Currenly I'm running Monster
XPHP-CI100 12 Gauge speaker wire to all my speakers including the (2) towers - 30ft (total) , (1) Vertical Array center 15ft (total), and (4) bookshelf speakers - two runs of 30ft and two runs of 22ft. I terminated the ends of the lines at both ends with Monster self-crimping banana
connectors QL GMT-H which work wonderfully I might add. For my subwoofer I am running a Monster Cable
MB400 18 ft. mono cable.
