The 14B-SST is a stereo version of the mono 7B-SST. The 14B-SST cost new about the same as a PAIR of the 7B-SST.
The 7B-SST cost for each mono amp the same $$$ new as the Stereo 4B-SST. (thus twice the price for a pair).
I would hazard a guess that the 7B-SST each chassis is really pretty much a 4B-SST designed to be one amp. (where the 4B-SST can be bridged, but ONLY for use into 8ohms.. the 7B-SSt CAN BE USED into 4ohms like the Maggies, as can the 14B-SST.)
This long goofy explaination is just to let you know why the 14B-SST (and the pair of 7B-SST) are TWICE the price of the $b-SST
