+ZER0Hz+ Posted November 5, 2007 Report Share Posted November 5, 2007 Ok, ive been debating about making a box, and ive finally figured something out.... Ported (with interchangable ports) tuned to 45 Hz and 30 Hz 32x18x18 Subs up Port Back 10Hx4W Port (interchangable) Can somebody help me with the port lengths, and how this will look? Its 2 12" subs by the way... also just to see if my math is right, i did this in class, so it might be wrong with displacement, etc... Using 3/4" MDF, double baffle, double thick on port side External: 32Wx18Hx18D Internal: 30.5" or 2.541' 15.75 or 1.313' Equals 4.14ft^3 volume Minus about .28ft^3 for displacement Equals 3.96ft^3 Correct my math if im wrong Thanks again! :D 2009 VW Rabbit 2-Door: Pioneer AVH-X1600DVD Kicker CX600.1 (Kicker "Certified" 638wrms@2ohm) NVX VCW124 @2 Ohm, ~1.25 ft^3 Sealed box Stock Doors; (4) 6.5's, (2) 4's, (4) 1" Tweets Owner/Founder of RT Photography Canon Traitor who moved to Fujifilm Link to comment Share on other sites More sharing options...

andym85 Posted November 5, 2007 Report Share Posted November 5, 2007 its not 15.75" its 16.5 silly (18-1.5)...anyways its 4.805 gross...after u port at 45hz and account for sub disp, then its 4.21cubes net and your port needs to be 7.5" for 45hz, and for 30hz its needs to be 30" long and that box will be 3.39cubes net i likes me some audio stuff...
