I've got an 80 foot run to reach my sub (will be a HSU VTF 3). Are there any recommendations for what to run for the LFE? Should I use 75 ohm coax cable with audio ends? Does RG 6 vs. RG 59 matter for an application like this?


Thanks.

RG-59 or RG-6 will work fine. 59 is much more flexible, so I'd use that if the cable won't be in-wall.

Belden 1694 true 75 ohm would be perfect for the long length application you propose.

If you need more flexibility, you can consider Belden 1505F. Bluejeanscables makes them pretty cheap. 1694 is supposedly better, but not as flexible.

If I go the coax route, would I need to go with Belden or would Home Depot rg6 quad shield work fine? Keep in mind this is going to a sub.

Home Depot will be just fine.

I've heard elsewhere that shielded twisted pair is a better choice for subwoofer usage. Is there any truth to this?

I was always taught to use RG59 for subwoofer runs as well as baseband video applications. The reason for this is its construction. It is made with a solid copper core. RG6 is made with a steel core and copper coating. RG6 is made for higher freq transmissions such as satellite and digital cable. Since high freqs travel on the outside of the cable this is why. Low freqs travel on the inside so that is why you should use RG59.


Hope it helps!!

Not exactly right... You can get RG6 with a copper core, and RG59 with a steel core - it all depends on the design. RG6 is just a lower loss cable with a lower capacitance comparing to RG59, that's all.

In my new home, the low voltage contractor ran RG6 for the subwoofer, but he didn't terminate the ends. Any suggestions on how to get from unterminated RG6 to a RCA connector, including a wall plate?


How about an F-connector on the RG6 to a F-RCA adapter to RCA-through wall-plate? Or should I solder the RG6 directly to a wall-plate with RCA and solder tabs?

Will I be able to tell if the cable has copper vs. copper coated steel when I look at it in the store? Is there a particular shield thats better (braided vs. foil, etc.)?

1. It should say if it's copper or steel. If it doesn't, see if you can cut it and look at the cut - you should be able to see it clear.

2. For the sonic frequencies it doesn't really matter if it's braided or foil.

 

[shannonv]

So if shield type doesn't matter, does rg6 vs rg 59 matter?

For the audio frequencies I would say it does not matter.

 

[JCHanifan]

See, you learn something everyday. I thought the construction is what made the designation of the cable. Hmm. More research....

Well, I've got some RG6 on the way (you can see it here . It says it's copper covered steel, so I'm debating whether or not I should use it at all.


I was planning to make all of my short component video cable runs with it. Do you not recommend it?


Also, I have a 30 to 35 foot run from my receiver to my sub. What do you all recommend I do for that?


Thanks,
