Krakin Posted March 12, 2013 Report Share Posted March 12, 2013 What are the height, width, and depth? Krakin's Home Dipole Project http://www.stevemeadedesigns.com/board/topic/186153-krakins-dipole-project-new-reciever-in-rockford-science/#entry2772370 Krakin, are you some sort of mad scientist? I would have replied earlier, but I was measuring the output of my amp with a yardstick . . . What you hear is not the air pressure variation in itself but what has drawn your attention in the two streams of superimposed air pressure variations at your eardrums An acoustic event has dimensions of Time, Tone, Loudness and Space Everyone learns to render the 3-dimensional localization of sound based on the individual shape of their ears, thus no formula can achieve a definite effect for every listener.

Krakin Posted March 12, 2013 Report Share Posted March 12, 2013 Okay so the port you have would be a "0" common wall port. That is unless you have it in one of the corners of the box.

stroupe79 Posted March 12, 2013 Report Share Posted March 12, 2013 if the port is an L (3common walls) you need to have the same width as the port opening after the bend....like this if the port is in the center (2common walls) and longer than the box is deep you would split the port in 2 and it would be half the width going each way after the bends....like this http://www.stevemead...cherokee-build/ 2005 Jeep Grand Cherokee Alpine CDE-hd148bt Alpine PKG-RSE2 PRV Audio (4) 6MB200 front/rear doors PRV Audio (4) TW350Ti dash/rear doors Kicker KX350.4 Obsidian Audio (1) 18 D4 v2 revamp (2) Stereo Integrity HT 18d2DC Audio 1.2k5.25ft^3 tuned @34hz revamp Infinite Baffle Cpillar AudioTechnix 60mil deadenerKnuKonceptz & SkyHigh wire (complete setup) Link to comment Share on other sites More sharing options...
stroupe79 Posted March 12, 2013 Report Share Posted March 12, 2013 if you haven't built a ported box before, odds are slot ported (L port) would be easier for you....I would go with something in this neighborhood h26 x w44 x 26d port and subs facing forward with double baffle and .75 thickness...you would need to brace it a bit inside... port h24.5 x w6.5 x 28l gives you 10.2cubes with tuning of 31hz and port area per foot of 15.62 that would be pretty nice to run 2 18s...you could have the subs/port facing up as long as you have room for the port to breath, but 26inches high in a backseat you might as well wall it and fire everything forward! http://www.stevemead...cherokee-build/ 2005 Jeep Grand Cherokee Alpine CDE-hd148bt Alpine PKG-RSE2 PRV Audio (4) 6MB200 front/rear doors PRV Audio (4) TW350Ti dash/rear doors Kicker KX350.4 Obsidian Audio (1) 18 D4 v2 revamp (2) Stereo Integrity HT 18d2DC Audio 1.2k5.25ft^3 tuned @34hz revamp Infinite Baffle Cpillar AudioTechnix 60mil deadenerKnuKonceptz & SkyHigh wire (complete setup) Link to comment Share on other sites More sharing options...
SGT_76 Posted March 12, 2013 Report Share Posted March 12, 2013 Unless I missed it, you never stated what brand/model of sub your trying to build this for? Or if you are planning on powering them at, below or above their rated rms? This will make a huge difference in your design. All the "general" box, port and tuning information already provided look to be inline with all my reasearch, but the specific sub/s and power you decide on will effect your general design making it necessary to be fine tuned to what "your" sub/s actually like.

At 26" high i could still see out my rear window which is why i'm not walling it. Unless I missed it, you never stated what brand/model of sub your trying to build this for?

Right now the plan is to run each sub on a t1500.
