[QUOTE="Kip Conner, post: 60039, member: 445"] Re: B&C Sub designs It looks big to me but let me show you how i got that 7" opening... 339 sq cm is equal to 133.465 sq in. One side of the opening is 21" so I did the division 133.465" / 21"= 6.35" Giving me a port area of 21" by 6.35" Is this right? All the freeware in the world is for PC... :( [/QUOTE]
