Hook-up Wire: Duelund DCA16GA vs Neotech STDCT-16 vs Cardas 15.5 AWG

Hi @lemonhaze, thanks very much for your helpful answers, and sorry fow my late reply. I've ordered some parts, and will report back with the results when I have installed them. 

In the meantime, regarding point 4: it did not occur to me that I could solder the big coil directly to the speaker terminal, especially to the mid-bass driver. Is there any specific reason for not putting it in the external XO box, but nearby the voice coil of the driver? 

In answer to your question, I've got some Jantzen Superior Z-Cap and Kiwame 5W resistors at home to start with (plus Jantzen and Mundorf MOX resistors). Later on, I'd like to try Powertron metal foil resistors as well. 

Since originally, this is a thread about hook-up wires, I'll report back especially on the cables as well. I didn't want to steer away from the topic, but this was the pllace where I could find the most helpful answers to many of my questions. Should I start a new thread?

Duelund 600V DCA12GA, DCA16GA, or DCA12GA on the "Stokowski" Altec's as speaker cables? Update! - Jeff's Place (positive-feedback.com)

i m now using the 12g 600v for speaker wire with great results.

The Duelund is colored with the oiled cotton 

and micro  arching between strands ,the Cardas sounded noticeably cleaner 

especially low level detail , even vs Neotech ,but getting the enamel off the strands a pain in the ass at first , you need a hot iron ,or stainless brush first on dremmel 

then clean, flux then good Cardas solder to tin nicely and this wire in the 15.5 gauge took 2-250 hours to fully settle in ,remember a speaker is only pulling 30-40 volts tops if that , I felt that was a good average size gauge l
