Just a couple of minor points. The number of drivers has no bearing on the frequency response of a speaker. There are examples of multi way speakers that are out performed by single driver types.
Power handling has nothing to do with how loud a particular driver is with regards to bass and treble speakers. A driver that is 86dB 1 watt 1 meter will require more power to produce the same volume than a driver that is 95 dB 1 watt 1 meter.
Most single driver speakers will image much better than most three way speakers because they don't have the influence of the crossover.
There are some incredibly cheap three ways and some incredibly expensive single driver speakers and vice versa. Cost doesn't seem to be related to the number of drivers in the box.

Kyle, I am aware, which is why TYPICALLY is used in my post.

Compare speakers of the same sensitivity, then compare power handling. Multiple drivers typically allow for a higher power handling, or better headroom.

I disagree. I have not heard a single driver outperform a three way speaker at the high-end level, with 'Hi-Fidelity' (not by personal preference) as the approach. Some may be 'sweeter' than others, but not necessarily honest and accurate.
Cheap or not it depends. Do compare speakers whether 3 way or two way of at the same reference point- or same brand.
Hi-Fidelity is like being faithful to your wife despite temptations isn't it ") ?You may like the sound of something else, then there's nothing to compare, and it becomes subjective. In a Hi-Fidelity system, it's about referencing to a transparent system where the recording is most accurately presented. In a Preference-type of system, its about personal taste and it becomes subjective.
While the cross comparison happens all the time, it helps when you know the difference in sound before deciding. Tubes have a inherent hormonic distortion that ppl like-TYPICALLY. They usually don't have a flat frequency response, but sound thicker on the mid and highs, even high-bass. Enthusiasts enjoy them, and buy them, change the tubes and such. Listening to more details, and experiencing more depth. But in any frequency curve, when that happens, it ain't gonna be 'neutral'. Speakers have that trait too.
That's being objective.
Where sub is concerned, my opinion is that it helps with the bass response. Imaging will be better if the bass came from 2 speakers instead of 3 or 4. The position of your sub will somehow be the position where the drums or double bass, or pipe organ will be in your imaging. Sometimes, by 'helping' with the bass, the 3 way speaker performs better on the mid and highs, when set up properly.
