Also, the bases in the photo where speakers are black are different. One has some kind of support for the baffle, the other one does not (or it is an optical trick where my eyes cannot see the left one has support).
I also saw a black and red combo photo where the base was again different. I assume the final decision about the base is still not made or these are rendering from different phases of the project.
The red and black looks the neatest as there are now screws visible in the waveguide and the base is metal only (matter of taste of course).
