Speaker Cable Too Short What to do?

In view of Perfectimage's suggestion, I would offer an idea that would work if you are trying to lay the cables around an inside corner of a room perimeter. Instead of putting an area rug over the cables, you can drill a neat hole in the floor at each end and run the cables under the floor. There are special caps professional installers use to cover such holes. Perhaps you could take advantage of a diagonal (rather than having to run two sides of a triangle) to save cable length. Good luck.

How big of a hole do you need to get the MIT box thingy through it?

The MIT circuit box is usually located fairly closely to one end of the cable and probably doesn't need to go through the hole.

Tim - thanks, a few of mine are good - most aren't but I do get a good idea once or twice a month...:-)
