Tvor-ceasar has absolutly right its the xtz cables they are not super fancy but the build quality is very nice.
I campared it to the svs soundpath speaker cables witch has very nice build quality but they are alot more expensive here due to import taxes.
Maybe the svs cables is cheaper to buy in US cause i think they are made in ohio.
Will post some more pictures later on when i finished my speakerstand for them and ofcourse im planing on building one of your subwoofers.
