I have a Carver True Subwoofer and was told recently that you should use coax for carrying the signal to powered subwoofers. Admittedly, I had been using standard speaker wire onit, just the same as the rest of my speakers. With the recent changes in my setup, I have an opportunity to correct this.

Fortunately for me I have three coax home runs already in the room. So if coax helps insulate and preserve the audio signal what connectors do you use? The sub accepts RCA-phono style plugs. Do they have an RCA style plug thats compatible with coax cable or?

I use a sub cable (rca style), personally. I've never seen a sub that accepts coax, much less heard of anyone actually doing that. Then again, I'm new to this shit.

The make a adaptor the screws into the coax fitting and turns it into a male RCA port. I use them myself and they work great.

Cool - so what do I stand to gain by using coax over standard speaker cabling? Cleaner signal? Less signal loss? Will I be able to "hear" a difference?

I guess this is something like I am after for the living room

Alot of subs out there have inputs for coax. It is far cheaper to run a 50' piece of coax over a 50' piece of mini rgb or rca type cable. Although I have both in the garage should you need some. Only thing I can see different is that most rca cables(lower end ones at least) are stranded while coax is a solid conductor.

Here's another style non 90 degree....

I think the person you were talking to most likely was referring to a digital coax cable.

It looks like an RCA cable but it has a different resistance.

I'm not familiar with your sub so I couldn't say what your connections look like.

yes, but isnt RG6/75ohm coax the same stuff they use for cable and satellite connections? These type cables are stiff with a solid core conductor and just dont seem right for speaker connection but maybe I'm wrong?

You could also put RCA ends on the coax so you dont have to use adaptors.

for subwoofer, solid core cables are fine since you are just sending 80Hz (or around there) and below.

stranded copper is better for high frequency.

I use a Dayton RCA subwoofer interconnect cable. http://www.parts-express.com/pe/showdetl.cfm?Partnumber=181-642
