You say that you are looking for accurate mids and highs? Well, maybe a wide range driver could get the mids right, but if you have ever have seen a spectral analysis, you would see how much distortion/resonance is present - that many of us hear. Sure if one needs bragging rights (my driver can ...), then maybe the fact that acoustic pressure can be created over a wide frequency band is enough. Where music needs the most power, the full range drivers are most anemic.
So, if one uses those drivers only where they can do a decent job, maybe 500 to 7000 Hz, then it could be OK - if one could integrate something above and below.
If you seriously read this site, you will see that full range is ok for Bose wave radio level stuff. For the demands of high quality playback, there are too many caveats. This website is a remarkable diary of Romys search for good sound. He ended up with a large 5 way front loaded horn speaker that is the exact opposite of a single driver scheme. The rest of us have also shared various attemps, successes and failures.
At the end of the day, we all do what appeals to our own sense of what is right.
