jessdabest77 Posted July 29, 2019 Report Share Posted July 29, 2019 Wanting help designing a ported box tuned to around 31 32 Hertz. For two Sundown SA 12s. Space available is 30.5" Wide x 16" Height x 24.5" Depth. It'll be ran of a 2200 watt amp at half ohm. Should it be a side or middle port. Would like it tuned low thanks in advance.

I wouldn't tune the SA series to 30hz personally. 33hz minimal with subsonic set to around 28 at the lowest. Preferably 30hz. They only have like 16mm xmax and don't particularly like lows. They snap hard from 33up though. Link to comment Share on other sites More sharing options...

Jessica Posted July 29, 2019 Report Share Posted July 29, 2019 I dont know if you conisdered the trunk opening or not so you may have to build this in the trunk. im using your max dimensions. You dont have to do the 45°s but i would recommend at least doing the triangle in the back of the port. 45's should help and i personally would do them. you can mount the subs on the front or top of the box, you choice. not sure what makes your car get loud but keep in mind this box is at your max height and the subs will add to that if you mount them on top. There is just enough room for the subs to mount with the width provided. you have 11 3/4" width internally and the SA'12 has an 11 1/8" mouting width. your cutout will have to be precise. I encourage you to get a second opinion as well. Plenty of guys here who design boxes. Let me know if you have any questions (edit: spelling) Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside. My super random youtube channel and terrible camera work.

shredder2 Posted July 31, 2019 Report Share Posted July 31, 2019 Shouldn't port pictured above in Sketchup be 1/2 the 4" width on each side after the bends along the backwall? Maybe I'm delusional but the 4" width looks uniform throughout. Link to comment Share on other sites More sharing options...
