before you go committing yourself, try having a close look at CAT5 core insulation and compare it to foamed insulation from an appropriate coax.

Then tell us an informed opinion.
Andrew, what exactly would I be looking for? Unless someone comes on and informs us they are a chemical engineer in the field of foam insulation and sets us straight, I don't think anyone can make an informed opinion. We are all just joking around and speculating.

If foamed, do you think the insulation on coax would be identical to Cat5? They're two entirely different products.

Bob, the only reference to time I see is Vp (the speed of light). So teflon operates at 70%+ and PVC at 50%. Other than that, you got me.

Google rules! search: FEP +insulation +foamed

At least for Belden, their Cat5 plenum uses an insulation called FEP. It's made by DuPont and is foamed.

There you go kind sirs, my informed opinion

Hi Lostcause,

8pairs upto 3m long and 12pairs for 3m to 6m long
you chose to ignore this recomendation. Do you have the desire to try again?

Taperwood,
thanks for finding the reference.

Already have done thanks Andrew and now I've managed to get it to about 4 metres.....by that recomendation (missed that one, sorry), I need to get another length in there as the 8 pair still has a lack of low base.
It's the sub 100hz that's lacking at the moment and it's choking the rest of the low/mid range.
If I play it at volume it actually sounds quite good but the neighbours (and the wife) would not agree

Cheers

Lee

Hi Lostcause,
your name appears to be at odds with your mentallity!

With these lengths I think you should really consider bi-wiring. Achieves delicacy (2/3/4pair) for the treble and oomph ( 12pair) for the bass. The extra work, cost and volume is quite acceptable in return for the performance benefit.

If you cannot get this to work for you, we would all appreciate confirmation, good or bad.

Hmmm I.M.O using the equal logic, 12' speaker cables are 2 pair star wound Cat5. This can be possibly over-kill, although I have at least performed SOME THING a lot more than simply a sole run involving Cat5. The particular high count Cat5e Wiring Services formulation produce not any good sense other than to jack this wire capacitance outside of picture.

Cat5 sucks a lot for audio (is an high-pass cable, due to its geometry).
Sat is mutch better (for both inside & outside speaker connection) in any sense, IMHO.
