So I have 2 18 in. Incriminator Audio Death Penalty and I am looking for some info on doing them in a 4th order wall. Looking to do subs on the outsides with port in the middle.
1. I can't find the sealed specs for them anywhere so were do I start on it. I am obviously doing a wall so I need to do it as close to right as possible the first time since wood is pricey.
2. The box ratio needs to be 2:1 I have read...sooo if I do 3.25 cubes for the sealed sides do I need to do 13 cubes for the ported area in the middle?
3. How would I go about doing the tuning? Should I tune high and let the sealed areas do the work with the SQ aspect or should I just tune like I usually would for a SPL box?
