I never used this driver but I did simulate it lately to check how it performed against my Oberton 10B200's.
Since the tsp's of the Beyma are almost the same as the Oberton they perform pretty much the same in a 30 (to 35) liter enclosure tuned to 43 to 50hz.
The Beyma has a mathematical based xmax of 7.5mm, doing the same trick gives the Oberton's an xmax of 6mm. The max spl in the bass region is pretty much the same for both drivers (+2dB for the Beyma). The Beyma can get like 4dB louder in the mids because there the power handling is what counts.
If you live in europe you can also try the Oberton's, they are cheaper then the beyma's and they also don't have that nasty midrange peak.
The pictures shows the simulated responses and the max spl(rms) responses of the 10b200 (blue), 10mwnd (green) and deltalite 2510 (red) in a 30liter enclosure tuned to 45hz.
The 10mwnd is the winner here. The deltalite has a powerdip(hitting the xmax), this powerdip even increases when the max spl is simulated with the peak power. The beyma and oberton can both almost take the peak power before this starts to happen.
