joemon Posted January 25, 2012 Report Share Posted January 25, 2012 i just got a pair of lvl4 12 d1 hooked on a 2600watt amp and was wanting to make my own custom ported box for these. my question is with my dimensions (WxHxD) 30x13x25in outside dim. using 0.75in thickness, what size port and how many should i use to tune to 34hz using aero ports? i believe the box will be 4.46cubic ft. b4 sub and port displacement. thanks for your time and great work on the DC product i love these subs so far and will love them more after this box. lol -Joseph Quote stevemeadedesigns.com/board/topic/105505-silvia-first-time-build-kenwood/ Link to comment Share on other sites More sharing options...
