Wife stepping on speaker wire

A small decorative bridge might work well

Place your cables off the floor with fluorescent colored paper cups and for added benefit place x-mas wire down on the floor.

Use duct tape (preferably brightly colored) to tape the cables to the floor. Serves two purposes ... protects the cable, and makes it much easier to see, all in one !
That's what we used to do with guitar and mic cables when we were gigging and it works a treat. Hardwood, tile, carpet, duct tape does it all.

Is there some sort of spray you can get to spray the floor around your cables to keep your wife away ? "Wife repellant". (perhaps beer would do it).

I thought it obvious that my comments, like those of many others, were made completely in jest. I wonder if I'm the only one who got four ... yes, FOUR ... nasty emails from Mrs. Hughes ... LOL. Personally, I'm betting she steps on more than just speaker cables (oooh, boy, now I'm gonna get more hate grams from Mrs. Hughes ... LOL).

Hey lady ... lighten up.

As a women who's father is into audio and now who's husband is into audio I find that finding ways to include the cables into my decor is a challenge but one that keeps me on my toes litterly.
