Audiokinesis pretty much has it nailed. The only thing I would add is that there are some advantages to going MTM rather than TM for a 2-way. It's a set of trade-offs, but with an MTM you have the advantage to splitting the "work" from 2-3K on down among 2 drivers. Since it's really hard to do a good 2-way with mid/woofs larger than 6.5-7 inches, you have a hard time getting a lot of bass SPL's out of them. Adding a second driver allows for more bass, and if you listen at somewhat louder levels, lower distortion and less voice coil heating. That said, it's usually better to go TMW 3-way if you need the bass and SPL's.
Advantages of multiplying drivers?
Can anyone briefly explain what are the advantages /disadvantages of multiplying drivers (Triangle Magellan, Tyler Woodmere to name a couple) vs. more traditional designs (1 tweeter, 1 medium, 1 woofer)?
My intuition would be to allow for better vertical imaging but at the expense of integration and since this is the true Art & Science of speaker building, why would anyone flirt with the disintegration risk?
