Single driver speakers. Are they worth considering ?

There is coherency in single driver designs that eliminates quite a bit of IMD due to crossovers. A heated up crossover can cause compression, particularly the bass/midrange crossover, and bring a hard presentation if driven. I personally appreciate the immediacy of full range drivers. Dynamics are less affected and again, as a preference, dynamics are on my list of highly desirable characteristics. 
I guess one can tell I like to crank it!

Looking at an article form Sublime Acoustic they noted that "the capacitor and inductor values drift with temperature. When you turn up the volume the values will begin to drift, which causes the effective crossover frequency and other characteristics to drift, which  can lead to distortion of the sound."
Before purchasing my speakers, I probably spent 6 months reading about speaker performance and concluded that if all possible it would profit me to eliminate crossovers as much as it is possible to do so.
