I really liked the cable I ended up using on my tower speakers. The cable is very heavy and flexible, I didn't even use grommets (something I usually do). I found out how durable was when I realized the tow rope was hooked on the corner of my Monster Tower where the wire came through AFTER I was boarding. The outer jacket of the wire did get slightly cut but the inside insulation was fine. This stuff is what I will be using on my next tower too. The sellers are pretty decent to work with too.
