Well I am getting a high end system wired into my new house that we will start construction on in the next 60 days. The AV consultant I have hired is using 75ohm Coax wiring for ALL speaker wiring.
In this case, the consultant is handling the ENTIRE wiring end to end, working with the builder to get everything right.
hehe. Leave it to the professionals m8. No way he is using *75* ohm coax wiring for *8* ohm speakers ;) The 75 ohm stuff will be for the Cable TV, and it had better be quad shielded RG6 for inwall runs.
Actually the 75 ohm stuff is for things like component video and subwoofers. The 7.x part, ignoring the subwoofers is shielded twisted pairs. Having a 75ohm connection to the subwoofer makes sense as it is a low voltage signal like the baseband audio from VCRs, cable boxes and the like. All those cables, at least the better ones are 75ohm coax cables for reduced interference. Shielding is quite common in cables that cost $20 or mroe each for 6 foot pairs.
