You'd do well to get them from the link posted above (millionbuy)
Here's the deal with components vs. coax:
The advantage of a component is that it allows you to install the tweeter wherever you want. That can be a good thing, especially if you're willing to do the sort of install work that would capitalize on that capability (i.e., sailpods, a-pillars, etc.) You can move them around and decide where it sounds best.
But that doesn't always mean components are better. In some instances, coax is actually better because the sound originates from the same point. That cuts down on differences between pathlengths that might normally take a bit of time-alignment to nail down. Some manufacturers are starting to recognize this (and also that many people don't or can't do extra work on their cars) and building convertable sets or high-end coaxes. There is still a stigma that coaxes are "low-end," but there's much less truth to that statement than there once was. Case in point, Morel Integra Ovations, a coax that would make mincemeat of most components.
So, the question is this: In your install, do you plan to mount the tweeters somewhere else? If you don't see yourself glassing or cutting panels, and your car doesn't already have a place to mount tweeters, a better set of coaxes might be exactly what you're looking for.
The Pioneer Revs are good speakers, and they don't cost a lot. If you want good tunes for every day driving, they'll fit the bill and then some. With a bit of sound deadening, they'll definitely sound great and will surprise you.
No, it's not the cornerstone of am IASCA competition system, but it's all a matter of what you're looking for.
