fecupe2001 Posted November 15, 2010 Report Share Posted November 15, 2010 (edited) Hey guys, i don´t know how to use any sketching program or anything but it´s ok, i just want you to check the size and ratios of a 4th order i´m designing for my friend´s nissan almera, i´ve designed and built lots of boxes before, and also, a few Bandpasses but nothing major, i just want to double chek with you guys, few heads thinks better than one Anyways, the box is for 4 Digital designs 2515 , it´s gonna use about 6000 watts, we don´t know yet. 3:1 RATIO 24 cubic feet after displacement. 6 cubic feet the rear chamber, 1.5 cubic feet per each 15" sub 18 cubic feet the front chamber with 370 SQ of port , 20 SQ per cubic feet tuned @ 45 hz This is meant for hairtricks, demos and daily listening, maybe i´ll build another port for comps, don´t know yet, but main goal with this design it´s to have a very good musical box that still scores a nice number Sounds good? any comment, opinion and advice are welcome, i don´t wanna mess up and lose tons of money and time building this hehe, cheers!!!

Thanks a lot for the input man, i fucking hate not knowing how to use a sketching program, i´ll have to learn hehe, anyways, i still don´t know how i´m gonna mount the subs yet, it´s a trunk car, i have two options , mounting them on the "floor" of the box just like rival´s design, or, getting them on the back of the box with a vertical port on the center of the car, i can´t get the port on the driver´s side because this car is gonna compete on bass race, and over here, we bass race with driver´s door open. If the sealed chamber it´s on the back, i guess i´ll have to mount them on "zig zag" , i´ll take care of that later, first i want to be sure on the measures , i actually want to build a flat wall because of the space, but he wants something different tho.

fecupe2001 Posted November 15, 2010 Author Report Share Posted November 15, 2010 Morning BUMP question, what about the sealed box? should i do common chamber or each sub on it´s own box?? it´s gonna use a single amp by the way.

uhoh_45 Posted November 15, 2010 Report Share Posted November 15, 2010 keep the sealed box's separate if your looking for numbers 4rth orders take lots trial and error the A-team had explained bunch bout his 4rth order ( 6 lvl 5 12s) that you do separate chambers so you can fine tune each sub individually say one chamber is 1.4 cubes where another could be 1.3 and so on i know with my box's i built them to 1.5 and found they liked smaller sealed box's so i ended up shrinking the box's to 1.35sh by adding bunch 2x4s on the inside of my box's to shrink them hope this helps Quote R.I.P!
