[QUOTE="Loren Jones, post: 60037, member: 829"] Re: B&C Sub designs Kip, You are correct that you add the 200L net enclosure volume to the volume occupied by the vent. You also must add the 11 liters occupied by the driver itself as well as some volume for any bracing. Looking at your drawing, I am not sure why you still have 7" beside the driver. Is that just to get the proper enclosure volume? Or is that the vent? Your vent at 2.5" x 21" is what B&C recommends, but it might still limit the design in the end. It wouldn't make any sense to build new boxes because your old ones have port compression only to have the new box exhibit similar problems. If you have the space to spare I would think about an even larger vent. WinISD is a freeware product that allows you to model enclosures. It's not perfect but it may be worth using it to help you come up with a proper model for an even larger vent... [/QUOTE]
