basshead7890 Posted September 13, 2011 Report Share Posted September 13, 2011 (edited) I read that you take the maximum size of the recommended sealed enclosure for the sealed chamber, but how do you calculate volume of the ported chamber? Also is tuning the port the same as a regular ported enclosure?

RAM_Designs Posted September 14, 2011 Report Share Posted September 14, 2011 (edited) You tune higher with a bandpass box. The volumes used in each chamber are determined by the subs being used and the end result(response curve) that you're looking for.

Ray Posted September 14, 2011 Report Share Posted September 14, 2011 if you want a flat resp go vented size half of the sealed side if you want loud and a number vented side should be roughly 2x the sealed side Quote 2008 California state record holder 157.2 Bassrace2009 California state record holder 157.0 BassraceRollin 50's 158.7db2009 King of Cali Bassrace2009 USACi score 160.5 @ 42hz Link to comment Share on other sites More sharing options...
basshead7890 Posted March 1, 2012 Author Report Share Posted March 1, 2012 I'm trying to design a 4th order through the armrest for 2 sundown e12's for an Acura tl and I'm using the calculator at http://www.carstereo.com/help/Articles.cfm?id=27 I'm wanting to know if the calculator is correct, and is the F3(L) the low end tuning frequency of the whole box or just the ported side? thanks for any comments Quote My Build Log 95 Honda Accord Nook HD+ tablet Team Ascendant Audio 18" 2 Skar Audio SK-2500.1D Crescendo Audio C1100.4 2006 Civic, Fi SP4 12", bc3500 Build log Link to comment Share on other sites More sharing options...
Ray Posted March 1, 2012 Report Share Posted March 1, 2012 Do a 6th order thru the armrest. Mucho better.
