Sensitivity? Or maximum output? Those measurements are useless unless you are comparing to other subwoofers measured BY THE SAME PERSON in THE SAME SETUP. Otherwise, everyone measures in different spaces using different equipment, sometimes smoothing, and sometimes they add "room gain" or other nonsense
--> You simply cannot
compare such specifications from different companies.
Sorry, but true, that has been my experience as a loudspeaker engineer visiting many different factories etc. Now, if you can find the sub in a database all made by the same person with the same equipment in the same measuring space, only then can you make any comparison. I don't see such with your model in it
ing said, why do you ask about this? What are you trying to do? Replace the subwoofer with similar?
My take on the JBL measurement is they have a very solid 400 "real" watts amp inside.
