Alan, could you please settle something for me?

I'd understood that the QS series had the tweeters wired out of phase, but the woofers wired in phase. All of your recent posts (and Newsletter articles) state the tweeters are also wired as bipoles.

Are the tweeters wired as bipolar or dipolar, and is this something which has changed since the switch to the SE designation (along with, for example, the TWWWT array on the VP150)?
