steve volz Posted February 16, 2012 Report Posted February 16, 2012 I have 3 10s in a ported box. I was having air noise problems so I added more ports because I was told there wasnt enough port area. The box is 4.2ft^3 with 4 3inch ports tuned to 32hz. now after i added ports, on some songs im either bottoming out or clipping. my subs frequency response is 29-250hz. what do you think and how can i fix it.

donpablo Posted February 16, 2012 Report Posted February 16, 2012 (edited) Are all your gains set corretly Also use torres box calc to make sure the ports are right Edited February 16, 2012 by donpablo Quote 2015 F-150 Platnuim
Joe X Posted February 16, 2012 Report Posted February 16, 2012 If you want a specific fix you should provide specific data, box dims port lengths, subs and amp you are using. For ex. wrong tuning can lead to that issue but also amp settings can. Quote
steve volz Posted February 17, 2012 Author Report Posted February 17, 2012 thats the calc i used to do the ports. i guessed on the gain but i know im close i think i figured it out i built an amp rack at the same time the ports were added and the amp rack might b hitting the back of the box Quote http://www.stevemead...new-xfl-pg6-57/americanbass hd 12d22 audiopipe 1800.1ppi s580.4rockford p1653 frontpolk audio 6x9 rearbig 3
donpablo Posted February 17, 2012 Report Posted February 17, 2012 I guessed on my gain to then my dd-1 came and damn i was surprised lol Quote 2015 F-150 Platnuim
412 CVX Posted February 17, 2012 Report Posted February 17, 2012 four 3" ports is not enough for a 4 cubic foot box. box building is NOT a guessing game. Quote Just say no to Ground Pounder Customs. My temp system build log More box buildssome cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches! I'm with captain stupid.
steve volz Posted February 17, 2012 Author Report Posted February 17, 2012 I dont have room for any more ports on the front of the box unless i take out 2 of them and find some oval shaped ports. I wish I could get a dd-1 but i dont have the money right now Quote http://www.stevemead...new-xfl-pg6-57/americanbass hd 12d22 audiopipe 1800.1ppi s580.4rockford p1653 frontpolk audio 6x9 rearbig 3

I wish I could get a dd-1 but i dont have the money right now Steve, if it was playing right before despite the noise, maybe is not the amp settings, share your dims, port lengths if it is the box it can be fixed, maybe there is an issue with the data you entered, at least in one machine I know the Torres misbehaved giving ridiculous output.
