Theoretically it is a sensitivity rating <img src="smile.gif" border="0"> 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 <img src="smile.gif" border="0">
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.
