I've had RTI A7s for about a year now, run by a Yamaha RX A810. I also recently added a CSI A6 and FXI A6 rears. The system was never very loud at all so I finally caved in and bought an Emotiva XPA 5. I hooked it all up, starting playing some music I'm familiar with, and noticed no difference in sound, either in terms of volume or sound quality. I turned it up a bit, and suddenly lost all power. Now the woofers put out no sound at all. The tweeters are seemingly fine(hard to know for sure since I'm used to hearing them with woofers) and the center and rears are fine.
Please tell me I'm an idiot and there's an easy fix for this. Like a fuse to change or something? I've never taken apart speakers before but I've taken apart other things so I can fix things if necessary.
It just seems so odd to me that all the woofers would go at exactly the same moment, in exactly the same way. Please help, I can't be without music like this!
