what differentiates in 2/12 way and 3 way speaker ?

Earlier, I posted this too quickly and in error:

Imagine a 3-way with 2 woofers.  If the crossover rolls off one woofer to mate with the midrange but rolls off the other at a lower frequency, it becomes a 2 1/2 way.

Here are two correct alternative re-statements:

Imagine a 3-way with 2 woofers.  If the crossover rolls off one woofer to mate with the midrange but rolls off the other at a lower frequency, it becomes a 3 1/2 way.

Imagine a 2-way with 2 woofers.  If the crossover rolls off one woofer to mate with the tweeter but rolls off the other at a lower frequency, it becomes a 2 1/2 way.

kr4, my speaker have one tweeter, one mid and 2 bass identical, Ar my speaker the 31/2 way or 21/2 way ?

Depends on the crossover network.  What speaker is this?

kr4, speakers are ML 60 xti.

"The Motion 60XTi measures 48”H x 11.4”W x 14.4”D, weighs 66 pounds, and, along with its FMT XT tweeter, has one 6.5” midrange and two 8” woofers in a three-way configuration. The tweeter hands off to the midrange at 2.2kHz, while the midrange and woofers transition at 400Hz. "
