Grounded Speaker Cable

Makes me wonder whether the separate ground wire could cause a ground loop hum due to too many grounded items. 

@ditusa These speaker cables apparently have a ground wire running from the cable itself to a nearby outlet. If the purpose of this is to reduce RF (as with Tannoy), then it may be more useful in a city, where a lot of RF exists typically, instead of in a more rural area.

The separate ground wire is not connected to the crossover.

I think it earth grounds the metal driver speaker basket only. In my opinion, it's for marketing purposes. 😎

@rlb61 I think your best solution would be to email or phone Captain and inquire, that way you get an answer directly from the source. I believe if Captain designs it there is a purpose.

I spoke with Cap. Still not clear on the need for a ground wire on the speaker cable of my amp is grounded already.
