Hi there,
In a few months I hope to add a piece to my livingroom.
I'm thinking about laying tubes in my new concrete floor, so that speaker cables will be worked away nicely.
Does anyone hav advice what's best soundwise? PVC, copper, aluminum something else.

why would you think that running speaker wire inside tubes will cause a difference in sound? is this true? doesnt make sense to me....

Unless the tubes are made from something like mumetal, they won't affect the sound. They WILL affect the psyches of the terminally neurotic who are just as likely to tell you to orient the wires according to the principles of Feng Shui and that the tubes MUST be made of some weird, exotic material or you will RUIN the sound.
If you're not neurotic, run the wires through any nonmagnetic tube that meets local building codes and don't worry about it.

As long as the direction of the tubes matches the direction of
the wires, I think you'll be fine. 🙂
(NB, the above is just a joke and I make no claim about
the existence or non-existence of audible effects of tubed
speaker cables, nor do I mean to insult those who hear
such effects, whether real or imagined, nor ... well, you get
it, right?)

Re: DIRECTIONS PLEASE.
What? The joke? No, you must undestand it yourself. 🙂

Gosh, it'll be awfully hard to replace all those tubes when they go bad. Not to mention the poor heat disapation...
Sorry, I couldn't resist.

^^^ hahaha!!
Use PVC. Not magnetic, conductive or anything which could possibly have an effect on the sound. Cheap too.
Novel aproach to hiding wires BTW.

Re: GOING UNDER.
The cables are not shielded.
I was thinking the following.
Metal tubes might provide shielding, but also elevate the capacitance of the speakercable. Metal tubes cost a lot more than PVC tubes.
I've read that the choosen material the dielectric of cables influences the 'sound'. PVC is said to be not very good, teflon is good etc... I should read a book/article about it as I do not understand how the dielelectric influences the signal. Any suggestions?
Anyway I do not have a good understanding of the influnce to be expected, so I'm open to advice on this.
Cheers,
Andre

"tubes cost a lot more than PVC tubes."
I would be concerned about what material will comply best with concrete, how easy it will be to install and how much it will cost. Seems to me that PVC is the best material for this by far.
IMO all other concerns will be MUTE - ha! 🙂

This is not a joke :
most of the signal is traveling outside the conductor !
think of magnetic fields and electric fields made by the alternating current (=music) running through the cable.
This is why the insulator ( like PVC, Teflon or PTFE ) of the cable makes a difference.
So the surrounding material of the cable can influence the sound.
I was thinking of running my cables under the floor, supported in such a way that they are surrounded by as much air as possible.
I can recommend reading Allen Wright's cable Cookbook.

Hi,
As in Allen Wright's book, I would give the CAT 5 networking cable a try.
After all if you don't like it you can still hook up some PCs afterwards.😎
Several other Dutch audiophiles use that with excellent results.
If you want some links to their site I could look them up for you.
Just installing the PVC tubing should be OK here.
Cheers,😉

Ime Cat-5 does not contain enough copper, and ime I do not like the sound of Teflon insulation, despite it's good measured electrical properties.
I find 10 pair or 20 pair is much better for longer runs, and the pvc insulation sounds fine to me.
Also running the cable will affect/effect the sound, and standard pvc electrical conduit works fine.
Eric / - been using cheap 20 pair for years.

I suggest you use pvc tube because it is way easier to bend to the right position and you can have all kinds of joints and fittings if you need them. As for wire, my preference would be for 25 square mm welding cable. This is nice and flexible and reasonably priced and the conductor is about as thick as a pencil.
Welding Cable ?.
Graham,
Ime heavy Fig-8 cable like that is far too inductive, especially for a long run - that's why I reccomend 20-pair telephone wire.

Believe it or not...
CAT5 is actually very good cable , the insulation is not teflon though . Cat 5 is low capacitance , low inductance and the specs for it suggest guaranteed low insertion loss for long runs . It is after all intended for star distribution networks within office buildings (ie permannent wiring) for high speed local area network and telecoms (120 ohm balanced) systems . Cat 5E jumper wire (bonded twisted pair) is another type but usually a whole roll needs to be purchased . Other telecoms wiring systems such as the gel-filled types used by British telecom are also supposed to be very good , as are the basic 'twin and earth' 30A ring mains cables .
