    Default Question on 12B wiring

    I rewired one of my two RTA 12B's last night. I was looking again at the wiring diagram, and in the original schematic, the white wire goes to the negative side of the the two Mid-bass drivers, but then it goes to the positive side of the tweeter. Would this not make the tweeter out of phase with the other drivers?

    I am looking at the diagram labeled schematic_rta12b-rev.pdf available on this website. Is there a possibility the labels on the diagram are wrong? Or is the tweeter in fact out of phase with the other drivers?

    This came up a while back. IIRC the tweeter is wired out of phase - the schematic is correct. I'll try to remember to double check when I get home tonight.
