Thanks Red_or_Dead and Splave, but I dunno Red.. add some cellophane and you got yourself some case mods!!

and where did you find a pic of me on the net Splave, identity theft lol
But on a more serious note, I'm thinking of adding this sub to my computer system which is evolving. Sound-wise I have a set of logitech z5500's but how to add the extra sub into the system.... I've been reading some forums and seems the best way is by adding a receiver into the mix. Sorta needing a reciever with optical in and out with sub out
Mac Pro ----> Reciever ---> z5500
---> companion cube
(via optical cable except reciever to sub)
Any thoughts....?
