Hi Peter,I notice you ain't had any luck with replies ... so I thought I'd give you my A$.02 worth!! :-)) (Not that I'm an Orion expert ... but I do know AKSAs! :-)) )
By all means use magnet wire (or Vampire's cc/ccc equivalent) but for tweeters - because of the high frequencies - I would use 24g, max. But, yes, use multiple strands to bring the combined guage up to 17g. But I don't see the point in putting each strand of magnet wire inside a teflon tube ... the Vampire wire is already insulated with some stuff ... polyurethane or something!
BTW, when you said 4 strands ... I'm assuming you meant 2 strands for 'hot' and 2 for 'return'??
IMO, it's very important to ensure individual strands do not move relative to each other ... so a loose 4-wire braid would be the best of your alternatives. If you take up my suggestion of 24g for each wire then obviously you need more overall strands so I would twist 2 wires together and then loosely braid four twisted pairs to give you your overall cable.
Another alternative - very easy to make up! - would be to buy Belden 1585lc which (if I've remembered the part no. correctly) is plenum-rated Cat5 cable with solid-core, 24g strands, teflon insulation around each strand and an overall teflon jacket. For lowest L (but highest C - which for that short length shouldn't be a problem for an AKSA) you would use the 4 solid-colour wires for 'hot' and the 4 striped wires for 'return' ... and they're already twisted inside the jacket!! :-))

Andy
