Midrange performance from coaxials?

[a_hol06]

Question is how good of midrange performance do aftermarket speakers give? How good do ones with woofer and tweeter give, and how good 3 or more way speakers with small midrange do? been looking for coaxials that use midrange as primary and have a tweeter in middle, or is that what is already what is used in speakers?need some help.

coaxs are usually used stock, comps are better, but require more pwr

[a_hol06]

so do components use midrange drivers? do the tweeters have to be powered separately, or are they wired together as component? Wondering if id need 2 or 4 channel amp to power component.

2 comps use a 2 channel
