Bala-the-pig Posted April 10, 2018 Report Share Posted April 10, 2018 Okay people so i designed this box last night and i got 5.5 cu ft after displacement. I got 8.78 cu ft before displacement. Is that too much?? Its tuned to 34 hz, subs take up.25 cu ft each and i am going to run 2 12s which are 2000 rms. Port displacement=2.78 cu ft Sub displacement= .50 cu ft Port is double layer starts off as 15" height and is 38.93" in length. The Width of the port is 7.5".

Kraken Posted April 30, 2018 Report Share Posted April 30, 2018 What subs are you running? It seems to work in my eyes. Although I would throw those numbers in Torres and make sure it checks out. Alpine cde143bt/ Alpine ktp445u (4x45 amp) 2 Crescendo STS 1 (on alpine 4x45 on 2 channel mode) 4 Crescendo pwx 6.5's in front doors (Skar RP150.4) 1 Sundown zv3 12, SAE1500D. Box is 2.5 cubes tuned to 30hz. Link to comment Share on other sites More sharing options...
