Don't get me wrong, I am not dought what you say, I was interested to see
if the solution that these companies who sell structured cabling systems
provide, is really any good. At the last Build it show I went to, one firm
was saying that you could "pump" sound through out the house with
cat 5,
and that wasn't using KAT5.

Changing the subject slightly, what is the best and most cost effective way
to split the output from an amp to all these separate speakers. I see that
QED  do a speaker switch with independence balancing for about ?100. Is
there a similar box that can be controlled remotely ?

Hi Graham,

I saw that site too but cant remember the link.

2.5mm cable or 79/0.2 if you prefer that notation is rated at 18A which
will
handle in excess of 1200W into 4ohms. To get that kind of current handling
using CAT5 would need 72 strands for each wire. Thats 144 strands in total
or 18 runs of CAT5.

79/0.2 is ?39.99 per 100m from Maplin so that is 40p per metre
CAT5 is around ?35 per 305 metres so 11 p per metre X 18 runs = ?1.98 per
metre.

Hey !!! They are correct.... a one inch diameter bundle of CAT5 is cheaper
than speaker cable costing over a tenner a metre... but I think I will
stick
to under 40 pence per metre for my high current speaker cable measuring in
at just 3mm x 6mm.

I wonder how many runs of CAT5 I would need to replace the cable from my
car
battery to the starter motor. NAH!! Wouldnt work, I would have to take the
engine out to leave room for the bundle of cables  :-)
