tried using google and am not seeing any comparison threads on series 1 vs 2. Mostly talk of the new 803 d3 compared to the d2.  Thanks in advance. 

Couple of cosmetic differences between D1 and D2 other than improved crossover, 

  • Version 1 does not have silver rings on the main woofers and tweeter 
  • Version 1 does not have magnetic grills

Hope this helps!
