Message: <blockquote data-quote="audioholic" data-source="post: 655048" data-attributes="member: 549629">xmax is actually rated as the lesser of xsus and xmech. This means xmax is limited either by motor force, or by suspension limits. Some subs will hit their suspension limits before their motor limit (called suspension limited and is fairly common), thus you wouldn't want the rated xmax to be greater than the suspension could actually move, or further than the suspension can control the cone in a linear manner that still keeps it within the acceptable distortion levels.. This is why xmax (usually) is the lesser of xmech and xsus, mechanical limits definitely do play a role in xmax.xmax is rated for linear travel, which I believe is defined as 70% BL distortion.</blockquote>
