[QUOTE="audioholic, post: 7599500, member: 549629"] How would cone speed increase db's? You will only increase cone speed one of two ways, by increasing the frequency so it has to move more times a second, or increase excursion so it has to move further each cycle. Traditionally DD has been successful in SPL by using a high BL design that helps improve excursion while burping at or very near enclosure tuning, where cone damping is at its maximum (thus requiring more force to reach full excursion potential). This has nothing to do with cone speed somehow increasing output. Mounting it horizontally, I agree. I thought you meant as in it would fail due to operating conditions. But even a better cast alum frame can break if it has an overly large motor, is mounted horizontally, and the motor is not supported inside the enclosure. Ive seen many 12-spoke frames broken from this. The difference between the stamped basket and a cast one is, the stamped basket would bend or warp, while the cast frame simply snaps in two. [/QUOTE]
