    The cables are basically the same, just a phono plug on each end of the cable.

    The difference is probably the quality of the cable used & the connectors. As you may know, the 3 phono lead you get with most AV equipment does the job, and it doesn't matter if you plug the yellow video lead between the right or left audio, you still get a signal.

    That's a thicko's guide, as that is about my level, but I'm sure there is a more techie person out there who can eloborate further....

    Some manufactures say that the sub cable are built to handles low frequencies better ( better noise rejection and higher bass response). . . don´t know if this is entirely true but the sub and RCA cables have somewhat similar prices so i believe its worth the extra 4£ :)

    Thanks -it's just that I have a spare good quality digital coax that I could use to save me spending £20 on a sub cable

    The answer is acutally no: a sub cable has an impedance of 50 Ohm (like normal interconnects) while a digital coax has an impedance of 75 Ohm.
    However if using a dig coax as subwoofer cable makes an audible difference might be debatable.
