RG 59U For Speaker Runs


We are starting to run silver core RG59U for our speakers, and it is working very well, just wondering how this has been working for other. Or it could be we are just slower with the new stuff in UT

Re: RG 59U For Speaker Runs


RG59 as in coaxial? Typically RG59 has a 20 gauge core. Why would you run 20g wire for speakers? How do you terminate this?

I've used RG-6 with Snap-n-Seal's RCA ends for subs, but not for the regular speakers. Sounds silly.

Re: RG 59U For Speaker Runs


I've seen coax "bundled" in a "jacket" with speaker/power wire but it would seem odd to use caox itself for speaker wire, would there be some problems with that? Wouldn't there be an impedance matching problem if the cable wasn't specifically for speakers (I don't know)?

Exactly. I use RG6 for subs too, but no way no how would you use it for a speaker.

When i do my home theatres it is in 12 gauge stranded or 10 gauge stranded.

Re: RG 59U For Speaker Runs


When speaking of Speakers and Nominal Impedance and Impedance Curves, Gauge versus length is the ONLY real factor. RG6U is good for up to 32 Feet with 8 Ohm load speakers and 16 feet for 4 Ohm speakers. It does not make a difference in the wire construction of copper. Solid, stranded, braided, oxygen free, etc. What matters is that it is copper and the correct gauge for length.

Over-gauged wire is a waste of money unless one considers the possibility of a future change in speaker configuration as in todays 8 Ohm installation and tomorrows upgrade to 4 Ohm speakers!

If you can purchase Coaxial RG6 or RG11 cheaper than 2 conductor stranded, then by all means use it!

The only not-so-upside is the aluminum resistance compared to the copper resistance. Should not be a factor if wired properly. Unless you have coax with copper shielding then it is NOT a factor at all.

Um, what sized room is this? That's a little extreme for most cases unless you are doing a bunch of 1000W speakers with a power amp the size of a VW Bus.

Well okay, in that case I would use even thicker than that.. but still, 10g for speaker wire is a lot of wasted copper.

Re: RG 59U For Speaker Runs


I guess for very small runs, if someone was so inclined, they could muck about with RG6 for a speaker wire. But why would you...
Basic 2 cond zip cord is cheap, and really easy to strip and connect to the speakers.
The OP doesn't state if they were just running short amounts from a stereo to speakers, or trying to pre wire a whole house music system this way.
There is one company I have used that offers speaker wire over RG6. I believe it's called MIT one wire, BUT, they have expensive connector / adapters that they require you to use, not making it an inexpensive solution.

Re: RG 59U For Speaker Runs


The speakers were 1000w's. I did 4 rooms in a basement with 10ga stranded. It sounds amazing and was not to hard to wire. It really was not that pricey might have been 20 bucks more then 14ga stranded. We have a good electrical supply house that we have been getting our wire and parts from for some time.

Sorry to change the topic, but Homes, where did you get my name from??
I looked at your profile, no name, looked at my profile, no name. Just curious.

Re: RG 59U For Speaker Runs


Usually the manufacturer of component knows the best way to connect their component. Subs and A/V rcvrs have coaxial outs/ins and don't require you to convert with an adapter. Speakers have binding posts or those spring-loaded thingies, as do the A/V rcvrs. Stick with that. Only time I use RG-59 is with security cameras.

Re: RG 59U For Speaker Runs


Seriously, from experience:
We have used RG6 & RG59 for hi level audio - not by choice, it was a fix for another company that pre-wired a home and indicated that they ran speaker wire to locations that they did not and when the home was finished they were left with this issue.

Do not do, people told us that it cant be done, but we figured it out and it works fine. not great. there is definitely a noticeable difference in audio quality. we hot dropped 16 awg to see and it is amazing how noticeable the diff is.

however, with that said, if it is necessary, it can be done.

Re: RG 59U For Speaker Runs


i do have a feeling though, the poster must be talking about low-level for rca connections to active speakers.

Re: RG 59U For Speaker Runs


He does mention Speakers (plural), to many that would not say subwoofers or other active style speakers.
Mind you the OP hasn't responded either, thus the post is hard to take seriously.
Using RG59 or RG6 for an active speaker will work, but you still can experience problems.

If you use it for speaker level, its going to turn into a hi-pass filter and shave off your low end
