The choice of 3 - 14 Ohm drivers is because of the combined load (4.6 Ohms) on the servo plate amp.

The servo plate amp could not drive 4 - 14 Ohm drivers. Aggregate impedance (3.5 Ohms) would be too low.

SW-12-16 parameters:

FS 28.3Hz
BL 14.07
Mms 108g
VAS 100L
Qms 2.8
Qts 0.85
Sd 490cm^2

X-Max 16 mm

Ideally, you would want even numbers of drivers to cancel out non-lineararities of the forwards and backwards cone movements.
