dwright27 Posted December 25, 2010 Report Share Posted December 25, 2010 45 Hz. 14 square inches of port per cube. 4 - 8 cubes on the sealed side. depending on your power, and 8 - 24 on ported side.

splzx3 Posted December 25, 2010 Author Report Share Posted December 25, 2010 it will be a aq3500d.1 for now on each sub Quote ________________________________________________________________________ deepsilencer, on 22 Aug 2011 - 17:32, said: splzx3, on 22 Aug 2011 - 17:27, said: i had my fun on one of his videos...till he blocked me then i got my mother into it lol after her he closed the comments xD lol your mom is a G!

dwright27 Posted December 25, 2010 Report Share Posted December 25, 2010 with your available space, i would do 5 - 6 cubes sealed, with 10 - 18 cubes ported. id probably start with 6 sealed and 18 ported. i wouldnt glue anything in except the outer walls/shell, and then start testing. i would also put the magnets in the ported chamber. to shrink the chambers just start adding more layers to the shell. grab a termlab and go to town Quote 2006 F-150 4 DC XL M2 18's Walled Daily Driver XS Power 4 DC 3.5kw Team DC Team S.P.L.

fecupe2001 Posted December 25, 2010 Report Share Posted December 25, 2010 My boy dwright knows a lot already about 4th orders, i do think what he´s telling you is a very good advice, with that amount of power you woul have to build a small sealed chamber, i would try a 3:1 ratio, 4 c/f on sealed chamber and 12 c/f on the ported with a 45 hz tuning, 18 SQ of port per cubic feet so you can shrink the port area testing everything.

dwright27 Posted December 25, 2010 Report Share Posted December 25, 2010 Try 8, 12 and 16 for ported side. That's total size. Test test and test some more Quote 2006 F-150 4 DC XL M2 18's Walled Daily Driver XS Power 4 DC 3.5kw Team DC Team S.P.L.
