I'd like to see another color, if that is an option, before passing judgement!
I'm not real keen on those, but I don't think it is the lines. I think a darker color (maybe gunmetal) for the main body would work better with the silver and black baffles.
Edit: Looks like this is the only other option.
Definitely better. But I think silver baffle, gunmetal body and black woofer baffle would work better.
Now the name..."Concentro"?
What's up with that? Did they misspell concerto? At least "Concentribbon" would reflect the use of a concentric ribbon tweeter!
