Getting the thread back on line...I have a question...

The article that Peter linked to includes a chart that talks about a 50 foot run for 16 gauge speakers wire. Does this mean that the wire run should only be 25 feet out to a speaker, and than 25 feet back to equal 50 feet? Or, can the run be 50 feet out and 50 feet back?

Also, does anyone have an opinion about "flat" cable that can be run under carpets opposed to regualr round cable?
