jmilch Posted July 26, 2011 Author Report Share Posted July 26, 2011 Ok guys so I used both torres box calc and the calc from precision sound (found here) and I decided to just go with aeroports. But I am trying to figure out how many I need. If I do 2 x 4" ports by a 25" length, I can tune to 32 hz. Does this sound like its in the ballpark? OR If I do a slot port, I came up with 3" x 9" x 29" That gets me 13"^2 per foot, and 31.5 hz tuning. Does that sound about right? Either one of those will work fine Thanks.

Does this sound like its in the ballpark? when you do the aero ports you need to make sure you need to have 4" between the end of the port and the wall which you wont be able to have with a 25" long port within your dimensions Quote 1999 Audi A4 1.8T::: 4 - DC Level 3 10's in a 4th order Rockford P6002 on Subs for now (3-3.5k coming eventually) MB Quart ONX4.60 for Mids and Highs Boston S50 Components in Front Boston S65 Coaxials in Rear 40 Sq Ft of Second Skin Damplifier Build Thread UBL 1948 Plymouth Link to comment Share on other sites More sharing options...

So I guess I am going to try to do a slot port instead...
