alright so I just got a replcement mid for my SDA and i'm not sure if the new speaker is in phase. The wire coloring is non standard (a blue and a white wire) and there is no demarcation on the old speaker as to what end was positive and what was negative other than a red dab of paint on the magnet (which i've assumed was positive). Anyone know if the red dot is a demarcation of positive, or which of the two wires (blue and white) is positive? Also, i've never been able to identify which particular SDAs these are. they have two tweeters spaced horiozontally next to each other on the top, then two rows of two woofers below that. any ideas?
