Theoretically it is a sensitivity rating

It is supposed to be a measurement taken with a mic set 1 meter from the speaker. And the speaker would get one watt power. However like most marketing crap these numbers are not always reliable

Once again theoreticaly the higher the number. The more sensitive the speaker. What translates to in english is. The higher the number the less power the sub needs to get loud basically. There is alot more involved but this is the general idea behind it.

I don't really understand what you mean by "bass sensitivity".

It means the higher the number the more efficient the sub is.
