bassfreak85 Posted April 14, 2016 Report Share Posted April 14, 2016 7 cubes per woofer i wouldn't go much more than that per 18. i think 22 should work out nicely Link to comment Share on other sites More sharing options...
xile Posted April 21, 2016 Author Report Share Posted April 21, 2016 Any more input before I start this. Current box plan is 48"w 40"d 24"t with a 9"w 15"t 6"d rectangle port placed in the middle of the box. Thanks Link to comment Share on other sites More sharing options...
Triticum Agricolam Posted April 21, 2016 Report Share Posted April 21, 2016 Your port is way, WAY too small. It should be like two or three times that big.

xile Posted April 21, 2016 Author Report Share Posted April 21, 2016 I used box tune calculator to figure out the box and it says that should put me around 32hz. Link to comment Share on other sites More sharing options...
Triticum Agricolam Posted April 21, 2016 Report Share Posted April 21, 2016 I'm sure it will but that doesn't mean it's enough port area. You can have a much bigger port and still tune it to 32 Hz.
