What is the xmax of this driver? One way, not peak to peak or mechanical limit?

Not exactly sure of the true xmax by way of BL@70%. This sub can move at least 2.5 inches (54mm). I have used this sub at full excursion and haven't notice any major distortion during its peak excursion. I will do more research on this sub in later videos, find me on youtube @ Subdynoman

This speaker blew After standard break in with 1,000 watts on dyno. ....... why you think it’s sooooo cheap?

If you believe 8000 watt Max is the power you can put to it before it blows . You shouldn't have a big system . So if you're rich and just decide to buy something big for a first system you've ever had .start out small and do some studying on ohm's law an electrical current and a little bit of physics . And then you'll understand. but if you had two of them and wire them down to a half an ohm they will blow with enough watts . I have melted speaker wire before ! 12 gauge speaker wire
