I have M60 v2's, QS8's, VP150 for my HT setup, and upstairs I'm using M2's and M3's.

I'm trying to figure out how sensitive they are. I look at the technical specs and there are two numbers - 93db and 89db - which is it?

I've seen people mention that Axiom's have a sensitivity of 93db, but in a review I just read it said they are 89db. Which number do *I* care about?

The reason I am wondering is more that just curiosity, since I ordered a Harman Kardon 7550HD and have been reading the manual in preparation for it arriving. In the manual it talks about setting your speaker sensitivities in relation to 88db or something like that. I came here and was hoping to just find the number(s) I needed in the tech specs but I'm just confused.
