      So Its upgrade time and I plan on running 2 ascendant audio chaos 12s out of a trunk with the trunk being sealed, i would like to have the subs firing the same side as the port into the cab with the port centered between subs. Im looking for something with 4 cubes not including the displacements. tuned to 32 hz with 64" of port area and a 1.5" baffle i plan on using 1/2" allthread for bracing so it wont be an issue in taking up air space. Ive come up with a few designs but they dont work out, i need the box to be 34" wide with the height being 15" the depth cannot be greater than 26" thanks for the help!!! Also will be running on rated power

      I need a box for my sundown zv4 15 rev1. Ive got it on a hifonics 1800.1 at 1 ohm. It slams right now in its current box but It sounds like the box is tuned to 35 or 36 hz. I want to build a 30hz or a low slamming box. Im new to building boxes but I work for a cabinet company so am pretty good with wood work and measurements and I have the tools so I thought I would give it a shot. What would be a good low hitting box tuned to 28-30hz for the zv4 15. I also want to know what program is good for tuning and sizing your boxes. I drive a mercury grand marquis so space isn't really an issue. Could someone design me a box for this thing that would slam 28-30hz? Any other ideas?

      I've seen quite a few write-ups on 4th order ratios and what not, but am struggling to find anything on 6th orders. what would a 1:1 compared to a 2:1, 3:1, etc. ratio 6th order sound like? Thanks!
