Had to configure my system the same way due to room aesthetics, with equipment near one wall and speakers near the opposite wall. Ran speaker wires internally up one wall through the attic down the other wall. Must be around 10 meters because that is the length REL gives you for their powered sub woofer hookup. Used 10 or 12 gage for the B&W 805's. Ideal? No. Sounds great? Yes. Should work out.
Run length
Room layout dictates the sub is on the opposite wall. Not ready to run a wire across the floor. It would be 26 feet.
To skip the floor run I would have to go up and down inside the wall. That would add another 18 feet for a total of 44 feet. Too long? Will be using plain old 14AWG cord.
