IME, there is less to the driver count of a speaker than the designer's skill. I have heard multi-way systems that are great, and some that stink. Ditto for two-way towers. But a designer that knows what he is doing can get excellent, extended sound out of a two-way tower. And, IMO, that's what you are paying for, not just the cabinetry and components, but also the artistry of the designer. Let's put it this way: Which would you rather have, a two-way tower for $6K that is the best speaker you've ever heard, or a 3-way (or 4- or 5-way) tower for $4K that sounds just okay?
I would focus more on the audible results rather than how many drivers are crammed into a box. The only time these become a practical consideration is in relation to the size of the room, the amp driving them, and your preferred volume levels.
