Speaker with most dynamic PUNCH?

What speaker have you heard with the most dynamic PUNCH? I am looking for a 2-way design to be more specific.

I had some Infinity Beta 10. It has a 125 wpc power rating. Sure this is hardly a high-end speaker but still, I was struck by how lifeless the sound was compared to my Seas Excel driver. I attribute this to lower quality magnets and cost cutting design.
