What's the power handling on the super 3 xrs and similar speakers? I'm lucky enough to just have gotten a pair used, and I'm used to planar speakers which, almost literally have no limit to how loud they can go except for what your amp is capable of. So sitting here with my super 3 xrs and a 50wpc ss amp, obviously they're really "tearing shit up" with the volume knob only up to 9 oclock, but darn the drivers are so tiny, any higher and I feel like they're going to explode.. but I still want them louder!
