SCOTT KOCH Posted June 14, 2012 Report Share Posted June 14, 2012 I agree with Joe x......build to 1.0 to 1.2 sealed and go with it.....I'm getting ready to do the same thing but with one type r......in a civic hatch...ohhh can't wait. Sealed is definitely better for deep solid bass!! Link to comment Share on other sites More sharing options...
logspace Posted June 14, 2012 Author Report Share Posted June 14, 2012 Thanks for the advice everyone. I think I will try sealed first, and if the sound isn't where I want it to be I will build a ported box like Joe said. Link to comment Share on other sites More sharing options...
Joe X Posted June 15, 2012 Report Share Posted June 15, 2012 Ok so here is a an example for a 1 cube enclosure that includes the driver displacement of the 1242D which is 0.071 cubes. Enclosure Specifications: Vb = 1 ft^3 External Height = 14 in External Width = 17 in External Depth = 11 in Cut Sheet List: * All Dimensions in Inches. * Wood Thickness is 3/4 for all Parts. External Enclosure Parts: Front & Back = 17 x 14 Left & Right Sides = 9 1/2 x 12 1/2 Top & Bottom = 17 x 9 1/2 Link to comment Share on other sites More sharing options...
logspace Posted June 15, 2012 Author Report Share Posted June 15, 2012 Thanks for the specs. I was also wondering if the shape of a sealed box affects the sound. For example, would a hatchback style box have any different sound qualities than a cubic or rectangular shape box? Link to comment Share on other sites More sharing options...
Joe X Posted June 15, 2012 Report Share Posted June 15, 2012 In cars the shape of the enclosure is really defined by the space you have available, if you have a choice avoid perfect cubes if you want to avoid coloration of sound, a rectangular box similar to the one I suggested will be easiest to build and give nice results. Slanted boxes are considered by some as better sounding but are much harder to build. Link to comment Share on other sites More sharing options...
logspace Posted June 15, 2012 Author Report Share Posted June 15, 2012 Ah ok. I was just visualizing sound waves and interference, then i got to thinking that some designs could potentialy cause standing waves. Thanks Link to comment Share on other sites More sharing options...
Joe X Posted June 15, 2012 Report Share Posted June 15, 2012 Right perfect cubes can develop strong SWs. Link to comment Share on other sites More sharing options...
