What does this all mean? The 15" below will handle a lot more power and I would assume can be EQed to do even lower. Would that be where it can get much lower than the specs for the cabinets say?
15" Legend CB15
5.3 ft3 -> F3 of 47 Hz
2.75 ft3 -> F3 of 61 Hz
10" Legend B102
2.8 ft3 -> F3 of 44 Hz
1.7 ft3 -> F3 of 54 Hz
The CB15 is a good general all-around 15" bass guitar speaker. The B102 is unusual for a 10" in that it's optimzed to go quite deep, but it trades off efficiency and top-end extension to do so.
The CB15 is about 6 dB more efficient than the B102, so that's why the CB15 needs more internal volume even though it doesn't go as deep.
Both can be very good choices depending on what you're trying to accomplish.
