[QUOTE="winkychevelle, post: 8729935, member: 611804"] I don't believe next to any American bass subs perform well sealed. They typically use stiff suspension and rely on ported enclosures to perform to peak efficiency Idk how you figure that. 2 dd1506 is 66in² of cone area with 10mm of xmax 132in² if you call the rear wave essentially a second set of woofers. This moves 52in³ of air combining the front and rear wave 2 sd4 8s is 100in² with 14.5mm of xmax, the moves 57in³ of air Honestly I don't see moving 5in³ more in the case of the 8s to be truly impactful. Though it does show the advantage of using the rear wave in a ported enclosure. [/QUOTE]
