[QUOTE="bladebarrier, post: 6207127, member: 603808"] At Fb your woofer is optimally damped, in a ported enclosure, so the woofer moves very little, it can take a crap load of power (mechanically), and the port does most of the work. As soon as you go below Fb however, your woofer starts to act as if it's in free air without any box at all. It begins to flop around and loses significant power handling capability. This is why sealed boxes are generally used for the absolute lowest frequencies. To be quite honest, there's not much real music below 30hz, so what are you trying to play that's creating an issue? 32Hz is probably a fine tuning for most music, to keep a mix of sound quality and spl.
