Personally I think those frequency responses are a load of crap. 35-35? I call BS. It might be able to reproduce a single frequency in a sweep, but I doubt it can handle all that at once. Pluse, if those are door speakers, you'd typically want to have your crossovers around 80-100Hz to keep the 'woofers' from damaging themselves.
Speakers, in my opinion, are something you have to hear and compare for yourself. I, personally, don't like Alpine speakers. They sound too 'tinny' to me, and I prefer Polk. However, I know plenty of people who don't like my Polks, but prefer Alpines.
Not a great scientific answer, or perhaps not even really relevant, but I threw my hat in!
