OrionStang Posted August 3, 2010 Report Share Posted August 3, 2010 If your talking round ports, use Torres calculator. If they are flared, I find the desired freq, and add an inch for the flares. Also, two 6" ports is probably not enough area for a box that big. I got three 6" aeros in a 13 cube box.

Tek Posted August 3, 2010 Report Share Posted August 3, 2010 The more ports you have, the longer you need to make them to get low. Its a pain in the ass really Quote Link to comment Share on other sites More sharing options...

lowhzdime Posted August 3, 2010 Author Report Share Posted August 3, 2010 i also have enough 6" pvc if that would work better Quote Link to comment Share on other sites More sharing options...
Torres Posted August 3, 2010 Report Share Posted August 3, 2010 The more ports you have, the longer you need to make them to get low. Its a pain in the ass really not necessarily. if the port area remains the same, then the port length will also be the same. the length should be right around 7.5" long to get that tuning. tho...that only gives you about 7.5 sq inches of port per foot. kinda low imo. you'd need something like 6 6" aeros at 12.5" long each to get a 35 hz tuning Quote Link to comment Share on other sites More sharing options...
