Im trying to choose between the Digital designs 2500 or alpine type R and had one more question. I want to run three 12s, I already have 2 12" audiobahn se's that i am going to run in the same box with either the type r or the dd until i have the money to buy 3 of the type r or dd. My question is what should i tune the box to? I want it tuned to as if i already had three of either or. Untill i found this website i had never even heard of tuning boxes. Thanks for all the advice and to everyone else who has helped.
hmmm.... i'm not sure about putting two different kinds of subs in a box, especially audiobahns with a DD, but i would think you should tune it to the low 30's.
