Has anyone tried triaxial cable for speaker wires where you forget about the center conductor and use the two insulated braids for the + and - connections. The reason I am asking is in a active speaker system (separate amplifier for each driver) you want to minimize cross talk (coupling) between the cables for each of the drivers.

I've been using Sommer SC-Magellan coax speaker cable in the studio lately. It's a great sounding cable and easy to work with. Disclaimer : I use a lot of Sommer cable in my proaudio business, so I'm a bit biased.

This is more easily available so I will use it -

Again my major concern for 4-way stereo speakers is coupling between the cables for the drivers especially if I try to make the cabling neat by taping the cables together. Using coaxial cables should eliminate any coupling. Note that you can even have coupling in a cable with four twisted pairs such as Belden makes.

My comments only apply to active speaker systems where you have a separate cable feeding each driver. They do not apply to a system with a single cable feeding a passive crossover.
