I've been having these speakers clutter up my desk for a long time and I finally decided to declutter my desktop and hiding the wires came as an added bonus. The benefit of this method is that it cost me $6.
Step 1: What You Need
---1/2" PVC electrical conduit (it's much cheaper than the drinking water kind---about $1.50 for 10 feet).
---A 1/2" type T fitting (a tee like you might get with plumbing pvc except it opens to allow pulling wires through)
---four 4m metric screws (the length will depend on the thickness of the next item needed)
---Something to mount the piping on (I had a used piece of 1/2" plywood that I didn't even have to cut!).
Tools: Screw drivers, a drill, a pencil, measuring tapes, something to cut your PVC, and a straight edge.
