Crossovers are not superior they are an intrinsic problem in which success is measured by the least damage done. High sensitivity is also, when are other aspects are equal, superior. Issue at hand is what sacrifices must be made to achieve results.
Problem with FR is that they are never full range and they misbehave at frequency extremes. If you cant hear this then you are the one with the problem as the design is intrinsically flawed in this regard. Running a midrange or midbass driver full range also limits output. Add to this the problems with dynamic drivers and you get a better more objective view of the issues involved.
Sorry but your attempts to "dumb down" these complex issues just dont hold water. Too many experienced members on this forum to buy into your gross oversimplifications and inane generalizations. If there was one ideal speaker this would be the speaker all of us would own.
No more Friskies for you!
