Sufkayx Posted March 15, 2017 Report Share Posted March 15, 2017 Hi all I have just bought two 12 Alpine type r 12d2s 1000 RMS each. I am looking to put them in ported enclosure but need help on what size to use. I'm looking for deep loud and low bass with the best frequency respose possible. I am able to fit a 4 cubic foot box in my trunk after port displacement and sub displacement. Also if I tune to say 32hz will I get enough bass upwards of 45hz or will it start to roll of/ Also what size port should I use I was thinking 3 inch wide 12 high does port size affect frequency response such as making the response shorter or longer. Hope some one can be of assistance Quote Link to comment Share on other sites More sharing options...
