dudeogo Posted June 18, 2017 Report Share Posted June 18, 2017 I want to put two lethal injection 12s in the back of my grand Cherokee in a 6th order. Anyone available to help? I have absolutely zero experience with 6th orders.

Triticum Agricolam Posted June 18, 2017 Report Share Posted June 18, 2017 What's your reason for wanting a 6th order? What amp/s are you running?

I really want the high output at a small band somewhere in the lows. I'll still listen to music on it, but I was to have those few frequencies in demo music that will kill. Also this is a temporary box for while I buy my other two 12s and I've always wanted to try a 6th. No power decided as of yet. Probably going to try to find a nice 2500 Stage 3 2008 Mazdaspeed 3 MIDS/HIGHS BASS 8 Unlawful Sounds Mark VIIIs 2 15s (in talks with a few companies) 8 Unlawful Sounds Super Tweeters Soundigital EVO 5000 Amps: Something Brazilian Link to comment Share on other sites More sharing options...

dudeogo Posted June 18, 2017 Author Report Share Posted June 18, 2017 If I end up hating the output and it's not for me I'm capable of designing a standard ported box.

Triticum Agricolam Posted June 19, 2017 Report Share Posted June 19, 2017 OK, here is what I came up with. I did two designs, a series-tuned box and a parallel-tuned box. First off is the parallel-tuned box. The specs are: Rear chamber - 5 cu ft net - 27 Hz tuning - 60 sq in port area Front chamber - 2.5 cu ft net - 55 Hz tuning - 60 sq in port area Exterior dimensions - 39" W x 19.5" H x 27.5" D. All panels except top and bottom are 18" wide. Next is the series tuned box: Rear chamber - 3.35 cu ft net - 28 Hz tuning - 75 sq in port area Front chamber - 4.8 cu ft net - 59 Hz tuning - 75 sq in port area Exterior dimensions - 39" W x 21.875" H x 27.5" D. All panels except top and bottom are 20.375" wide. Here is a comparison of the simulated frequency response curves of both boxes, this does not include any cabin gain, which will boost low frequencies output considerably: The red line is the series-tuned box and the green-line is the parallel tuned one. Pretty similar bandwidth for both, though the parallel-tuned box is smoother. If it were me, I'd pick the parallel-tuned box since it has smoother frequency response, more output above 30 hz, is smaller, and is less finicky than a series-tuned box is. The series tuned box will probably get you more output real low though. If you are really feeling adventuresome you could build both and see which you like best :-) "Nothing prevents people from knowing the truth more than the belief they already know it.""Making bass is easy, making music is the hard part."Builds: Link to comment Share on other sites More sharing options...
