702, again, yer explanation sheds no lite on why biwiring my speakers sounds better than not. perhaps having a separate wire for the *downhill* signal, & the *uphill* signal, as opposed to one wire for *both* signals, has something to do w/it. the tweeter network may reject the back emf, but if it doesn't have to, then it's one less ting for it to do when sending signal to the tweeter. again, i'm no scientist, but i *can* hear.
