  • 7 months later...

I have reread this build log of recent...

clamping 4kw i get a 153.9 at 37hz has been my best sealed up on the dash score...

this is with less than 12sq inches of port per cube...I have decided i simply dont have the power to make it loud. But interesting our scores were so close with so many different variables. :drinks:

once i got the box's shrunk my score went up to 154.6 at 34 hz with 2 powerbass xa3000ds

so probably with 6k on tap but i had 16 volt setup and 14 batteries

30 cube box total 6 cubes sealed 24 cubes ported with 760^2" of port

oh how i miss her :(

What do you mean shrunk? Do explain...i have 1.5 per sealed but my subs have a very stiff spider back probably killing my efficiency...

i shrunk the sealed box's by adding 2x4s on the inside of sealed box's going from 1.5 to 1.3 or so

and these apxx's were stiff as hell when i had them in exploder

R.I.P!
