I'm not sure what I'll be using for speaker cabling when I get my system done, but for the internal wiring within the speakers I splashed out and used litz. Only because I was able to get the stuff mega cheap - where I worked we used the stuff by the kilometre and also had the odd engineering-sample roll lying around. If it's good enough for multi-kilowatt power transformers running at hundreds of kHz, it'll be good enough for audio. The downside of using litz is that it's a real pain to connect, as each strand is individually insulated (hundreds of them, hair-thin) so you can't just bunch the end into a binding post. You have to thoroughly tin the ends using a high-temperature soldering iron then solder it to a connector. To connect the amplifiers to the bass drivers I'll probably just use big fat generic cable but I think I have a couple of metres of litz left over so I might use that for the mids & tweeters, or maybe cat5 if I don't have enough litz. The mid & tweeter see very little power so they don't need a heavy-gauge wire. I will be glad to get those pesky passive crossovers out of the way (see pics at the bottom of this page: all I've changed in the past two years are some resistor values to tweak the padding): http://www.digistar.com/~dmann/speaker2/ - Dave -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
