[QUOTE="Papermaker85, post: 8573792, member: 572595"] that's a gross misconception. a dd 2510 has just about the same cone area as a SD x 12. efficiency is really tricky since the alignment has more more affect of efficiency. i'm not beating your balls but its much harder to equate than cone area. if anything its the alignment that the woofers are ideal in over efficiency. for example the sundown z4 is very low efficiency yet does great numbers between 30 and 45hz but for burps very high the don't come close to the higher efficiency woofers like say the DD 9500. so its really a matter in what hte drivers is designed to do the alignment you can utilize and the cabin gain. that's why i said a few weeks back you design the box around the cabin profile then choose a woofer that's ideal for the box.. if you would tuned up 10hz it would destroy your score and it would sound WEAK. if you switched to say 9518s you wouldn't like them nether.
