I scored some(100feet) individual 4ga. stranded silver plated copper in
thick Kapton from an aeronautics surplus house.
So, I silver soldered some
Cardas banana jacks at the ends after I put a pair in
techflexwith heat shrink on the ends to make it neat and pretty.
And am currently feeding the VR-1s with it.
The stuff might as well be hardline, but the room allowed it, so I went for it.
It milks every drop of bass from the VR-1's, but I still see a Sub in my future, if I keep them.
