ALPINE408 Posted January 5, 2012 Report Posted January 5, 2012 it looks like the were the port ends in the box will just be 3 inches of the back wall you want that to be just as far off the back wall as wide as your port is whats the point of havint 5.5 inches of port opening if its choked by 3 inches of opening off the back wall Quote Have you ever had your woofers blown?
stanbro Posted January 5, 2012 Author Report Posted January 5, 2012 Why would these numbers not match?? Sub placement is not in the equation and the area is the same...

stanbro Posted January 5, 2012 Author Report Posted January 5, 2012 (edited) i lose one inch in the port entrance.. because i want consistent surface below subs.. not a fair trade?? ..unless your saying the 45 will eat another 1 1/2"?? it looks like the were the port ends in the box will just be 3 inches of the back wall you want that to be just as far off the back wall as wide as your port is whats the point of havint 5.5 inches of port opening if its choked by 3 inches of opening off the back wall Edited January 5, 2012 by stanbro Quote Build v1 15" Skar VVX (custom ported box) w/1.2k Sundown ampBuild v2 18" DC XL x2 (custom ported box) w/4.5k Skar amp Build v3.3 destruction and re-construction time!
ALPINE408 Posted January 5, 2012 Report Posted January 5, 2012 you want the same distance from every wall as the port opening or more if you have a 5 inch port opening and its 3 inches off the back wall you might as well just have a 3 inch port opening Quote Have you ever had your woofers blown?
