So I bought some Presonus Eris E8s and they've been doing great for the few months I've owned them, but today when I was watching a movie on them the speaker on my right just died. There was no pops or snaps it just powered off and it won't turn back on. Is there anything I can do to fix it or should I just contact Guitar Center and see if the warranty will cover it?
There's not much you can personally troubleshoot. The problem is one of the following:

1) Loose wires between speakeres
2) right speaker defective
3) Left speaker amp not sending signal (so left speaker defective)

So unless it's an issue with the WIRE connecting both speakers there's nothing you can do other than pursue the Warranty.

Most Warranties are for one year on products like this.
