Well, he's not wrong and he's not right. Overpriced yes, no good not really. They sound good in their own right, but for the same money you can probably do better.
Your biggest issue now is finding the right fitment for your car door panels right? Some other brand speakers might not fit properly without some cutting.
Btw, since it's a beemer, do you have a budget for this upgrade? What amps you have in your car now? You should consider changing to the specially-designed-for-BMW aftermarket speakers. I can't remember what brands they are but they fit exactly where the original speakers are including subwoofer so those are probably fitment-perfect compared to Alpines or whatever.
What car racun you la? If you're gonna compare with a 12-speaker Mark Levinson setup in the Lexus or the Dynaudio setup in the Volvo, all I can say is
good luck to you.
