This question has been hanging in the bat cave of my mind for some considerable time, so I have decided to ask it.

What is it that would cause an audio engineer to prefer, not specific to any model as far as I know, the 10" woofer to the 12" and the 14" to the 15," as has often been mentioned here?

#2. I assume the comment that the 150xAL woofer series is the first fifteen that is not geometrically challenged is related to the question above.

Thanks in advance.
