Speaker wire beside light runs
#1
It was inevitable!!!! :-(
The electrician installed some ceiling speaker conduit beside the ceiling light (220V) conduit. So now I have 2 separate flexible pvc conduit pipes running side by side.
Am I screwed? Will I hear a buzz in the speakers? What are the chances of trouble?
I didn´t decide on the speaker cable yet. By getting bigger/better speaker cable am I reducing the odds of trouble?

Thanks in advance.

You could always use a shielded speaker wire. No gaurantees but it might make a bad situation better or eliminate a problem all together.

I'm sure it costs more but might be worth it.

I never even knew shielded speaker wire existed. Is this standard stuff that Belkin or Monster would have, or is this specialist wire? Great tip. I agree that it may be better insurance at this stage.

A quick google search found this.

And this article about speaker wire in general. Specifically the last paragraph which says -

Quote:Speaker cable can also be shielded against line noise and interference. Belden makes a twisted-pair wire, model #8718 that can be used quite well as a speaker cable. The Model 8718 is 12-AWG twisted pair wire, with a foil shield and drain wire for an easy connection to earth ground. If you have a question about earth ground, take a look at the electrical cable article for information on the concept.

Markertek's page for the Belden #8717.

And finally what looks like a good article on this subject from Audioholics, "Bulletproofing Your System from Interference".

This is really helpful. Thank you for digging this up.
The more I read, the more I think I should not accept this and should get the electrician to run totally separated conduit for the speakers - like in the original plan! Undecided I still have a few weeks before things are sealed up forever.

Thanks again.

Wow - at a buck a foot, I think I'd also get the electrician to rerun the conduit. Nice wire, but certainly not cheap.

I agree but it's an option! I wasn't sure if the walls were closed. Also, if they were closed, I'd probably pull the basic wire and change those (or have the electrician change them) which are a problem rather than run the expensive stuff everywhere.

Either way it's not ideal and it's an option in a pinch.
