Wife stepping on speaker wire

Put up a sign that reads,

***************Caution***************
These cables emit a small amount of radiation.
Any contact may cause thighs and butt to swell.

Look for a good divorce attorney.

Buy her some very high heels and usually one good ankle twist does the trick.....would have been a great gift today. Try flat cables or put a throw rug over them. PT

I would not ever leave any cables in contact with floors, I would suggest relocating the speakers so you can keep the speaker wire off the floor.

Be a man about (even at the risk of a marital dispute) and tell her how much those wires she's stepping on cost. Or, you could just raise the wires a few inches off the floor, with either home made supports or any of a number of commercially made cable supports as many dealers and cable makers advise us audiophiliacs to do.
