Purplehaze Posted January 4, 2012 Author Report Share Posted January 4, 2012 I can plug everything into sketchup if you'd like. I'm sittin at the girls house pretty bored and this would give me something to do lol Yes please! That would be sweet! I was gonna change the baffle a little, just a little angle, no real changes. just add 2" to the back side inner sealed width, and subtract 2" from the opposite side. If you could incorporate that, I would appreciate it! Hell I appreciate it even if you can't! Thanks man!

D-train-13k Posted January 4, 2012 Report Share Posted January 4, 2012 Okay, so I came up with some new numbers, same design. See what you guys think of this one? External: W 47" L 68" H 18" Internal: W 45.5" L 66.6" H 16.5" Sealed Inside: W 7.208" L 66.5" H 16.5" 4.08ft3 x2 1.35ft3 per sub after displacements Ported Inside W 29.583" L 66.5" H 16.5" 16.89ft3 after port, sub, and bracing 2.81ft3 per sub Port H 14" W 18" L 6" - 3" external 14.92in2 port area per foot 252in2 port area total 46hz tuning just so you know the way the blow throughs are set up the tunnel effect is going to drop your tuning no matter how you tune it. so unless you like low low bass then id bring it up a little to 48 or so also id try to make the port closer to 17 per. but i like ground pounding so thats my opinon The IrishmanCheck out my build hereXL 4th order wall build logIn Progress:alpine cda HU4th order Bandpass2xl 15's1- ab 400.1 (gonna be two hopefully)4- Crescendo 8's2- xts crecendo supertweeters 2 sq super tweetsMb quart 4.125Mechman 270a alt1- xs D27003- xs XP3000 4- odessey pc1700seller feed back threadhttp://www.stevemeadedesigns.com/board/topic/136418-d-train-13k/ Link to comment Share on other sites More sharing options...

tctdh11 Posted January 5, 2012 Report Share Posted January 5, 2012 Already started doing it that way bub. lol What ratio are you trying to achieve? 2:1 I'm assuming. I noticed on your the figures you gave the area wasn't correct. So what are you wanting the internal areas on both sealed and ported sections to be at?

tctdh11 Posted January 5, 2012 Report Share Posted January 5, 2012 So where should the tuning be? with the numbers i've got right now i'm at... 8.13 sealed before displacement of bracing 17.52 ported after sub and port displacement 17.19 area per foot 48.06hz tuning 2.16:1 ratio TEAM DC www.dcsoundlab.com 2003 Tiburon GT V6 6 Speed Ported Clam 6 12" DC Audio XL M2's 2 American Bass 1100.1 1 American Bass 350.4 3 D3100, 1 D975, 3 D925 Second Skin Damp Pro and Spectrum.

99fullsizechevy Posted January 5, 2012 Report Share Posted January 5, 2012 The whole point or me doing a blow thru is for the massive low end response it is going to yeild. I wouldn't mind having some playability on normal rap songs in the upper span, but full tilt my goal is for 150s in the lower 30 hz range and just kill all the way down into the mid-low 20hz range... And yes was going for a 2:1 ratio within the space I have.. It may be a little smaller than it probably should be but a stepside bed only has so much room Laying frame soon.. System has to wait Link to comment Share on other sites More sharing options...

If so I'll finish up the Sketchup and post it at those specs.
