Each positive and negative polarity/leg is separately constructed using 10 individually insulated runs of 16 AWG stranded wire, totalling 6 AWG for each, then covered in a layer of Vibration Reduction Sleeve before adding the finishing sleeve(s).
These cables are neutral, provide excellent bass extension and tightness, and throw a wide and deep soundstage with blacker backgrounds. They are also quite light and flexible, making them very easy to maneuver despite their size.
The standard configuration of all models is an 8' pair terminated with Straight Banana Plugs, but there are additional options listed with each model, and they can also be purchased individually (ex. For a centre channel speaker).
However, if the listed options don't meet your needs, feel free to get in touch; if you can dream it, I can probably build it.
P.S. Speaker cables use roughly 4 times the materials, and take 3-4 times longer to make than power cables do.
For those reasons, there is usually a considerable price jump for speaker cables with other cable makers.
I realize this will sound like a cheesy sales pitch, but in an effort to keep their final price(s) in line with my power cables, I have (heavily) discounted the labour on my speaker cables. There's no need to thank me, just buy a set and we'll call it even.
