[QUOTE="sundownz, post: 7116702, member: 549523"] From the prior link : "Excursion limit due to the magnetic limitations of the driver's motor. Xmag is defined as the displacement at which the BL product has fallen to 70% of its value at the cone's rest position." That is fairly standard in the industry -- it is how I rate our drivers. A driver can technically move WELL beyond x-max but BL related distortion will be pretty high beyond it. More linear x-max will help with low frequency extension -- especially in a sealed box -- but other specs will also have alot to do with it... but say you have two identical drivers spec wise one has 10mm x-max and one has 30mm... safe to say the one with 30mm has alot more maximum output at low frequencies.
