I am soliciting opinions on the the desirability of retrofitting a pair of JBL L-100t's to use JBL LE14A LF drivers.

The cabinet specfications for the L-100t's and the 240Ti's are as follows:

L-100t
Internal Net Volume = Between 3.3 and 3.4 Cubic Feet (Apx.)
Port Size = 4.1" ID, 5.25" L
LF Driver = 2214H

240Ti (Courtesy Giskard)
Internal Net Volume = 3.5 Cubic Feet
Port Size = 4.1" ID, 5.25" L
LF Driver = LE14H

Is the internal net volume of the L-100T's close enough to the recommended internal volume to allow the LE14A driver to work properly?
Would the retrofit improve the quantity and quality of the bass?
Would the general quality of the sound improve?
How does the sound quality of the LE14A compare to the LE14H?
How does the sound quality of the LE14A compare to the 2214H?
