Grounded Speaker Cable

@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.

@rlb61 Wrote:

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

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.

It would be nice if this was on the website with an explanation of how it is supposed to work.
