cris2216 Posted May 2, 2013 Report Share Posted May 2, 2013 I want to build a 4th order bandpass box to use as a blowthru in my 2010 silverado. The specs i came up with is a 2:1 ratio, 12 ported and 6 sealed for 6 sundown SA 12's tuned at 42hz. Are these specs ok or is it too small?? I want to hit the lows (24hz-28hz) if anybody has any suggestions tell me Link to comment Share on other sites More sharing options...
CleanSierra Posted May 2, 2013 Report Share Posted May 2, 2013 Tuned way too low in my opinion. You might be able to hit the mid 20s but what about mid 40s(where a lot of audible bass occurs)? I would get tuning up a few more Hz, at least to 45 is 46. A 2:1 should have a decently flat response, therefore having some breadth in the frequency range. Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...
