And the crazy thing about that answer is considering the question it is actually pretty good. If you think lldd anyone can tell you the difference between two speakers based on size you might as well be asking to tell you the difference between an elephant and a horse. Four legs, two eyes, only difference is size, right? Nevermind the fact there are many different species of both, there is a world of difference between a Clydesdale and a Kentucky Walker. What is their profile?
There isn't one. You do not compare speakers like this. You want the largest speaker you have room and money for. That is the "profile" of size. Then you want the one with sensitivity at least 92dB that sounds the best.
As to that last point, do not dismiss that as "with each properly matched to their amp" as if you screw up and buy low sensitivity speakers that one thing alone makes finding a good amp a whole lot harder and more expensive. If there's one single thing to keep in mind that is it.
