My sub died a year ago and I never got it repaired due to reading threads on here where people had the same problem soon after having it repaired. It's the sub amp that's fried. I wouldn't want to purchase another sub, unless someone fixed the amp problem themselves, because I am afraid it would die again. I really liked those speakers. They sounded great. I'm getting a new desktop to replace my old dead one and need some new 5.1 speakers. I wish there was a different sub I could et that would work with the speakers.
