center speaker question

xfsrg

for a center speaker, should I go with component and coaxial. this is for my car, but it was recommended that I ask in this section. so in general, would strictly mid-range be the perfect choice or go with the mid/tweeter in one combo?

incase it matters, i am looking into a 4" speaker for my center channel in my car. it will most likely be placed where the cigarette ashtray would go. these are the two speakers im looking at.

By no having a tweeter for your center channel and going strictly midrange you will missing out on a good amount of musical information, I would personally prefer the sound and idea of a Component speaker, but if it comes to space, get the coaxial with the tweeter instead of having only a midrange speaker.
