A written description of the difference between internal and external biwiring can be very confusing. But to visualize, the external method just means that there are four separate wires going to four separate terminals on each speaker, and of course they come together as a pair at the amp end.
Internal bi-wire has the usual two wires going to each speaker, but with four leads at the speaker end for bi-wire hookup. The internal type is just used for the sake of better appearance, ie it eliminates two wires to each speaker.
But as Scott above notes, R. Vandersteen does not consider internal bi-wiring as beneficial as true (4 wires per speaker) external bi-wiring. If you really want to get confused, look up some of the archived posts on this subject. Good Luck. Craig
