To be fair, that price is for the 12 meter (40 ft) cable. The 75cm (2 ft) cable is much more affordable at just £600.
The best part about that cable is that someone took the time to determine which direction it sounds best, and the cable is marked to make it straightforward to attach it in the best direction!
I doubt it. That seems like the sort of thing that could be illegal. Getting an intern to listen to the cable in both directions and mark an arrow on would cost what, $.50/cable?
