so to start i have never built a box always have paid somebody else to do it but truth be told i'm never happy with the out come.
im not here to blast anyone nor start an argument simply trying to understand the basics .
1st on my list is how to figure out tune , i have heard some tune gross box and some tune off the net .
for example i have a box that is 48w x 24 tall x 25.5 deep .75 wood single baffle all around 1.75 total displacement 3 common walls subs up port towards trunk total port area is 45 "l x 4.5 tall x20" deep . box builder swears its tuned to 34-35 when i punch in the program i get 40-41hz .
2nd question is how does amount of port affect area effect subs ? i have heard people use a lot of port vs some use little .
im after a daily build that can play across the board and do a decent number as well but main goal is to play music. i don't mind trial and error simply trying to understand how it all works .
