well first off Hello to all the people on this forum. this is my fist post and I want to figure some stuff out. OK first off I am a "nood" when it comes to box building. and I have come to the decision to purchase 2 12" Rl-p's because well they look like damn sexxxy subs and people have said good things about them..NOTHING BAD!!!. and the price is great. anyhoo. I need help getting box specs for my pathfinder. I have no clue on tuning a box. and what would the best tuning be for them. in a ported box. That is a little drawing of what my specs are for my pathfinder. if anyone can help me design a box for 2 12"s ported. [i dont know what the best frequency would be for them] 28-32hz??? I want to keep it 19" tall thats about it. the amp.. I am probably going to go with a Ed NINe.1 1200x1 1ohm. and another quick question. lets say the box was tuned to 28hz and i played a 20hz tone. does this make the sub bottom out or what not. just kinda curiouse... Thanks for any help people post.......peace.
