bre2ts Posted April 17, 2011 Author Report Posted April 17, 2011 I realized I entered the dimensions wrong originally update Torres calculator pic. But even with updated dimensions it's still off. Quote Feedback 1 | Feedback 2 you win some, you lose some
dkahns51 Posted April 17, 2011 Report Posted April 17, 2011 I realized I entered the dimensions wrong originally update Torres calculator pic. But even with updated dimensions it's still off. The dowel displacement will be Pie (3.14)*Radius*Radius*Length of dowel/1728. now with that said.. im working on my config for these exact 2 subs as well.. im having a hell of a time...

dkahns51 Posted April 17, 2011 Report Posted April 17, 2011 Also i read the the Port area per foot is suspose to be around 15-18. That is what is screwing everything up for me... maybe external port?

bre2ts Posted April 17, 2011 Author Report Posted April 17, 2011 (edited) I havr been told for aeroports you can have less port area Edited April 17, 2011 by bre2ts Quote Feedback 1 | Feedback 2 you win some, you lose some
dkahns51 Posted April 17, 2011 Report Posted April 17, 2011 I havr been told for aeroports you can have less port area good stuff, where did you find those aero ports? And what do you think a good port per foot for those would be? Quote **Clicky>>My 2009 Subaru Impreza Outback Sport Buildlog<<Clicky** I'm messing up 98% of the time
