I am using a custom 3.1 speakers. Sounds crazy and it is. Im not sure how long it is going to last though. My right channel somehow broke so i soddered the right speaker into the left speaker wire, then i said heck with it, add another speaker, so i did, and threw it behind my monitor. It sounds great, clear at high volumes, just not sure how long its going to last. Maybe this is putting way to much resistence on the amp, who knows. But i am currently looking on line for new speakers. Also, would a 7.1 speakers work on my creative 5.1 live sound card? Would all the speakers work?
