I have recieved my 2214H's and they have the spade lugs for connectors as opposed to the colored push buttons I'm so used to. On the other speakers I looked at incl. the L-110 LE5's and the tweets on the L-150, it looks like the male spade is the negative post, but with all this talk of negative vs. positive polarity, I'm not sure. Just which speaker spade is the negative on the 2214? The male or the female?
