its made from 5/8mdf
external dimensions
15" height
25" wide
16.5" deep
port is 2" wide and 30" long
I feel like this might be a little small for my 12" alpha...what is it tuned at?? is the volume to small? |

its a 30" slot port that bends..
its not prefab...
and i could only find 5/8 so i just doubled most of it, but not all of it, so i gave what the dimensions would be if it was just single 5/8 with the same internal volume.
im useing an ample audio 300dx to push it..1500 watts at 1 ohm |
