Linear BL will matter to, you'll only pressurize air while the woofer is pushing forward with constant force, the millisecond BL begins to deviate your displacement is irrelevant. A sub with linear BL for 12mm will produce as much pressure as one moving substantially more but beyond xmax. The idea is Sd x Xmax is displacement of course but alot of people like rating things improperly. Overhang method is the only way to be accurate, 70% BL is not a good way of measuring.</p></blockquote><p></p>
