The back of my powered speaker gets really hot! Is that normal?

Yes! Our amplifiers are all analog "class A/B", which run at higher temperatures than other amp designs. Because of this, they sound SO MUCH better! The active speaker's rear panel may get hot to the touch, but it's certainly within safety agency standards. If it's truly overheating, (which is extraordinarily rare) you will likely notice a metallic smell. Then, the speakers will likely auto power off. If this happens, please contact customer support right away.
