IS it the shop in teh Mongkok basement???
He sold me one sub-woofer cable as well 3m for $3XX
Since this is my first SUb woofer cable, I am not sure if it is good or not!!
But it seems not too many ching talk about it..so be on the safe side, unless you have a chance to test it, otherwise I would suggest you better try some other brands mentioned by other chings..
Please, I am not saying Voltom is bad, I just saying I do not have any chance to compare it with others...
