[QUOTE="THATpurpleKUSH, post: 8640622, member: 615398"] It's all about the sealed to ported ratio. The ratio, the volumes of each chamber and the port tune of the ported side create the shape of the pass band or the width and ripple of the response curve. The 4th order has a slow roll off like a sealed box. Cabin gain helps out big time as well. BBP does a decent job of predicting it and you can pick where the 12db/oct kicks in, I can't go back to Winisd because it's no where near close on anything below 50hz because it can't add cabin/room gain.
