Ya know.. this is a matter of personal taste. Kinda like tennis shoes. Some like Nikes, some like ADIDAS, others Reebok. They are all good in their own ways but everyone has their preference.
Of the prior speakers listed, I sell MB Quart, Boston & JL Audio. I will never talk bad about a line I do not sell because it is not proper. You never look intelligent talking shit about another brand.
I can tell you that if my opinion matters, Focal is the best line of speakers for a car. From their lowest line speaker to the highest, their entire line is better than most brands at the same price point.
Having sold just about every line of speakers that has ever existed for a car, I haven't had a line that was better engineered overall.
It seems as though some manufacturers make a good high end speaker but miss the boat on the lower line stuff. Then, other manufacturers build a decent lower price speaker and then all their high end stuff sucks.
Every single one of Focal's speakers at whichever price you pick is my favorite at that price.
Oh well... that's it.
Just another opinion of course.
