[QUOTE="Robert Kasleder, post: 208640, member: 12075"] Yes that's exactly what I was looking for, since I will only operate the speaker up to 800Hz maximum. But the low end is important, and Xmax plays a big role in that. I don't know if the Xmax values of the 18Sound speakers are truly matemathical or no since they don't give you the magnetic gap height and the winding depth. And I don't know if in reality i get that SPL advantage from the NMB420 over the 8NDL51 Here is an Xmax sym: Yellow- 18Sound NMB420 Xmax 5.8 - excursion: 6.3 at 100hz at 1000w Green- B&C 8NDL51 Xmax 4.5 -excursion 5.3 at 100hz at 1000w Red- 18Sound NW650 Xmax 5.5 - excursion 6 at 100hz at 1600w So at the and the my question is if the 18Sound 8NMB420 is worth the extra 40Euro/ piece over the B&C.
