6.1 audigy but i have a 4.1 system

[timmyqwest]

Actually i dont have either yet, but since the z560's and z680's are pretty much the same system except for the fact that one has a center channel + some more watts (i'm still not sure which one i'll get, obviously we know which one i want...).

My question is since the audigy 2 supports 6.1 can i just add either a front center (in the event that i go with the cheaper 4.1) or a rear center (in the event that i go with the 5.1's) or do i need a power supply for those speakers...i'm assuming i do in which case i wont be able to do either of these

If you ad another channel to the speaker system you will need to power it somehow. ie. and amp
