The Ermagerd isn't designed to be a competition sub, it can be used as one, but it's mostly used as a daily driver. & Yes the YOLO is the competition sub, Your right. But if you took a all out spl sub & played music through it I'm sure it wouldn't sound as good as a musical sub would. Like how people do comps with the Ermagerd , it's a daily driver not a SPL Sub , then they go talking bad about it when it doesn't perform Like A SPL Sub would. Even though from what I heard, Tony economou did a 150 with a single 18" Ermagerd on an ns1 @ .5 ohm.
