Upgrade from B&W 802D1 to Focal Utopia Scala Evo

all measurements are from the center of the woofer:

mine are 8' apart, each are 4' from the side walls, and 3' from the front wall. Room is 16 x 21 x 6 feet (finished basement, carpet on cement floor.

the 802D's soundstage was massive routinely extending past the sides of the speakers. Vocals were also more focused and defined. However, instruments are very loud and pronounced on the Focals

How does designing a speaker that takes 500 hours to break-in, make it a good design?

Only speaking to your comment on the theoretical of 500 hours ... good design. 

I would doubt break-in is a target for speakers... but what they sound like is after breakin. A minimum life of a decent speaker system is 20,000 to 30,000 hours withiout noticeable degradation... many can easily go much longer like over 50,000. 500 is not much. I can easily see it happen if the target is very tight sonic qualities then very ridged materials is what you would start with and those materials may take a long time to reach optimum pliability. 

very true. but how does that make it a good design. it seems to me that if a speaker takes that many hours to sound like it should that it is basically a crappy  design

Look at the converse, we compromised the sonics of the speaker to avoid breakin. So, you have a speaker that doesn't sound as good. This is a highly competitive businesses. So you compromise the sound to say our speaker has less breakin required. Design is all about constraints.
