I have no doubt it would handle 5k of continuous, clean power, but the average person wouldn't be feeding it that much clean power. As a manufacturer, I'd probably rate it at 3k, just because there are going to be people clipping the hell out of their strapped audiopipe amps on these. //content.invisioncic.com/y282845/emoticons/hilarious.gif.02a037aad04aa96f19982b298a3d70a8.gif
Obviously, just my $.02. I'm not gonna sit here and say there's no way it'll handle that kind of power; just that the average person would probably blow it at that level. Although, if someone's putting together a system of this magnitude, I'd hope they'd know what they're doing, but we all know that isn't always the case.
