I decided to build a ported box for my atlas and this is my first ported box. I think I have all of the measurments correct but I just want to be certain so I don't waste a lot of wood. The link to my design is below. Any suggestions are welcome. Thanks in advance for any help.
Also my amp doesn't have a subsonic filter on it but I remember something like a Harrison Fmod or something like that to substitute as the subsonic filter. If anyone has information on that I would greatly appreciate it.
