Silver Member Username: TheweaselSteamboat springs, Colorado U.S. of A Post Number: 831 Registered: Mar-06 | i'm trying to keep the box as small as possible, so should i reduce the port area from 72" sq in to 52 sq in, or reduce the volume from 4 cu ft to 3.6 cu ft. |

Bronze Member Username: CsuhoNashville, Tn Post Number: 21 Registered: Jun-07 | if you reduce your box volume then the port will have to be reduced also. imo you have an optimun box for a pair of 12s with nice port area too. or if you want make the port 12.5x3.25x20 ok make the box this then if want to same on space 32x14x21 that will give you a volume of 3.75 after port after doing a little math u must have some big 12s. the port i just gave ya is 40"sq instead of the 50" in the first post. to be honest i am not sure i would go smaller than that box i just gave ya since you will be choking the subs. they wont be able to perform as well as they should. if you need to make the box smaller either go with 1 sub or go sealed. |
